Habitat for Humanity – Yelm Plat Operation and Maintenance Manual OPERATION AND MAINTENANCE MANUAL / STORMWATER FACILITY MAINTENANCE PROGRAM HABITAT FOR HUMANITY – YELM PLAT 407 LONGMIRE ST NW, YELM PARCEL NUMBERS: 22719230700 SECTION 1: PROJECT DESCRIPTION Description of Drainage System and Facilities serving the site: The proposed project improvements are considered to be four drainage basins. Stormwater runoff within Basin 1 will be collected by catch basins and conveyed to a bioretention pond where the stormwater runoff will receive enhanced treatment before fully infiltrating on-site. Stormwater runoff from the roof areas in Basin 2 will be conveyed to individual infiltration facilities located on each proposed lot where the stormwater runoff will be fully infiltrated. Stormwater runoff within Basin 3 will sheet flow to an infiltration pond located within the rightof-way of Longmire Street NW to account for the stormwater runoff that can no longer enter the City system located along Coates Ave NW. Stormwater runoff within Basin 4 will continue to flow into the City system located along Coates Ave NW. Typical maintenance of the stormwater system includes removing debris from catch basin grates, removing sediment from pipes, catch basins, infiltration facilities, and bioretention pond, as well as typical bioretention pond maintenance such as replacing the bioretention soil media. The drawings of the stormwater facilities are found in Appendix 4 of the Stormwater Site Plan. See Appendix 3 of the Stormwater Site Plan for a Basin Map Exhibits as well. SECTION 2: MAINTENANCE IMPORTANCE AND INTENT Intent: The importance of maintenance for the proper functioning of stormwater control facilities cannot be over-emphasized. A substantial portion of failures (clogging of filters, resuspension of sediments, loss of storage capacity, etc.) are due to inadequate maintenance. Stormwater BMP maintenance is essential to ensure that BMPs function as intended throughout their full life cycle. The fundamental goals of maintenance activities are to ensure the entire flow regime and treatment train designed for this site continue to fully function. For this site these include: • Maintain designed stormwater infiltration capacity • Maintain designed stormwater detention/retention volume • Maintain ability to safely convey design stormwater flows • Maintain ability to treat stormwater runoff quality LDC Inc . Habitat for Humanity – Yelm Plat Operation and Maintenance Manual • Preserve soil and plant health, as well as stormwater flow contact with plant and soil systems • Clearly identify systems so they can be protected • Keep maintenance costs low • Prevent large-scale or expensive stormwater system failures • Prevent water quality violations or damage to downstream properties The intent of this section and manual is to pass on to the responsible party(s) all the information critical to understand the design of the system, risks and considerations for proper use, suggestions for maintenance frequencies, and cost so that realistic budgets can be established. SECTION 3: RESPONSIBLE PARTIES Owner Information: South Puget Sound Habitat for Humanity will be responsible for maintaining the community bioretention pond and associated conveyance systems until the homeowner’s association (HOA) takes over responsibility. The individual lot owners will be responsible for maintain their roof drywells. The stormwater facilities maintenance plan will be kept in safe and well-known place and will be made available for inspection to the City upon request. See the general requirements below regarding frequency of inspections. SECTION 4: FACILITIES REQUIRING MAINTENANCE General Requirements: 1. Maintenance Required – all stormwater facilities shall be maintained in accordance with this maintenance program, the drainage report for the Habitat for Humanity – Yelm Plat project, and the most current version of the City of Yelm Design Standards. 2. Minimum Standards – the following are the minimum standards for the maintenance of this project’s stormwater facilities. a. Facilities shall be inspected annually and cleared of debris, sediment, and vegetation when they affect the functionality and/or design capacity of the facility. b. Landscape and lawn/turf areas shall be inspected quarterly and mowed and replanted as necessary. Clippings are to be removed and properly disposed of. c. Where lack of maintenance is causing or contributing to a water quality problem, immediate action shall be taken to correct the problem. Within one month, after initial recognition of the problem, a City of Yelm inspector may revisit the facility to assure that the problem has been rectified at his or her convenience. 3. Disposal of Waste from Maintenance Activities – disposal of waste from maintenance activities shall be conducted in accordance with City of Yelm’s waste disposal standards. LDC Inc . Habitat for Humanity – Yelm Plat Operation and Maintenance Manual 4. Compliance – property owners are responsible for the maintenance, operation or repair of stormwater drainage systems, and project installed BMPs. Property owners shall maintain, operate, and repair these facilities in accordance with the requirements of this maintenance program, the drainage report, and the most current edition of the Department of Ecology Stormwater Management Manual of Western Washington (SWMMWW). SECTION 5: MAINTENANCE INSTRUCTIONS The parties responsible for maintenance must review and apply the maintenance requirements contained herein. These maintenance instructions outline conditions for determining if maintenance actions are required, as identified through inspection. However, they are not intended to be measures of the facility’s required condition at all times between inspections. Exceedance of these conditions at any time between inspections or maintenance activity does not automatically constitute a violation of these standards. However, based upon inspection observations, the inspection and maintenance presented in the checklists shall be adjusted to minimize the length of time that a facility is in a condition that requires a maintenance action. For facilities not owned and maintained by the city, a log of maintenance activity that indicates what actions were taken must be kept on site and be available for inspection by the city. Inspection Program: 1. Inspection – it will be the responsibility of the Owner to complete the necessary stormwater inspection tasks stated herein and prepare the inspection reports that will be submitted to the city of Yelm. Inspection reports shall be submitted annually or at the City of Yelm’s request. 2. Records – the Owner shall keep records of the following; a. As-built plans and locations of installed stormwater facilities. b. Findings of fact from any exemption granted by the City of Yelm. c. Operation and maintenance requirements and records of inspection maintenance actions and frequencies d. Declaration of Covenant associated with the maintenance and operation of stormwater facilities. e. Any pertinent engineering reports. It is important to keep all of the stormwater system components free of debris and sediment, because if they get clogged the stormwater system will fail and will not meet water quality and flow control standards. Maintenance activities for the bioretention pond, infiltration facilities, flow control structures, conveyance pipes, and the catch basins include but are not limited to the actions listed in Appendix A. LDC Inc . Habitat for Humanity – Yelm Plat Operation and Maintenance Manual SECTION 6: VEGETATION MAINTENANCE Refer to the landscape plans for the planting schedule of the project site. SECTION 7: POLLUTION SOURCE CONTROL MEASURES 1. Avoid the activity or reduce its occurrence: If possible, avoid the activity or do it less frequently. Is there a substitute process or a different material available to get the job done? Can a larger run of a process be performed at one time, thus reducing the number of times per week or month it needs to be repeated? For instance, raw materials could be delivered close to the time of use instead of being stockpiled and exposed to the weather. Perhaps the site could avoid one solvent-washing step altogether. Apply lawn care chemicals following directions and only as needed. Many lawns are excessively fertilized. Do not apply herbicides right before it rains. Ecology or the Thurston County Department of Public Health and Social Services can provide pollution prevention assistance. 2. Move activities under shelter: Sometimes it is fairly easy to move an activity indoors out of the weather. The benefits of this are twofold; preventing runoff contamination, and providing for easier, more controlled cleanup if a spill occurs. An example would be unloading and storing barrels of chemicals inside a garage area instead of doing it outside. Please be aware that moving storage areas indoors may require installation of fire suppression equipment or other building modifications as required by the International Building Code (IBC), the International Fire Code or local ordinances. 3. Clean up spills quickly: Promptly contain and clean up solid and liquid pollutant leaks and spills on any exposed soil, vegetation, or paved area. Commercial spill kits are available, but readily available absorbents such as kitty litter also work well in many cases. Promptly repair or replace all leaking connections, pipes, hoses, valves, etc., which can contaminate stormwater. 4. Use less material: Don’t buy or use more material than you really need. This not only helps keep potential disposal, storage, and pollution problems to a minimum, but will probably save money, too. 5. Use the least toxic materials available: Investigate the use of materials that are less toxic than what is used now. Perhaps a caustictype detergent or a solvent could be replaced with a more environmentally friendly product. Such a change might allow the site to discharge process water to the sanitary sewer instead of paying for expensive disposal. Remember that even if using a biodegradable product, nothing but uncontaminated water is allowed to enter the stormwater drainage system. 6. Create and maintain vegetated areas near activity locations: Vegetation of various kinds can help filter pollutants out of stormwater, so it is advisable to route stormwater through vegetated areas located near the activity. For instance, many parking lots contain grassy islands, typically formed in a “hump.” By creating those islands as LDC Inc . Habitat for Humanity – Yelm Plat Operation and Maintenance Manual depressions instead of humps, they can be used to treat runoff from the parking lot or roof. Also, don’t forget the erosion control benefits of vegetation at a site. 7. Locate activities as far as possible from surface drainage paths: Activities located as far as possible from known drainage paths, ditches, streams, other water bodies, and storm drains will be less likely to pollute, since it will take longer for material to reach the drainage feature. This gives more time to react to a spill, or if it is a “housekeeping” issue, may protect the local waters long enough for you to clean up the area around the activity. Don’t forget that groundwater protection is important throughout the region, no matter where the activity is located, so the actions taken on your site on a day-to-day basis are always important, even in dry weather. 8. Maintain stormwater drainage systems Pollutants can concentrate over time in storm drainage structures such as catch basins, ditches, and storm drains. When a large storm event occurs, it can mobilize these pollutants and carry them to receiving waters. Develop and implement maintenance practices, inspections, and schedules for treatment facilities (e.g., detention ponds, oil/water separators, vegetated swales). Clean oils, debris, sludge, etc., from all BMP systems regularly, including catch basins, settling/detention basins, oil/water separators, boomed areas, and conveyance systems, to prevent the contamination of stormwater. Promptly repair or replace all substantially cracked or otherwise damaged paved secondary containment, high-intensity parking, and any other drainage areas that are subjected to pollutant material leaks or spills. Also repair or replace all leaking connections, pipes, hoses, valves, etc., which can contaminate stormwater. Requirements for cleaning stormwater facilities are discussed in Volume IV of the 2019 Ecology Manual, specifically BMP S417. Maintenance standards can be found in Chapter 3, Appendix 3B. 9. Reduce, reuse, and recycle as much as possible Always look for ways to recycle instead of just disposing. This can save money as well as keep both hazardous and non-hazardous materials out of the landfills. Learn more about other businesses that have made process changes allowing recycling of chemicals by calling Ecology at 1-800-RECYCLE and requesting publications No. 92-45 and No. 90-22. Another unique recycling opportunity for businesses is available through the Industrial Materials Exchange. This free service acts as a waste or surplus “matchmaker,” helping one company’s waste become another company’s asset. For instance, waste vegetable oil can become biofuel for another business. Call Industrial Materials Exchange at (206) 625-6232 to list potentially usable solid or chemical waste in their publication. 10. Be an advocate for stormwater pollution prevention Help friends, neighbors, and business associates find ways to reduce stormwater pollution in their activities. Most people want clean water and do not pollute intentionally. Share your ideas and the BMPs in this chapter to get them thinking about how their everyday activities effect water quality. LDC Inc . Habitat for Humanity – Yelm Plat Operation and Maintenance Manual 11. Report problems We all must do our part to protect water, fish, wildlife, and our own health by implementing proper BMPs, and reporting water quality problems that we observe. Contact your jurisdiction about the department that should be contacted in case of a spill. You may also contact Ecology’s Southwest Regional Office at (360) 407-6300. 12. Provide oversight and training Assign one or more individuals at your place of business to be responsible for stormwater pollution control. Hold regular meetings to review the overall operation of BMPs. Establish responsibilities for inspections, operation and maintenance (O&M), documentation, and availability for emergency situations. Train all team members in the operation, maintenance, and inspection of BMPs and reporting procedures. 13. Dust control Sweep paved material handling and storage areas regularly as needed, to collect and dispose of dust and debris that could contaminate stormwater. Do not hose down pollutants from any area to the ground, storm drain, conveyance ditch, or receiving water. 14. Eliminate illicit connections An illicit connection is formally defined in the city’s NPDES Municipal Stormwater Permit, but generally includes any connection to the city stormwater system that is not intended, permitted, or used for collecting and conveying stormwater. A common problem with the stormwater drainage system for most communities is the existence of illicit connections of wastewater to the storm drainage system. Wastewater other than stormwater runoff, such as wash water, must be discharged to a wastewater collection system, and may not be discharged to a storm drainage system (the storm drainage system does not drain to a wastewater treatment plant). Many businesses and residences have internal building drains, sump overflows, process wastewater discharges, and even sanitary sewer and septic system pipes that were connected to the nearby storm drainage system in the past as a matter of course. All businesses and residences must examine their plumbing systems to determine if illicit connections exist. Any time it is found that toilets, sinks, appliances, showers and bathtubs, floor drains, industrial process waters, and/or other indoor activities are connected to the stormwater drainage system, these connections must be immediately rerouted to the sanitary or septic system, holding tanks, or a process treatment system. 15. Dispose of waste properly Every business and residence in the city must dispose of solid and liquid wastes and contaminated stormwater properly. There are generally four options for disposal depending on the type of materials.

Habitat for Humanity – Yelm Plat Operation and Maintenance Manual APPENDIX A OPERATIONS AND MAINTENANCE STANDARDS Appendix V-A: BMP Maintenance Tables Ecology intends the facility-specific maintenance standards contained in this section to be conditions for determining if maintenance actions are required as identified through in spection. Recognizing that Permittees have limited maintenance funds and time, Ecology does not require that a Permittee perform all these maintenance activities on all their stormwater BMPs. We leav e the determination of importance of each maintenance activity and its priority within  the stormwater program to the Permittee. We do expect, however, that sufficient maintenance will occur to ensur e that the BMPs continue to operate as designed to protect ground and surface waters. Ecology doesn’t intend that these measures identify the facility's required condition at all times between inspec tions. In other words, exceedance of these conditions at any time between inspections and/or maintenance does not automatically constitute a violation of these standards. However, based upon inspecti on observations, the Permittee shall adjust inspection and maintenance schedules to minimize the length of time that a facility is in a condition that  requires a maintenance action. Maintenance Component Defect Conditions When Maintenance Is Needed Results Expected When Maintenance Is Performed General Trash & Debris   Any trash and debris which exceed 1 cubic feet per 1,000 sq uare feet. In general, there  should be no visual evidence of dumping.  If less than threshold all trash and debris will be removed as part of next scheduled maintenance.

To prevent violations of surface water quality, groundwater quality, and sediment management standards. To eliminate the discharges of un-permitted process wastewater, domestic wastewater, non-contact cooling water and other illicit discharges to stormwater drainage systems. 1.2 About This Program All commercial and industrial properties and activities, including multi-family residential complexes (i.e. apartments, condominiums), non-residential special uses, and government facilities in the City of Yelm that have the potential to contribute pollutants to stormwater runoff or directly to receiving waters are required to implement stormwater pollution prevention source control measures. Stormwater runoff may seep into the ground, drain to a storm drain or a drainage ditch, or flow over the ground. Regardless of the way runoff leaves your site, it ends up in a stream river, lake, wetland, groundwater, or Puget Sound. All known, available and reasonable source control BMPs shall be applied to your site. Source control BMPs shall be selected, designed, and maintained in accordance with Volume IV of the Department of Ecology Stormwater Management Manual for Western Washington (SWMMWW). Many people believe that stormwater runoff is “clean” and does not harm water quality. This perception is understandable since the amount of pollution from any one place is not usually significant by itself. However, when all these small amounts are combined, they can cause significant pollution problems. Contaminated stormwater can negatively affect every water body it enters. Therefore, this plan provides detailed information to reduce the contamination of surface water, groundwater, and stormwater from your property and/or business. The federal Clean Water Act mandates that cities and counties control the quality of stormwater runoff. One way to achieve this is to implement pollution prevention measures on individual properties. By following the “Best Management Practices” for your business or stormwater management site as described in this program, you can do your part to protect our streams, groundwater, and Puget Sound. 1.3 What Are Best Management Practices? Best Management Practices (BMPs) are a set of activities designed to reduce stormwater pollution. BMPs are separated into two broad categories: source control and treatment. Applicable BMPs for your business have been selected from the most recent published edition of the Department of Ecology Stormwater Management Manual for Western Washington, Volume IV. 1.3.1 Source Control BMPs Source control BMPs prevent contaminants from entering stormwater runoff by controlling them at the source. Some source control BMPs are operational, meaning they are tasks or actions such as checking regularly for leaks and drips from equipment and vehicles, covering materials that have potential to add pollutants to surface water if rainwater comes in contact with the materials, and minimizing use of 5 pesticides, fertilizers, and insecticides. Other source control BMPs require use of a structure to prevent rainwater from contacting materials that will contaminate stormwater runoff such as providing a covered area or berm to prevent clean stormwater from entering work or storage areas. 1.3.2 Treatment BMPs In contrast, treatment BMPs are structures that treat stormwater to remove contaminants. Treatment BMPs typically require planning, engineering design, and construction. A stormwater treatment pond is an example of a treatment BMP. No treatment BMP is capable of removing 100 percent of the contaminants in stormwater and the less contaminant in the stormwater the more effective the treatment BMP is. Just because there is a stormwater collection system serving your property, it does not necessarily mean that the stormwater is treated. Many sites were developed prior to requirements to treat stormwater. Runoff from your property may go directly or indirectly to a stream or wetland without any treatment. This plan focuses on source control BMPs applicable to the routine practices of your business and/or property. 1.4 What is in This Document? This plan has been customized for your business and/or property relevant to operations that may occur. Changes to site use or types of activities that take place on your property may require an update to this program. The plan is divided as follows: Sections • Introduction • Your Stormwater Facilities • Principles of Pollution Prevention • General Source Control BMPs • Specific BMPs for Your Site • Implementing this Pollution Source Control Program Appendices • A – Commercial and Industrial Activities Worksheet • B – Applicable Facility Activity Sheets • C – Annual Report Checklist • D – Spill Control Plan (Not applicable) • E – Integrated Pest Management Plan (Applicable) 2.0 Your Stormwater Facilities Flow control is required for the proposed development and will be provided through the use of a bioretention pond in the west corner of the site and drywells for the proposed residences located on each individual lot. The proposed improvements are divided into four flow control basins. The majority of the on-site improvements are included in Basin 1. The stormwater runoff from the proposed internal road, sidewalks, and driveways will be collected and conveyed to the bioretention pond. The bioretention pond has been sized using the Western Washington Hydrology Model (WWHM 2012) to fully infiltrate and treat all of the stormwater runoff conveyed to it. Basin 2 consists of the stormwater runoff from the proposed buildings. Each lot will be responsible for fully infiltrating the stormwater runoff on each lot via a drywell. Basin 3 and Basin 4 consist of the existing frontage areas that cannot be collected and conveyed to a system on-site. The stormwater runoff from these basins will continue to use the City of Yelm stormwater conveyance system. 6 3.0 Principles of Pollution Prevention This section describes the 15 general principles of pollution prevention that every business owner should consider. Most of these practices are common sense, “housekeeping” types of solutions to pollution prevention. 1. Avoid the activity or reduce its occurrence Avoid potentially polluting activity or do it less frequently. Apply lawn/landscape care chemicals following directions and only as needed. Do not apply herbicides right before it rains. 2. Move the activity indoors Move a potentially polluting activity indoors out of the weather. This prevents runoff contamination and provides more control for a cleanup if a spill occurs. 3. Cleanup spills quickly Promptly contain and cleanup solid and liquid pollutant leaks and spills on exposed soil, vegetation, or paved areas. Use readily available absorbents such as kitty litter to absorb spills and then sweep up the material and dispose of it properly. Repair leaks on vehicles and equipment. 4. Use less material Do not buy or use more material than you really need. This not only helps keep potential disposal, storage and pollution problems to a minimum, but will probably save you money. 5. Use the least toxic materials available Investigate the use of materials that are less toxic. For example, replace a caustic-type detergent or solvent with a more environmentally friendly product. If you do switch to a biodegradable product, remember that only uncontaminated water is allowed to enter the stormwater drainage system. 6. Create and maintain vegetated areas near activity locations Vegetation can filter pollutants out of stormwater. Route stormwater from parking and work areas through vegetated areas. Remember that wastewater other than stormwater runoff, such as wash water, must be discharged to a wastewater collection system (sewer or septic system). 7. Locate activities as far as possible from surface drainage paths Locate activities away from storm drains, ditches, streams, and other water bodies to reduce the potential to pollute. It will take longer for material to reach the drainage features providing more time to react to a spill, or “housekeeping” issue and protect local waters long enough to cleanup. 8. Maintain stormwater drainage systems Pollutants concentrate over time in catch basins, ditches, and storm drains. When a storm event occurs, turbulent runoff can mobilize these pollutants and carry them to receiving waters. Perform regular maintenance on stormwater facilities to prevent this from occurring. 9. Reduce, reuse, and recycle as much as possible Look for ways to recycle. This saves money and keeps hazardous and non-hazardous materials out of landfills. Contact the City of Yelm Waste Resources division for more information on recycling opportunities in the City. 10. Be an advocate for stormwater pollution prevention Help friends, neighbors, and business associates find ways to reduce stormwater pollution in their activities. Most people want clean water and do not pollute intentionally. Share your ideas and the BMPs in this plan to get them thinking about how their everyday activities affect water quality. 7 11. Report problems We all must do our part to protect water, fish, wildlife, and our own health by implementing proper BMPs, and reporting water quality problems that we observe. Call the City of Yelm Public Works at 360 .458.8406 to report dumping to storm drains or ditches. 12. Provide oversight and training Talk to your employees, or if you are a landlord talk to your tenants, to ensure they understand the pollution prevention source control measures and BMPs described in this program. If you are a landlord, you are still responsible for the activities of your tenants. Monitor the activities of your tenants to ensure that they are carrying out the principles of this program. See Section 6.0 of this document regarding implementation of this program. 13. Dust control Sweep parking and storage areas regularly to collect and dispose of dust and debris that could contaminate stormwater. Do not hose down pollutants from any area to the ground, storm drain, conveyance ditch or any receiving water (stream, wetland, lake, etc.). Do not use oil or other petroleum products for dust control. Only light watering of dirt or gravel roads or parking areas should be conducted to prevent any runoff of stormwater from the surface. 14. Eliminate illicit connections Occasionally businesses have internal building drains, sump overflows, sump pumps, outdoor sinks and showers, and even sanitary sewer and septic system pipes that were inadvertently connected to the storm drainage system in the past. Examine the plumbing system for your business to determine if illicit connections exist. Toilets, sinks, appliances, showers, bathtubs, floor drains, industrial process waters, and other indoor activities found to be connected to the stormwater drainage system must be immediately rerouted to the sanitary sewer or septic system, holding tanks, or process treatment system. For assistance in methods to detect and eliminate illicit connections contact the City of Yelm Public Works. 15. Dispose of waste properly Every business and residence in City of Yelm must dispose of solid and liquid wastes and contaminated stormwater properly. There are generally four options for disposal depending on the type of materials. These options include: • Sanitary sewer and septic systems. • Recycling facilities • Municipal solid waste disposal facilities • Hazardous waste treatment, storage and disposal facilities. 8 4.0 General and Applicable (Mandatory) to All Sites Source Control Best Management Practices This section briefly summarizes source control BMPs and corrective actions that are applicable to all types of sites, not just your property and include both general source control BMPs and those that are applicable (mandatory) to all sites.

While not a comprehensive list of steps to implement this program, the following information will assist in using this document effectively. Inspection tasks, record keeping, and reporting should be completed in conjunction with your Stormwater Facility Maintenance Program, if applicable to your site. 6.1 Formation of a Pollution Prevention Team (S101) The person designated as Program Operator for the site or business shall be responsible for stormwater pollution control. The Program Operator – or their designee – will hold regular meetings with the team to review the overall operation of the BMPs in this program. The Program Operator will establish responsibilities for inspections, operation, maintenance, and for emergencies. The Program Operator will be responsible for training all team members and employees in the operation, maintenance, inspection of BMPs, and reporting procedures. The Program Operator will be the primary contact for the City of Yelm regarding this Pollution Source Control Program and its implementation. 6.2 Employee Training (S105) Training programs may be tailored as necessary by the Program Operator. At a minimum, all employees that work in pollutant source areas shall have training in: • Identifying pollutant sources • Understanding pollutant control measures and BMPs • Responding to spills • Pollutant handling practices that are environmentally acceptable. Particularly those related to vehicle/equipment liquids such as fuels, and vehicle/equipment cleaning. 6.3 Inspections (S106) Qualified personnel shall conduct visual inspections monthly. Inspectors shall make and maintain a record of each inspection on-site. Inspections shall: • Verify the accuracy of the pollutant source descriptions in this program. • Verify the performance of the stormwater operational and structural source controls and treatment BMPs. • Reflect current conditions on the site. • Include written observations of the presence of floating materials, suspended solids, oil and grease, discoloration, turbidity and odor in the stormwater discharges; in outside vehicle maintenance/repair; and liquid handling, and storage areas. In areas where acid or alkaline materials are handled or stored use a simple litmus or pH paper to identify those types of stormwater contaminants where needed. • Eliminate or obtain a permit for unpermitted non-stormwater discharges to storm drains or receiving waters, such as process wastewater and vehicle/equipment washwater. When site inspections warrant or activities on the site are no longer applicable to the BMPs found in this program, this Pollution Source Control Program document shall be revised by the Program Operator as necessary to comply with local, state, and federal water quality requirements. For assistance in revising your Pollution Source Control Program, contact City of Yelm Public Works for guidance. 15 15 6.4 Record Keeping (S107) Program Operators shall retain the following reports for five years: • Visual inspection reports which should include: o Time and date of the inspection o Locations inspected o Statement on status of compliance with your permit (if you hold a NPDES Permit with Washington State Department of Ecology) o Summary report of any remediation activities required o Name, title, and signature of person conducting the inspection • Reports on spills of oil or hazardous substances in greater than Reportable Quantities (Code of Federal Regulations Title 40 Parts 302.4 and 117). Report spills of the following: antifreeze, oil, gasoline, or diesel fuel, that cause: o A violation of the State of Washington's Water Quality Standards o A film, sheen, or discoloration of the waters of the State or adjoining shorelines o A sludge or emulsion to be deposited beneath the surface of the water or upon adjoining shorelines • To report a spill or to determine if a spill is a substance of a Reportable Quantity, call the Washington State Department of Ecology regional office and ask for an oil spill operations or a dangerous waste specialist: Northwest Region (425) 649-7000 Southwest Region (360) 407-6300 Eastern Region (509) 329-3400 Central Region (509) 575-2490 In addition, call the Washington Emergency Management Division at 1-800-258-5990 or 1-800OILS-911 AND the National Response Center at 1-800-424-8802. Also, refer to Emergency Spill Response in Washington State, Publication # 97-1165-CP. • Maintain records of all related pollutant control and pollutant generating activities such as training, materials purchased, material use and disposal, maintenance performed, etc. 16 APPENDIX A Commercial and Industrial Activities Worksheet This worksheet and the associated BMPs are organized by business activity. The goal of BMPs is to ensure that only uncontaminated stormwater is discharged into any stormwater drainage system. Complete the entire worksheet by checking the appropriate boxes for all activities that occur at your workplace. If you checked off any of the activities that are being performed outdoors or can drain to the stormwater drainage system, use the activity code on the worksheet to find the BMPs recommended for you in Volume IV of the Department of Ecology Stormwater Management Manual for Western Washington. If you perform an activity indoors and control all discharges from the activity (e.g., process water, washwater, lubricants, solvents, fugitive dust, granular material, blow down waste) so that no stormwater exposure occurs, you do not have to institute BMPs for that activity. If you have questions, please contact the City of Yelm Public Works at (360) 458-8406 or by email at pwd@ci.yelm.wa.us. They can provide assistance over the phone and at your business site.

That worksheet and the BMPs listed are organized by the different activities that businesses perform. Use the Activity Sheets in Volume IV of the Department of Ecology Stormwater Management Manual for Western Washington to prepare a summary of the applicable required and suggested BMPs for inclusion in Table 2 of this document. If you checked the column for activities performed outdoors, match the number from the worksheet to the activities listed in SWMMWW Volume IV, Section IV-1 to IV-7 to find the suggested BMPs you should implement. You may make photocopies of the applicable Activity Sheets and insert them in this section. Explanation of Required BMPs Every business in City of Yelm is required to use the BMPs described in the SWMMWW to control stormwater pollution. In some instances, there are BMPs mandated by various federal, state, or county laws. If you are subject to those laws and regulations via another permit or formal regulatory approval, you are encouraged, but not required to use additional BMPs to further protect water quality. The BMPs outlined in this section are focused on source control: that is, methods to prevent pollution from reaching stormwater in the first place. The use of source control BMPs is always the first line of defense in stormwater pollution prevention. 20 21 22 23 24 25 26 27 28 29 31 32 33 34 35 36 37 38 39 40 41 42 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 APPENDIX C Annual Report Checklist 62 SOURCE CONTROL ANNUAL REPORT CHECKLIST Your stormwater pollution prevention plan should be reviewed at least annually and updated as required.

The residents, owners and management of the buildings within the Habitat for Humanity – Yelm Plat development are responsible for the continued implementation and oversight of this plan because the facilities are located in a group A wellhead protection area and a subdivision with more than 10 lots in a Category I Aquifer Recharge Area. The intent of the IPMP is to provide residents, owners and managers with guidelines to govern pest control methods within the development. The major goals of the IPMP are two-fold: to provide a structured process for pest management and to minimize the amount of chemical application within the Habitat for Humanity – Yelm Plat properties by emphasizing prevention and encouraging non-chemical methods of pest control in an effort to protect the Group A wellhead. This approach will aid in minimizing adverse environmental impacts, primarily groundwater contamination of the water system. Effective pest management attempts to keep properly identified pest populations below a certain population or damage level, starting with the safest control methods. Successful implementation of the IPMP will require ongoing communication and cooperation between residents, owners, managers, employees and trained professionals. All employees will be given a copy of the IPMP for the Habitat for Humanity – Yelm Plat development, and management will also provide educational materials to inform employees on various aspects of pest management. The appropriate professional consultant(s) shall be retained when necessary to provide assistance in implementing the plan. 2.0 Pests Within this IPMP, a pest is defined as an unwanted plant, animal, disease, or organism intrusion into the development that is desired or required to be removed or controlled by the owners, management or the City of Yelm or Thurston County. Contact the Washington State University (WSU)/Thurston County Extension at 360-867-2189 or visit https://extension.wsu.edu/thurston/gardening/resources/ for more information. 3.0 Existing Site Location and Features The Habitat for Humanity – Yelm Plat project consists of dividing one 2.30-acre parcel into twenty-two residential lots. The site is located at 407 Longmire St NW. The project parcels are within the 5-year and 10-year wellhead protection area and in a group A public water supply well area, as well as a Category I critical aquifer recharge area (CARA). A Group A Public Water System is a water system that serves 15 or more connections, or an average of 25 or more persons per day for 60 or more days within a calendar year (WAR 246-290-020). Wellhead protection area means the surface and subsurface area surrounding a water well or well field, through which contaminants are reasonably likely to move toward and reach such well or well field within one, five and ten years, respectively. For Group A water systems, the wellhead protection area shall Habitat for Humanity – Yelm Plat Integrated Pest Management Plan Page 2 be the wellhead protection area identified in the approved water system plan, prepared according to the requirements of chapter 246-290 WAC, or an equivalent area accepted by the health officer (Title 24 WAC Critical Areas). An IPMP is important to protect nearby natural resources and sensitive areas such as groundwater for this site. Potential landscaping and pest control activities that could impact the quality of the sensitive groundwater include needless chemical applications, excess leached nutrients, fungicides, and herbicides. See sections below for additional guidance for mitigation. The site soils are identified by the Soil Conservation Service Soil Survey of Thurston County, Washington as Spanaway gravelly sandy loam which is classified as a type A soil. A geotechnical investigation was conducted by Landau Associates in July 2021 for the Habitat for Humanity Yelm Plat. Six test pits were conducted to depths of approximately 10 to 12 feet below ground surface. The soils generally encountered were a recessional outwash beneath about 9 inches of topsoil. The recessional outwash typically consisted of grayish-brown to brown, sandy gravel or gravelly sand with variable silt, cobble, and boulder content in a medium dense to dense condition. All six tests were terminated following moderate to severe caving and before reaching groundwater. The site was determined to have an infiltration rate of 6.4 inches per hour in the west corner of the site at test pit 5, where an infiltration pond is being proposed. Groundwater mounding is not of concern and the recommended groundwater elevation for designing infiltration BMPs is 20 ft below ground surface. The proposed Habitat for Humanity – Yelm Plat development will create both treatment and flow control facilities. The stormwater runoff from the proposed road, sidewalks, and driveways will be collected and conveyed to a bioretention pond where the stormwater runoff received enhanced treatment and fully infiltrates. The stormwater runoff from the proposed roof areas will be mitigated on each lot via drywells. 4.0 Management Area Objectives From the standpoint of an IPMP, there will be one management area for the parcel. Landscape professionals will likely be hired and along with the residents will maintain all areas within the Habitat for Humanity – Yelm Plat and provide pest inspections to ensure that these tasks are being performed regularly and thoroughly. 5.0 Control Methods There are five main methods for controlling pest populations: 1. Cultural Controls: Methods that require an understanding of the culture of individual plant species or turfgrasses. Adequate site preparation, efficient use of water, need for aeration, and timing, selection, and efficient use of fertilizers are all examples of cultural control methods. 2. Mechanical Controls : Methods that require labor-intensive actions such as mowing, hoeing, and hand weeding. Habitat for Humanity – Yelm Plat Integrated Pest Management Plan Page 3 3. Physical Controls : Methods that alter the site to prevent insect damage such as manual removal and destruction of pests, traps, and barriers. 4. Biological Controls : Methods include naturally occurring organisms such as predators and parasitoids, as well as naturally occurring and introduced microbial products. 5. Chemical Controls : Include insecticides, fungicides, herbicides, and other chemicals intended to control, prevent, or repel pests if used properly. The overlying theme of the IPMP is emphasis on prevention as the best and most efficient means of pest control. Prevention of potential pest problems is best accomplished through use of cultural controls. Mechanical and physical controls also aid in prevention by removing potential pests before populations can increase and spread. Chemical and biological control methods should be used as the last line of defense and should only be considered after other control methods have been exhausted. Oftentimes, chemical and biological controls do more harm than good by reducing both pest and beneficial organisms in the control process. Combinations of these methods can also prove useful depending upon the specific situation. It is important to state that this Integrated Pest Management Program does not attempt to eradicate a pest, since in most instances it is desirable to allow the pest to survive in lower numbers in order to maintain the presence of natural predators. 6.0 Implementation Strategies An IPMP is by nature dynamic and should change over time as specific control strategies within the community are implemented and evaluated. Ongoing development of an IPMP should involve periodic review of five principal components: 1. Prevention 2. Identification 3. Inspection 4. Thresholds for Control 5. Appropriate Control Actions These steps are further described below. 6.1 Prevention Prevention provides the best line of defense against potential pest problems and is the least costly. Many pest problems in landscapes can be avoided by selecting plants with known pest resistance and avoiding those plants that are known to be susceptible. To minimize the use of pesticides and fertilizers, at least 75% native species and/or drought tolerant plants shall be planted. Selecting indigenous plants provides the owner with an additional line of defense against pests, since most of these plants are resistant to local pest populations. The Thurston County Local Hazardous Waste Program has prepared a Habitat for Humanity – Yelm Plat Integrated Pest Management Plan Page 4 native and drought tolerant plant list that is available at the Thurston County courthouse and the WSU Cooperative Extension Office (360) 867-2189. Other elements such as proper soil preparation, planting, irrigation, and mulching techniques discourage the presence of pest populations. Proper site construction and soil preparation by the developer is required prior to landscaping such as stockpiling topsoil on site then mixing in 4-6” STA certified compost to reincorporate into landscaped area, importance of landscape design and proper choice of plants which are adapted for the site conditions, proper planting techniques, and benefits of the use of mulch and weed barriers in landscape beds. Consider compost and bark application and the percentage of native plants incorporated in the initial plan. Many symptoms resulting from inadequate prevention measures are incorrectly attributed to the presence of pests. This can result in needless chemical applications that fail to address the actual problem and contribute to groundwater contamination. 6.2 Identification Proper identification of the pest or symptom affecting a given plant or plants is an essential step before determining the proper control action. Owners and managers should take responsibility to familiarize themselves with common indicators of pest problems and/or consult with a professional. There are several professional resources within the community to aid in the identification of pests. Landscape contractors such as ecoPro Certified Sustainable Landscape Professionals, nursery professionals, and the Master Gardeners at the WSU Cooperative Extension Office are all valuable resources that can identify pests and recommend appropriate control methods based upon their expertise. Although they should not be relied upon alone, reference books also provide another valuable resource in diagnosing or identifying a potential pest problem. Before applying any control methods, the owner, manager or professional must determine whether action is needed or is likely to be effective. Affected plants should be evaluated in terms of their value in the landscape. It is possible that the value of the plant is much less important and could be replaced with less effort than chemical application. It may be too late for a control to be effective, or the problem may be minor. In some situations, no action may be the best alternative. If action is needed, control methods can be used individually or in combination. Priority should always be given to non-chemical control methods. 6.3 Inspection Owners and managers should establish a schedule for systematically surveying their landscape for pests and damage evidence. This is an important activity and should be performed on a regular basis. By performing regular inspections, potential pest problems are controlled much easier than if the given pest has time to propagate and spread to other locations. It is recommended that a landscape professional be hired to regularly inspect landscape areas throughout the properties. Inspections should be more frequent in Spring and Summer months, which are the principal times for pest activity. Habitat for Humanity – Yelm Plat Integrated Pest Management Plan Page 5 6.4 Thresholds for Control Many pests do not actually kill plants, but simply make them unsightly. Landscaped areas will be maintained by a professional with the ability to provide an assessment of the existing state of the area and recommend management practices for the future. Such professionals can recommend the point at which some level of control should be taken. Knowing when a plant is approaching such a threshold may influence its treatment as well, since the problems are best treated at a particular time of year, or by a particular combination of controls. 6.5 Appropriate Control Actions Determining the success of a given treatment is essential in any modification of the IPMP. Comprehensive records shall be kept by the chosen professional. Complete records shall be kept for all treatment strategies in order to evaluate both short- and long-term success. Information to be recorded will include: • Identification of the pest • Location and size of affected areas • Recent weather including rainfall and temperature • Previous control methods • Control method to be implemented • Dates of implementation • Observed changes in condition after treatment Such detailed record-keeping will aid subsequent landscape professionals in fine-tuning treatment strategies. 7.0 Recommended BMPS Adequate site preparation is essential for the successful implementation of the IPMP. Upper layers of topsoil should be removed from foundation and road areas and stockpiled. This topsoil may then be reapplied to landscape areas as needed. In areas with little or no topsoil, soil amendments such as compost of well-aged manure should be added in a layer between 6 and 12 inches thick. This organic material should then be tilled into the soil thoroughly. The added organic material will serve to enrich the nutrient value of the soil, retain moisture, and filter impurities. After landscape is installed, the beds will be covered with 2-4” of compost. It is suggested that the beds receive additional compost or bark annually to retain soil moisture, provide nutrients, and help prevent weed growth. In areas with existing noxious weed species such as Scotch broom and Himalayan blackberry, plants will be removed to an off-site dump. These plants will be mechanically pulled prior to excavation to remove as much of the below ground root system as possible. Contractors conducting site work should be mindful of cleaning their equipment prior to completing their work to avoid the spread of noxious weeds from site to site. 8.0 Irrigation Practices Excess watering accelerates the movement of fertilizers and chemical residues through the soil before plants can fully benefit and can contribute to the presence of pests. Habitat for Humanity – Yelm Plat Integrated Pest Management Plan Page 6 Water requirements vary due to a variety of factors. Lawn irrigation systems should be designed to supply no more than a total of 1 inch of water per week (including rain). An evaluation of the soil type should determine the frequency the lawn should be irrigated (two to three times a week for sandy soil or once a week for soil with more clay). After plants are established, readjust the irrigation system water frequency to account for deeper root systems. After a watering schedule has been established, it is useful to remove a shovel full of soil between waterings and inspect the depth of watering being achieved. Soils that are excessively wet beyond plant root zones could benefit from less water and soils that remain excessively dry following watering may benefit from adding organic material that absorbs water. As a rule of thumb, watering schedules should be less frequent but with longer run times. • Irrigation systems should be properly adjusted to water plants exclusively at a rate of 1” per week and adjusted to include rainfall. • Watering should occur during early morning hours to reduce evaporative losses and minimize fungal problems in turfgrasses. • During extreme drought conditions, watering will be restricted to priority plantings such as trees and shrubs. Irrigation systems must be well adjusted in applying water only to plants, not to pavement. After plants are established, readjust the irrigation system watering frequency to account for deeper root systems. 9.0 Fertilizing Options All plants need a supply of nutrients in addition to light, air and water for proper growth and development. Three main elements are responsible for proper plant development: nitrogen, phosphorus and potassium. Nitrogen Nitrogen is the element needed in the greatest quantity by plants. All nitrogen used by plants comes from combinations of organic matter, air, and commercial fertilizers and is responsible for most of the visible growth of plants. Nitrogen is found in forms that are either immediately available to plants (soluble or quick release forms) or not immediately available to plants (insoluble or slow release). Due to the chemical nature of nitrogen, it is leached quickly and readily from the soil. Phosphorus Phosphorus is associated with root development in plants. The most effective method of applying a fertilizer containing phosphate is to concentrate it within the root zone. It is less mobile in most soils than nitrogen, but should be used sparingly to avoid overloading the soil or water with excess nutrients. In Washington State, phosphorus is not permitted in lawn fertilizer due to water pollution concerns (RCW 15.54.500). Habitat for Humanity – Yelm Plat Integrated Pest Management Plan Page 7 Potassium Potassium is an element also commonly referred to as potash. Potassium aids in the flowering and fruiting of appropriate plants and aids in a plant’s ability to withstand stress. Potassium can also be leached from the soil like nitrogen and phosphorus. Both organic mulches and commercial fertilizers contain these elements, as well as several trace elements required by plants in much smaller quantities. Excess irrigation and high rainfall can leach these nutrients from the soil. 9.1 Organic Mulches Organic mulches such as barks and composts provide several advantages when compared to commercial fertilizers. The first advantage is that organic mulches provide a well-rounded nutrient source for most plant material and take the guesswork out of using the “right” combination of synthetic fertilizers. These mulches can be applied in the Fall and/or Spring and release nutrients slowly to plants as they break down. This provides most plants with a year-round nutrient source. As organic mulches decompose, they add structure to soils and provide greater moisture retention and help to regulate temperature extremes within the soil. The other benefit is that organic mulches slow the movement of water through the soil by their ability to absorb and retain water. For these reasons, organic mulches are the most preferable means of increasing nutrient levels within soil. 9.2 Fertilizers Regardless of the specific types, fertilizers should only be applied when it becomes evident that a nutrient deficiency exists. Thurston Conservation District offers soil testing services and can recommend fertilizing rates and timing. Organic mulches will provide adequate quantities of nutrients to plants in the majority of situations and should be applied before fertilizers are considered. Fertilizer applications should not be used during the high rainfall winter season. Of the commonly applied fertilizers, application of excess soluble nitrogen constitutes the most serious risk to groundwater supplies. Commercial fertilizers come in a variety of formulas and forms. These fertilizers usually come in dry or liquid forms that are applied directly to the surface of the soil. These fertilizers are available in quick and slow-release formulas. Slow-release fertilizers are less likely to cause water pollution problems, an important consideration due to the site location in a wellhead protection area. Quick release fertilizers contain forms of nitrogen phosphorus and potassium that are readily available to plants. The advantage of this type of fertilizer is that a known nutrient deficiency can be corrected relatively quickly. Only slow-release fertilizers shall be applied for the life of the development at a maximum amount of 4 lbs. of nitrate as nitrogen annually and no more than 1 lb. per application for every 1,000 square feet of turf grass. Only fertilizer formulas with a minimum of 50% water insoluble form of nitrogen are permitted for use. Approved water insoluble forms of nitrogen include sulfur and/of polymer coated fertilizers, Isobutylidene Diurea (IBDU), Methylene Urea and Ureform, and organic fertilizers registered with Washington Department of Agriculture. (City of Olympia Critical Areas Ordinance Chapter 18.32.225) These types of fertilizers migrate quickly through the soil and provide little or no benefit to the plant if excess water is applied. Groundwater Habitat for Humanity – Yelm Plat Integrated Pest Management Plan Page 8 supplies may be contaminated by readily leached nutrients. It is recommended that quick release formulas be applied during periods of active plant growth and only when a nutrient deficiency can be determined. In contrast, slow-release fertilizers are applied as infrequently as once a year, ideally at the end of the rainy season. These fertilizers continuously break down, providing nutrients to plants year-round. For this reason, it is much more difficult for slow-release fertilizers to migrate through soil into the groundwater. 9.3 Application Guidelines The following guidelines should be utilized when considering use of commercial fertilizers: • Avoid needless applications of fertilizer. For lawns, mulching mowers return cut grass to the ground and can provide up to one-third of the entire nitrogen requirement of the lawn. When fertilizing is appropriate, avoid heavy applications of quick release fertilizers, especially in lawn areas. Rather, consider the use of a natural lawn fertilizer. Natural lawn fertilizers are slow-release, require fewer applications, and provide more uniform growth. • In lawn areas, apply lighter rates of fertilizer more often. This practice is much more effective than applying heavy rates less often. As an example, one pound of soluble nitrogen per 1,000 square feet applied once a month poses less risk to groundwater than two pounds of soluble nitrogen per 1,000 square feet applied every two months. • To fertilize a lawn properly, it is important to first determine the square footage of the lawn area to be fertilized. Once the square footage of lawn areas has been established, a good rule of thumb is to apply one- to four pounds of nitrogen per 1,000 square feet of lawn per year. It is recommended that lawn fertilizing be applied four times a year during the months of April, June, September and November. As a guideline, no more than one-half pound of soluble nitrogen per 1,000 square feet should be applied in any single application. • It is possible to maintain a healthy lawn by using a natural lawn fertilizer once a year in September. If fertilizing twice a year, an additional application should be made in May. • Avoid over-watering lawns immediately after applying fertilizer. A preferred alternative is to irrigate the lawn thoroughly a day or two before fertilizing and water briefly after application – just enough to wash the fertilizer off the leaves and into the soil. • Do not use “weed and feed” type fertilizers, which contain pre-emergent herbicides, on lawn areas. Habitat for Humanity – Yelm Plat Integrated Pest Management Plan Page 9 10.0 Weed Control Mechanical and cultural control methods are the preferred means of weed control within the Habitat for Humanity – Yelm Plat development. These methods include combinations of hand pulling, tilling, installation of weed barriers, and application of organic mulch. These control methods are preferable to using herbicides, since herbicides may harm desirable plants and contaminate groundwater supplies. Chemical weed control is appropriate only in situations where mechanical and cultural means of control have been proven ineffective. If chemical weed control becomes appropriate, the following guidelines should be followed: • Use www.GrowSmartGrowSafe.org to help select the least hazardous pesticide if needed. Do not use products rated high and moderate hazard for water pollution due to the location in a wellhead protection area. Products that are effective and environmentally friendly should be selected. • Applications should be timed to provide for best results. Product label directions must be followed. • Applications should be made during windless periods at least four hours before probable rainfall, and early in the morning before the day heats up. • “Weed and feed” type fertilizers which contain pre-emergent herbicides shall not be used on lawn areas. • Use of herbicides must be recommended and applied by a licensed professional. 11.0 Fungicides Most fungi occupy areas with very specific environmental conditions. The progression of their life cycles is also very specific. For these reasons, fungicides should not be applied to vegetation until a professional has diagnosed the presence of a fungal infestation. The timing of watering can reduce many fungal infestations of plant foliage. Watering in the early morning will allow water standing on leaf surfaces to evaporate during the day and prevents the propagation of many leaf fungi. Careful attention to soil moisture levels can reduce the presence of fungi in the soil. Like other plant care chemicals, fungicides can also contribute to groundwater contamination. Once a professional has identified a fungus is present, a recommended treatment program, which may or may not involve fungicides, can be implemented and evaluated for effectiveness. Any use of chemicals shall be documented. See www.GrowSmartGrowSafe.org for the least toxic fungicides that should be applied to those plants or turf areas where problems exist. 12.0 Insecticides Insecticides should only be used when the level of infestation poses a threat to the life of the plant. Proper identification of the insect is the first step in controlling the problem. There are many beneficial insects which can help with pest control. See pictures of beneficial insects and strategies to help them to thrive in your landscape at www.GrowSmartGrowSafe.org. By identifying the insect, the professional can explore cultural means of controlling the insect by modifying the environment that may favor its Habitat for Humanity – Yelm Plat Integrated Pest Management Plan Page 10 presence. If insecticide application is recommended, it should begin with less toxic products. Use www.GrowSmartGrowSafe.org to help select the least hazardous pesticide if needed. Do not use products rated high and moderate hazard for water pollution due to the location in a wellhead protection area. Most insecticides are not specific. When applied, these insecticides don’t distinguish between a pest and a beneficial insect, and, for this reason, often do more harm than good. Insecticidal soaps are effective against a variety of insects and should be used carefully and sparingly for the same reason. The advantage of insecticidal soaps is that they are safer for the environment when compared to their counterparts. See pictures of beneficial insects and strategies to help them to thrive in your landscape at www.GrowSmartGrowSafe.org. 13.0 Chemical Application Practice Any outbreaks of fungal disease or insect infestation should be recorded and subsequently monitored to see if the outbreak increases. A period of three weeks should be allowed after any pesticide application to monitor the effect of the application. Pesticide applications should not be made at a higher frequency than once every three weeks. Treated areas will be posted to notify residents of the application of pesticides. Any professional consultant or employee who applies pesticides shall be licensed by the Washington State Department of Agriculture as a Public Pesticide Operator or Public Pest Control Consultant. The HazoHouse is recommended for free disposal of unused chemicals for Thurston County residents located at 2420 Hogum Bay Road NE in Lacey. 14.0 Products to Avoid All recommendations in this IPMP regarding use of chemicals must also be followed by landscape professionals working within the Habitat for Humanity – Yelm Plat development. Professionals will be required to adhere to this IPMP regardless of their possession of a state pesticide applicator’s license with legal ability to handle restricted pesticides. Landscape contractors will avoid materials described herein when working within the Habitat for Humanity – Yelm Plat development. A number of pesticides listed in the EPA National Pesticide Survey’s Leach List (1998) are unrestricted chemicals. These have high potential for leaching into groundwater. The use of the following common pesticides on the EPA list, and the use of any other “leacher” is not permitted in the community. Product labels should be consulted to determine whether these chemicals are present: • Acephate • Amitrol • Altrazine • Baygon • Bentazon • Carbaryl • Chloropyrifos • 2,4-D • DDDVP • Diazinon • 1,2-Dichloropropene • Cis-1,3-Dichloropropene Habitat for Humanity – Yelm Plat Integrated Pest Management Plan Page 11 • Trans-1,3-Dichloropropene • Dieldrin • Dicamba • Picloram • Pramitol • Simazine • 2,4,5-T • Triclopyramine 15.0 Storage and Handling of Chemicals Generally, all landscape maintenance chemicals are toxic and should be handled with care. All label requirements must be followed and only those chemicals recommended and approved for controlling the pest should be used. The following policies shall be followed in the community: • Wear protective clothing when mixing and applying chemicals. • Store chemicals in a dry place inaccessible to children, pets, or desirable organisms. • Keep containers well marked and tightly closed. • Save empty containers for disposal at a hazardous waste collection center. 16.0 Hazardous Material Use, Storage and Disposal Cover, containment, and protection from vandalism shall be provided for all chemicals, liquid products, petroleum products, and non-inert wastes present on the site (see Chapter 173-304 WAC for the definition of inert waste). Maintenance and repair of heavy equipment and vehicles involving oil changes, hydraulic system drain down, solvent and de-greasing cleaning operations, fuel tank drain down and removal, and other activities which may result in discharge or spillage of pollutants to the ground or into stormwater runoff must be conducted using spill prevention measures, such as drip pans. Contaminated surfaces shall be cleaned immediately following any discharge or spill incident. Spills should be reported to 911. Emergency repairs may be performed on-site using temporary plastic placed beneath and, if raining, over the vehicle. Application of agricultural chemicals, including fertilizers and pesticides, shall be conducted in a manner and at application rates that will not result in loss of chemical to stormwater runoff. Manufacturers’ recommendations shall be followed for application rates and procedures. Employees and residents are advised to avoid skin contact with hazardous materials such as oil, pesticides and household solvents and to wear gloves and use kitty litter or sawdust to absorb spills. All hazardous materials must be stored in water-tight containers and taken to the Hazo House at the Thurston County Waste and Recovery Center at 2420 Hogum Bay Road NE in Lacey. Hazo House is open daily from 8:00 a.m. – 4:45 p.m. and is free for Thurston County residents, businesses must register and pay a fee. Habitat for Humanity – Yelm Plat Integrated Pest Management Plan Page 12 17.0 Monitoring As noted above, detailed record keeping is valuable in assessing the success of a particular IPMP treatment. Landscape professionals working at the Habitat for Humanity – Yelm Plat development are required by law to keep careful records of chemical use. Records of pesticide applications are required to be kept for a minimum of 20 years and will include: • Date and time of pesticide application; • Specific location of application; • Purpose of application (target species); • Material, lot number, EPA registration number, amount, rate, and concentration used; • Method of application; • Temperature, wind speed and direction, weather conditions; • Applicator’s name and operator’s license number; • Evaluation of results. 18.0 IPMP Amendments Since a management plan can only be as effective as its constituent elements, it may be necessary to modify those elements as environmental factors or site-specific conditions dictate. Such changes may be necessary to better direct pest management efforts as well as modify procedural directives identified in the IPMP. Any proposed changes to the IPMP will be submitted to the City of Yelm for review and approval prior to implementation.

Discharge to on-site sewage disposal, or, if acceptable by the local sewer authority, discharge to sanitary sewer. * Ecology’s Hazardous Waste Program developed this information. The Hazardous Waste Service Directory is now available online at: http://apps.ecy.wa.gov/hwsd/default.htm 84 Appendix IV-E: Regulatory Requirements That Impact Stormwater Programs R.1 Stormwater Discharges to Public Sanitary Sewers, Septic Systems, Dead-End Sumps, and Industrial Waste Treatment Systems Stormwater Discharges to Sanitary Sewers. Discharging stormwater to a public sanitary sewer is normally prohibited, as this tends to overload the sewage treatment plant during storm events when flows are already high. Direct discharge of relatively uncontaminated or treated stormwater from businesses typically poses less of a threat to the environment than pass through of solids due to “wash out” at the sewage treatment plant during storm events. Such discharges require the approval of the local Sewer Authority if the Department of Ecology (Ecology) has delegated the authority to set pretreatment requirements. If the Sewer Authority has not received such authority, the business or public agency that wishes to discharge stormwater to the sanitary sewer must also apply for a State Waste Discharge Permit. In setting pretreatment requirements, the local Sewer Authority or Ecology must operate within state regulations (Chapter 173-216 WAC – State Waste Water Discharge Permit Program) which in turn must comply with federal regulations (40 CFR Part 403.5 – National Pretreatment). These regulations specifically prohibit discharge of any materials which: • Pass through the municipal treatment plant untreated or interfere with its operation. • Create a fire or explosion hazard, including, but not limited to, waste-streams with a closed cup flash point of less than 140 degrees Fahrenheit or 60 degrees Centigrade using the test methods specified in 40 CFR 261.21. • Will cause corrosive structural damage to the Publicly Owned Treatment Works (POTW), but in no case Discharges with pH lower than 5.0, or greater than 11, unless the works is specifically designed to accommodate such Discharges; and the discharge authorized by a permit issued under Chapter 173-216 WAC. (See WAC 173-216-060 (2) (iv)). • Solid or viscous pollutants in amounts that will cause obstruction to the flow in the POTW resulting in interference. • Heat in amounts that will inhibit biological activity in the POTW resulting in interference, but in no case heat in such quantities that the temperature at the POTW Treatment Plant exceeds 40 degrees Centigrade (104 degrees Fahrenheit) unless the system is specifically designed to accommodate such discharge, and the discharge is authorized by a permit under Ch 173-216 WAC. (See WAC 173-216-060 (2) (v)). • Petroleum oil, nonbiodegradable cutting oil or products of mineral oil origin in amounts that will cause interference or pass through the treatment plant. • Pollutants that result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems. • Any trucked or hauled pollutants, except at discharge points designated by the POTW. • Any discharge which would violate the dangerous waste regulations, Chapter 173-303 WAC (see WAC 173-216-060(1)). 85 • Any of the following discharges, unless approved by the department under extraordinary circumstances, such as lack of direct discharge alternatives due to combined sewer service or need to augment sewage flows due to septic conditions: (WAC 173-216-060(2)(vii)): − Noncontact cooling water in significant volumes. − Stormwater, and other direct inflow sources. − Wastewater significantly affecting system hydraulic loading, which do not require treatment or would not be afforded a significant degree of treatment by the system. Discharges of stormwater authorized under Chapter 173-216 WAC, typically limit flows entering the sanitary sewer based on the available hydraulic capacity of the collection system or the treatment plant by the combined flow of sanitary sewage and stormwater. The allowable concentrations of particular materials such as metals and grease vary with the particular sewer system. Discharges must comply with all local government limits. Please contact both the POTW and the regional water quality program to find out what discharge limits apply to a particular sewerage system. Stormwater Discharges to an Industrial Waste Treatment System: Operators may process treatment to dispose of polluted stormwater depending on the NPDES permit constraints of the particular business. Stormwater Discharges to Dead-end Sumps: Do not discharge substances that causes a violation of water quality standards to a septic system, surface water, or ground water. If a sanitary or industrial wastewater treatment system is not available, an alternative is the use of a dead-end sump. Sumps are tanks with drains that can be periodically pumped for appropriate disposal. Depending on the composition of the waste, it may or may not be considered Dangerous Waste. For more information on disposal requirements for sumps, see Step By Step: Fact Sheets for Hazardous Waste Generators, publication #91-12, available from Ecology's Regional Offices. R.2 Uniform Fire Code Requirements Storage of flammable, ignitable, and reactive chemicals and materials must comply with the stricter of local zoning codes, local fire codes, the Uniform Fire Code, Uniform Fire Code standards or the National Electric Code. R.3 Ecology Requirements for Generators of Dangerous Wastes The State's Dangerous Waste Regulations (Chapter 173-303 WAC) cover accumulation, storage, transportation, treatment and disposal of dangerous wastes. Of interest to this manual are those businesses or public agencies that accumulate the waste at their building until taken from the site by a contract hauler. For more information on applicable requirements for dangerous wastes, see Step By Step: Fact Sheets for Hazardous Waste Generators, publication #91-12, available from Ecology's Regional Offices. R.4 Standards for Solid Waste Containers Standards for solid waste containers are identified in WAC 173-350-300, On-site Storage, Collection, and Transportation Standards. 86 R.5 Coast Guard Requirements For Marine Transfer of Petroleum Products Federal regulations 33 CFR Parts 153, 154 and 155 cover, respectively, general requirements on spill response, spill prevention at marine transfer facilities, and spill prevention for vessels. These regulations specify technical requirements for transfer hoses, loading arms, closure, and monitoring devices. The regulations also cover small discharge containment: they require the use of “fixed catchments, curbing, and other fixed means” at each hose handling and loading arm area and each hose connection manifold area. Operators can use portable containment in exceptional situations where fixed containment is not feasible. The capacity of the containment area varies from the volume of 1 to 4 barrels depending on the size of the transfer hoses. The regulations also require an operations plan and specify its general contents. The plan shall describe the responsibilities of personnel, nature of the facility, hours of operation, sizes and numbers of vessels using the facility, nature of the cargo, procedures if spills occur, and petroleum transfer procedures. The plan must also include a description and location of equipment for monitoring, containment, and fire fighting. See also, NFPA 30A Automotive and Marine Service Station Code, American National Standard Institute and the National Fire Protection Association. R.6 Washington State/Federal Emergency Spill Cleanup Requirements Washington State Requirements: The Oil and Hazardous Substance Spills Act of 1990 and the Oil Spill Prevention and Response Act of 1991 (Chapter 90.56 RCW) authorized Ecology to develop effective oil spill response regulations. The Facility Contingency Plan and response Contractor Standards (Chapter 173-182 WAC): This Ecology regulation applies to all oil handling facilities (including pipelines) that are on or near navigable waters and transfer bulk oil by tank, ship, or pipeline. It contains the following elements: − Standards for contingency plan content − Procedures to determine the adequacy of contingency plans − Requirements for periodic review − Standards for cleanup and containment contractors The Oil Handling Training and Certification Rule (Chapter 173-180 WAC) establishes oil spill training and certification requirements for key facility personnel including applicable contractors involved in oil handling, transfer, storage, and monitoring operations. In accordance with WAC 173-303-350 of Ecology’s Dangerous Waste Regulations, generators of dangerous wastes must have a Contingency Plan that includes: − Actions to be taken in the event of spill − Descriptions of arrangements with local agencies − The name of the owner's Emergency Coordinator − A list of emergency equipment available − An evaluation plan for business personnel For more information on disposal requirements for solid and dangerous wastes, see Step By Step: Fact Sheets for Hazardous Waste Generators, publication #91-12, available from Ecology's Regional Offices. 87 Federal Requirements: The Oil Pollution Act of 1990 is a comprehensive federal law that addresses marine oil spill issues including contingency plans, financial responsibility, marine safety regulations, etc. Spill Prevention Control and Countermeasure (SPCC) Plans: Federal Regulations require that owners or operators of facilities engaged in drilling, producing, gathering, storing, processing, refining, transferring, or consuming oil and oil products are required to have a Spill Prevention and Control Plan (SPCC), provided that the facility is non-transportation related; and, that the above-ground storage of a single container is in excess of 660 gallons, or an aggregate capacity greater than 1,320 gallons, or a total below-ground capacity in excess of 42,000 gallons. The Plan must: − Be well thought out in accordance with good engineering; − Achieve three objectives - prevent spills, contain a spill that occurs, and clean up the spill; − Identify the name, location, owner, and type of facility; − Include the date of initial operation and oil spill history; − Name the designated person responsible; − Show evidence of approval and certification by the person in authority; and − Contain a facility analysis. R.7 WSDA Pesticide Regulations The Washington State Department of Agriculture (WSDA) administers pesticide laws, under the Washington Pesticide Control Act (Chapter 15.58 RCW), Washington Pesticide Application Act (Chapter 17.21 RCW), and regulations under Chapter 16-228 WAC. The requirements relevant to water quality protection are: Licenses are required for persons who apply pesticides except: − People who use general-use pesticides on their own or their employer's property; − Grounds maintenance people using only general-use pesticides on an occasional basis not amounting to a regular occupation; − Governmental employees who apply general-use pesticides without utilizing any kind of motorized or pressurized apparatus; − Employees of a commercial applicator or a government agency who are under direct on-site supervision by a licensed applicator. Licensed applicators must undergo 40 hours of continuing education to keep their license. No person shall pollute streams, lakes, or other water supplies while loading, mixing or applying pesticides. No person shall transport, handle, store, load, apply, or dispose of any pesticide, pesticide container, or apparatus in such a manner as to pollute water supplies or waterways, or cause damage or injury to land, including humans, desirable plants, and animals. For more information on pesticide application and disposal requirements the following publications may be useful: • “Hazardous Waste Pesticides: A Guide for Growers, Applicators, Consultants and Dealers,” Ecology Publication #89-41, August 1989, available from Ecology’s Regional Offices. 88 • “Suspended, Canceled and Restricted Pesticides,” EPA, available from the EPA Region 10 Office in Seattle. • “Best Management Practices for Agricultural Chemicals-A Guide for Pesticide Secondary Containment,” Ecology Publication #94-189. • “Site Evaluation-A Guide for Pesticide Secondary Containment,” Ecology Publication #94-188. • “Reducing and Managing Wastes From Catchbasins-A Guide for Pesticide Secondary Containment,” Ecology Publication #94-186. • “Spill Reporting and Cleanup in Washington State-A Guide for Pesticide Secondary Containment,” Ecology Publication #94-187. • “Pesticide Container Cleaning and Disposal,” Ecology Publication #96-431. • “Step By Step: Fact Sheets for Hazardous Waste Generators,” Ecology Publication #91-12. R.8 Air Quality Regulations Regulation of air pollutant emissions in Washington is controlled by seven local air pollution control agencies, three Ecology regional offices and two Ecology programs (Central Program’s Industrial Section, and Nuclear and Mixed Waste Program). All of the local air pollution agencies and the regional offices enforce local, state and federal air pollution regulations. The Industrial Section of Ecology’s Central Program enforces state and federal air pollution regulations at chemical pulp mills and aluminum reduction facilities. The Nuclear and Mixed Waste Program enforces state and federal air pollution regulation on the Hanford Nuclear Reservation. Whether it is to control the generation of fugitive emissions or point source (smoke stack) emissions, new and existing sources of air pollutants must comply with the requirements contained in their air pollution permits, regulatory orders, and local, state, and federal air pollution regulations. This will minimize the effects of each facility’s emissions on stormwater. Fugitive Particulate Matter Emissions: The local and state air pollution control agencies require that all reasonable precautions be taken to prevent fugitive particulate matter (windblown dust) from becoming airborne when handling, loading, transporting, and storing particulate material. Particulate materials of concern can include grain and grain dust, saw dust, coal, gravel and crushed rock, cement, and boiler fly ash. Some of the local authorities take the general requirement to control fugitive emissions further. For example, the Puget Sound and Benton County Air Pollution Control Agencies have defined what “reasonable precautions” means for various dust causing activities in their jurisdictions. Some actions that have been defined as “reasonable precautions” to prevent fugitive particulate emissions include paving of parking and storage areas, minimizing the area of land that has been cleared for housing development, various housekeeping activities such as sweeping paved areas, minimization of the accumulation of mud and dust and preventing mud and dust being tracked onto public roads, and stabilization of materials piles and open, cleared land areas with water sprays, chemical stabilizers or other means that minimize dust generation. All air authorities require sand blasting and spray painting activities be performed indoors with proper air pollution controls in use or, if that is not possible, out of doors but within acceptable, temporary enclosures. Gaseous Air Pollutant Emissions: Gaseous air pollutants are controlled at the point of origin through add-on emission controls or pollution prevention measures. Each emission point at a plant generally has emission limits that must be complied with. 89 Sources of gaseous air pollutants can include petroleum storage tank breather and pressure release systems, combustion units (boilers and heaters), commercial printers, can manufacturers, steel mills, pulp and paper plants, auto body repair shops, etc. Examples of gaseous air pollutants that can be emitted include acetone, methylene chloride, styrene, nitrogen oxides, benzene, carbon monoxide, alcohol, organic sulfides and petroleum, and chlorinated solvents. Some gaseous pollutants can be washed out of the air during rainstorms and enter stormwater. Others are photochemically degraded or converted in the air to other compounds that can be removed by rainfall or by settling on the ground. Gaseous air pollutants such as sulfur dioxide react in the air to generate acidic particulate matter. These particulates are usually removed from the atmosphere by settling out or being washed out of the air. In the case of sulfur oxides, this removal usually occurs at some distance (tens to hundreds of miles) from the facility that emitted the pollutant. R.9 Ecology Waste Reduction Program The 1990 Hazardous Waste Reduction Act, Chapter 70.95C RCW, established a goal to reduce dangerous waste generation by 50 percent. The primary means for achieving this goal is through implementation of a pollution prevention-planning program, also established in the Act. Facilities that generate in excess of 2,640 pounds of dangerous waste per year, or who are required to report under the Toxic Release Inventory (TRI) of Title III of the Superfund Amendments and Reauthorization Act (SARA), are subject to this law. Some 650 facilities in Washington currently participate in this planning program. Pollution prevention planning is an activity that involves: • Inventorying substances used and dangerous waste generated; • Identifying opportunities to prevent pollution; • Analyzing the feasibility of these prevention opportunities; and • Setting goals for hazardous substance use reduction and dangerous waste reduction, recycling and treatment. Ecology promotes pollution prevention through initiatives other than planning. Several campaigns targeting specific industries have been conducted and more are being planned. These campaigns have a joint focus of pollution prevention and regulatory compliance, and help target future technical assistance. Ecology provides technical assistance through its regional offices, with emphasis on the reduction of hazardous substance use and dangerous waste generation. Site visits, phone consultations, and workshops are some of the ways assistance is provided to businesses and governmental entities. Pollution prevention has emerged as a key strategy for protecting the environment. Business, industry and government alike recognize the benefits of prevention rather than end of pipe controls. Many factors, including regulatory compliance, cost savings, worker safety and reduced liabilities help validate pollution prevention as an approach to be incorporated into all business practices. R.10 Washington State Ground Water Quality Standards In December 1990, the state of Washington adopted ground water quality standards to prevent ground water pollution and protect both current and future beneficial uses of the resource. Beneficial uses of ground water include drinking water, irrigation, and support of wildlife habitat. These standards apply to any activity, including point and non-point, which has a potential to contaminate ground water. The standards protect all ground water within the saturated zone throughout the State of Washington and do not distinguish ground water that is isolated, seasonal, or artificial from that which is extensive and 90 naturally occurring. The standards incorporate an existing part of state water quality law: the antidegradation policy, which is an integral part of both the ground and surface water quality standards. The standards consist of both numeric criteria and narrative standards designed to protect both current and future beneficial uses of ground water. The numeric criteria for primary, secondary, and radionuclide contaminants have been adopted from the Federal Safe Drinking Water Act of 1971. Numeric criteria for carcinogenic compounds are based upon human health criteria. These criteria represent the maximum allowable contaminant concentration in ground water within the aquifer. However, the antidegradation policy requires that ground water quality be protected to the greatest extent possible prior to contaminant concentrations reaching those specified within the numeric criteria. To address this requirement, narrative standards were developed which are based upon background water quality and use of treatment technologies and are site specific in nature. Under these standards, specific early warning and enforcement limits are set at a point of compliance which must be met by a facility or activity if enforcement action is to be avoided. All facilities or activities within the State of Washington must first attempt to meet these narrative standards. The determination of specific limits is outlined in Implementation Guidance for the Ground Water Quality Standards, Ecology publication #96-02 (Ecology, 1996). In addition to using background ground water quality as a basis for determining specific early warning and enforcement limits, Washington law requires that all activities with the potential to contaminate water implement practices known as AKART – short for “all known available and reasonable methods of prevention, control and treatment.” AKART must be used regardless of the quality of the receiving waters. As technology and preventive controls are refined to better protect water quality, AKART is also redefined. In individual cases where AKART fails to protect water quality, the activity must apply additional controls. State law requires the permitting of any industrial, commercial, or municipal operation, which discharges waste material into ground and/or surface waters. These permits, issued by Ecology, set limits and conditions for discharges. Underground injection activities, while exempt from the State Waste Discharge Program, Chapter 173-216 WAC, are required to meet the ground water quality standards and may be permitted under Chapter 173-218 WAC, Underground Injection Control Program. Guidance for permit development will describe how an industry or commercial or municipal operation must conduct its activities in order to protect ground water quality. The ground water quality standards provide for several exemptions. One of these exceptions provides that the standards do not apply in the root zone of saturated soils where agricultural pesticides or nutrients have been applied at agronomic rates for agricultural purposes. The standards do apply below the crop's root zone. State approved BMPs may be considered one type of AKART for agriculture, and other point and non-point sources. Another exemption applies to any remedial or clean-up activity conducted under federal CERCLA or state Model Toxics Control Act. 91 Appendix IV-F: NPDES Stormwater Discharge Permits Summary: The Environmental Protection Agency’s (EPA) National Pollutant Discharge Elimination System Permit (NPDES) regulations for stormwater (40 CFR Parts 122, 123, and 124) became effective on November 16, 1990. Because Washington is an NPDES delegated state, it issues NPDES permits for designated industries, construction sites, and municipalities. Industrial Stormwater Permits: USEPA regulations list certain industrial activities (Reference: 40 CFR 122.26(b)(14) which may need to have a stormwater discharge permit. The following categories (1 through 10) of facilities are considered to be engaging in “industrial activity.” They are required by EPA to have a stormwater NPDES permit if they have a stormwater discharge to surface water. 1) Facilities subject to stormwater effluent limitations guidelines, new source performance standards, or toxic pollutant effluent standards under 40 CFR subchapter N (except facilities with toxic pollutant effluent standards under category 11 below). 2) Facilities classified by the Standard Industrial Classification (SIC) system as: 24 - Lumber and Wood Products except Furniture (except 2434- Wood Kitchen Cabinets) 26 - Paper and Allied Products (except 265-Paperboard Containers and Boxes, and except 267Converted Paper and Paperboard Products except Containers and Boxes) 28 - Chemicals and Allied Products (except 283-Drugs; and 285- Paints, Varnishes, Lacquers, Enamels, and Allied Products) 29 - Petroleum Refining and Related Industries 311- Leather Tanning and Finishing 32 - Stone, Clay, Glass and Concrete Products (except 323-Glass Products, made of Purchased Glass) 33 - Primary Metal Industries 3441 -Fabricated Structural Metal Products 373- Ship and Boat Building and Repair 3) Facilities classified by the Standard Industrial Classification (SIC) system as: 10 - Metal Mining 12 - Coal Mining 13 - Oil and Gas Extraction 14 - Mining and Quarrying of Nonmetallic Minerals, except Fuels (Includes active or inactive mining operations (except for areas of coal mining operations no longer meeting the definition of a reclamation area under 40 CFR 434.11(1) or except for areas of non-coal mining operations which have been released from applicable state or federal reclamation requirements by December 17, 1990) and oil and gas exploration, production, processing or treatment operations, or transmission facilities that discharge storm water that has come into contact with any overburden, raw material, intermediate products, finished products, byproducts or waste products located on the site of such operation. 92 4) Dangerous waste treatment, storage, or disposal facilities, including those that are operated under interim status or a permit under subtitle C of RCRA. 5) Landfills, land application sites and open dumps that receive or have received any industrial wastes (waste that is received from any of the facilities described under this subsection) including those that are subject to regulation under subtitle D of RCRA. 6) Facilities involved in the recycling of materials including metal scrap yards, battery reclaimers, salvage yards and automobile junkyards, including but not limited to those classified as SIC 5015-Wholesale Trade Activities of Motor Vehicle Parts, Used; and SIC 5093-Scrap and Waste Materials. 7) Steam electric power generating facilities, including coal-handling sites. 8) Transportation facilities classified under the following SIC codes, which have vehicle maintenance shops, equipment-cleaning operations, and airport deicing operations. 40 Railroad Transportation 41 Local and Suburban Transit and Interurban Highway Passenger Transportation 42 Motor Freight Transportation and Warehousing (except 4221- Farm Product Warehousing and Storage, 4222-Refrigerated Warehousing and Storage, and 4225General Warehousing and Storage) 43 United States Postal Service 44 Water Transportation 45 Transportation by Air 5171 Petroleum Bulk Stations and Terminals 9) Treatment works treating domestic sewage or any other sewage sludge or wastewater treatment device or system, used in the storage treatment, recycling, and reclamation of municipal or domestic sewage, including land dedicated to the disposal of sewage sludge that are located within the confines of the facility, with a design flow of 1.0 MGD or more, or required to have an approved pretreatment program under 40 CFR part 403. Not included are farmlands, domestic gardens or lands used for sludge management where sludge is beneficially reused and which are not physically located in the confines of the facility, or areas that are in compliance with section 405 of the Clean Water Act. 10) Construction activity including clearing, grading and excavation activities except: operations that result in the disturbance of less than one acre of total land area which are not part of a larger common plan of development or sale. (See “Construction Stormwater Permits” below) 11) Facilities under the following SIC classifications need to apply for a stormwater NPDES permit only if they are engaged in an “industrial activity” which is exposed to stormwater and they have a point source stormwater discharge to surface water. 20 Food and Kindred Products 21 Tobacco Products 22 Textile Mill Products 23 Apparel and Other Finished Products made from Fabrics and Similar Materials Wood Kitchen Cabinets 25 Furniture and Fixtures 265 Paperboard Containers and Boxes 93 267 Converted Paper and Paperboard Products, Except Containers and Boxes 27 Printing, Publishing and Allied Industries 283 Drugs 285 Paints, Varnishes, Lacquers, Enamels, and Allied Products 30 Rubber and Miscellaneous Plastic Products 31 Leather and Leather Products (except 311, Leather Tanning and Finishing) 323 Glass Products made of Purchased Glass 34 Fabricated Metal Products, Except Machinery and Transportation Equipment (except 3441, Fabricated Structural Metal Products) 35 Industrial and Commercial Machinery and Computer Equipment 36 Electronic and Other Electrical Equipment and Components, Except Computer Equipment 37 Transportation Equipment (except 373, Ship and Boat Building and Repair) 38 Measuring, Analyzing, and Controlling Instruments, Photographic, Medical and Optical Goods, Watches and Clocks 39 Miscellaneous Manufacturing Industries 4221 Farm Product Warehousing and Storage 4222 Refrigerated Warehousing and Storage 4225 General Warehousing and Storage For the industries identified in SIC categories (1) through (10), a permit is necessary if there is a point source stormwater discharge to a surface water, storm drain which discharges to surface water directly or indirectly, or a municipal storm sewer from any of the following areas of industrial activity: industrial plant yards; immediate access roads and rail lines used or traveled by carriers of raw materials, manufactured products, waste material, or by-products used or created by the facility; material handling sites; refuse sites; sites used for the application or disposal of process waste waters (as defined at 40 CFR part 401); sites used for the storage and maintenance of material handling equipment; sites used for residual treatment, storage, or disposal; shipping and receiving areas; manufacturing buildings; storage areas (including tank farms) for raw materials, and intermediate and finished products; and areas where industrial activity has taken place in the past and significant materials remain and are exposed to storm water. Industries in Categories 1 through 9 can submit an application and qualify for a Conditional “No Exposure” Certificate. For the industries identified in SIC category (11), a permit is required for point source discharges from any of the areas that are listed above (except access roads and rail lines of SIC category 11 industries), only if material handling equipment or activities, raw materials, intermediate products, final products, waste materials, by-products, or industrial machinery are exposed to stormwater. However, they must submit a “No Exposure” Certificate to be excused from the permit. How and When Do I Apply for A Permit? Three types of permits are possible. Each has a different application process. General Permit for Industrial Activities: An application for coverage under the Industrial Stormwater General Permit, referred to as a Notice of Intent (NOI), must be submitted to Ecology. 94 Individual Permit: An industrial facility that is required to have a stormwater permit may volunteer or be required to apply for an individual permit. An individual permit is a permit that is written for and issued to a specific facility. EPA regulations require that industries not covered under a general permit must apply for an individual stormwater permit. Individual permit applicants for discharges composed entirely of stormwater, must comply with 40 CFR 122.21, and complete EPA forms 1 and 2F. Ecology is prepared to issue individual permits for facilities not already under permit only for exceptional circumstances. Industry-Specific General Permits: Ecology will consider development of industry-specific general permits, as needed. An industry-specific permit is a permit that can apply to all industries of a similar type. Examples of industry-specific general permits that include stormwater are Sand and Gravel, and Boatyards. What Does The Industrial Stormwater General Permit Require Industries To Do? The development of an Industrial Stormwater Pollution Prevention Plan (SWPPP) by each industry is a key Permit requirement. The Industrial SWPPP requirements include: • Identifying the potential sources of pollutants that may contaminate stormwater. • A description and implementation of operational and structural source control BMPs to reduce the stormwater pollutants and comply with the stormwater general permit. The permit also includes requirements for: • Effluent limitations for certain types of industrial facilities, and certain discharges to 303(d) impaired waterbodies; • Monitoring: All facilities are required to conduct quarterly monitoring and sampling. There are additional monitoring requirements for certain, identified industry groups; • Application of additional source control and treatment BMPs to control pollutants further if certain “benchmark” levels of pollutants, as identified in the permit, are exceeded; • Reporting and Recordkeeping; • Operation and Maintenance Municipalities May Have To Apply for an Industrial Stormwater Permit or Other General Permit Some municipalities own or operate an “industrial activity.” If that industrial activity has a stormwater discharge to surface waters or storm drains tributary to surface waters, the municipality must apply for the Industrial Stormwater General Permit (or applicable industry-specific general permit, e.g., Sand & Gravel General Permit, Boatyard General Permit, etc.) unless the site qualifies for a Conditional “No Exposure” Certificate. In the latter case, a “no exposure” application form should be submitted. Examples of industrial activities conducted by municipalities include, but may not be limited to: sand and gravel mining; crushed and broken stone operations; rip rap mining and quarrying; landfills, recycling facilities, land application sites, and open dumps that receive or have received industrial waste; transportation facilities which have vehicle maintenance shops; equipment cleaning; airport de-icing operations; and sewage treatment plants with a design flow above one million gallons per day; and power plants. Construction Stormwater Permits Construction sites that will disturb one acre or more and will have a discharge of stormwater from the project site to surface water must apply for Ecology's Construction Stormwater General Permit. The permit requires application of stabilization and structural practices to reduce the potential for erosion and the discharge of sediments from the site. The stabilization and structural practices cited in the 95 permit are similar to the core requirements for sedimentation and erosion control in Volume I and II of the SWMM; refer to the Construction Stormwater General Permit for specific requirements. Municipal Stormwater Permits NPDES Permit Program for Municipal Stormwater Discharges Phase I. Ecology has issued stormwater discharge general permits to the cities of Seattle and Tacoma; the counties of King, Pierce, Clark, and Snohomish; and the discharges from state highways managed by the Department of Transportation within those jurisdictions. These permits contain conditions for compliance with both federal and state requirements and are issued as combined NPDES and State Wastewater Discharge Permits. Ecology reissued the Phase I general permit in 2007 and plans to reissue the next permit in 2012. Phase II. The EPA adopted Phase II stormwater regulations in December 1999. Those rules identify additional municipalities as subject to NPDES municipal stormwater permitting requirements. Over 100 municipalities in Washington are subject to the requirements. Federal regulations required issuance of Phase II permits by December 2002, and required the Phase II communities to submit their stormwater programs to comply with permit requirements by March 2003. Ecology issued the Phase II permits for Eastern Washington and Western Washington in 2007 and plans to reissue these two general permits in 2012. 96 Appendix IV-G: Example of an Integrated Pest Management Program Integrated Pest Management (IPM) is a natural, long-term, ecologically based systems approach to controlling pest populations. This system uses techniques either to reduce pest populations or maintain them at levels below those causing economic injury, or to so manipulate the populations that they are prevented from causing injury. The goals of IPM are to encourage optimal selective pesticide use (away from prophylactic, broad spectrum use), and to maximize natural controls to minimize the environmental side effects. A step-by-step comprehensive Integrated Pest Management (IPM) Program is provided below as a guide: Introduction This section provides a sound cultural approach to managing lawns and landscapes and minimizing runoff. Many homeowners or property managers will be able to implement most or all of this approach, others will wish to hire these services out. For the do-it yourselfer, an array of resources are available to assist in the effort. Landscaping businesses, agricultural extensions, local agencies, master gardener programs, local nurseries and even the library can all provide assistance. Landscaping professionals (businesses) are particularly encouraged to practice IPM. Definition “Integrated pest management, or IPM, is an approach to pest control that uses regular monitoring to determine if and when treatments are needed, and employs physical, mechanical, cultural, and biological tactics to keep pest numbers low enough to prevent intolerable damage or annoyance. Leasttoxic chemical controls are used as a last resort.” True IPM is a powerful approach that anticipates and prevents most problems through proper cultural practices and careful observation. Knowledge of the life cycles of the host plants and both beneficial and pest organisms is also important. The IPM section of this study guide is adapted from Least Toxic Pest Management for Lawns by Sheila Daar, Following the IPM process gives you the information you need to minimize damage by weeds, diseases and pests and to treat those problems with the least toxic approaches. The Integrated Pest Management Process Step One: Correctly identify problem pests and understand their life cycle. Learn more about the pest. Observe it and pay attention to any damage that may be occurring. Learn about the life cycle. Many pests are only a problem during certain seasons, or can only be treated effectively in certain phases of the life cycle. Step Two: Establish tolerance thresholds for pests. Every landscape has a population of some pest insects, weeds, and diseases. This is good because it supports a population of beneficial species that keep pest numbers in check. Beneficial organisms may compete with, eat, or parasitize disease or pest organisms. Decide on the level of infestation that must be exceeded before treatment needs to be considered. Pest populations under this threshold should be monitored but don’t need treatment. For instance, European crane flies usually don’t do serious damage to a lawn unless there are between 25 – 40 larvae per square foot feeding on the turf in February (in normal weather years). Also, most people consider a lawn healthy and well maintained even with up to 20% weed cover, so treatment, other than continuing good maintenance practices, is generally unnecessary. 97 Step Three: Monitor to detect and prevent pest problems. Regular monitoring is a key practice to anticipate and prevent major pest outbreaks. It begins with a visual evaluation of the lawn or landscape's condition. Take a few minutes before mowing to walk around and look for problems. Keep a notebook, record when and where a problem occurs, then monitor for it at about the same time in future years. Specific monitoring techniques can be used in the appropriate season for some potential problem pests, such as European crane fly. Step Four: Modify the maintenance program to promote healthy plants and discourage pests. A healthy landscape is resistant to most pest problems. Lawn aeration and overseeding along with proper mowing height, fertilization, and irrigation will help the grass out-compete weeds. Correcting drainage problems and letting soil dry out between waterings in the summer may reduce the number of crane-fly larvae that survive. Step Five: If pests exceed the tolerance thresholds Use cultural, physical, mechanical or biological controls first. If those prove insufficient, use the chemical controls described below that have the least non-target impact. When a pest outbreak strikes (or monitoring shows one is imminent), implement IPM then consider control options that are the least toxic, or have the least non-target impact. Here are two examples of an IPM approach: 1. Red thread disease is most likely under low nitrogen fertility conditions and most severe during slow growth conditions. Mow and bag the clippings to remove diseased blades. Fertilize lightly to help the grass recover, then begin grasscycling and change to fall fertilization with a slow-release or natural-organic fertilizer to provide an even supply of nutrients. Chemical fungicides are not recommended because red thread cannot kill the lawn. 2. Crane fly damage is most prevalent on lawns that stay wet in the winter and are irrigated in the summer. Correct the winter drainage and/or allow the soil to dry between irrigation cycles; larvae are susceptible to drying out so these changes can reduce their numbers. It may also be possible to reduce crane fly larvae numbers by using a power de-thatcher on a cool, cloudy day when feeding is occurring close to the surface. Studies are being conducted using beneficial nematodes that parasitize the crane fly larvae; this type of treatment may eventually be a reasonable alternative. Only after trying suitable non-chemical control methods, or determining that the pest outbreak is causing too much serious damage, should chemical controls be considered. Study to determine what products are available and choose a product that is the least toxic and has the least nontarget impact. Refer to the Operational BMPs for the use of Pesticides below for guidelines on choosing, storing and using lawn and garden chemicals. Step Six: Evaluate and record the effectiveness of the control, and modify maintenance practices to support lawn or landscape recovery and prevent recurrence. Keep records! Note when, where, and what symptoms occurred, or when monitoring revealed a potential pest problem. Note what controls were applied and when, and the effectiveness of the control. Monitor next year for the same problems. Review your landscape maintenance and cultural practices to see if they can be modified to prevent or reduce the problem. A comprehensive IPM Program should also include the proper use of pesticides as a last resort, and vegetation/fertilizer management to eliminate or minimize the contamination of stormwater. 98 06 Habitat for Humanity Yelm - Final Plat Map.pdfSV-1 R E G I S T E R E D S T A T E O F W A S H I N G T O N P R O F E S S I O N A L L A N D S U R V E Y O R R E G I S T E R E D S T A T E O F W A S H I N G T O N P R O F E S S I O N A L L A N D S U R V E Y O R 07 Habitat for Humanity Yelm - DRAFT STEP Sewer System Easement - Corporate.pdfUTILITY EASEMENT Page 1 of 2 STEP SEWER SYSTEM EASEMENT (CORPORATE FORM) THIS INDENTURE, made this _____ day of __________, 20____, between South Puget Sound Habitat for Humanity, hereinafter called the GRANTOR, and the CITY OF YELM, a Municipal Corporation, hereinafter called the GRANTEE, WITNESSETH: For good and valuable consideration, receipt of which is hereby acknowledged, the Grantor hereby grants and conveys to the Grantee, its successors and assigns, A PERPETUAL EASEMENT FOR operation, maintenance and repair of septic tanks, pump chambers, pressure sewer connection lines and pump electrical services, over, under, upon and through a portion of that certain real property situate and being in the County of Thurston, State of Washington, more particularly described as follows, TO WIT: PERMANENT EASEMENT: PARCEL: (PER STATUTARY WARRANTY DEED AF #4742143) BOUNDRY LINE ADJUSTMENT NO.

Box 2225 Olympia, WA 98507 Attn: Ben Fransua, Director of Construction Re: Verification Testing Services Yelm Planned Residential Development Yelm, Washington Sage Project No. 052002 Dear Mr. Fransua: At the request of South Puget Sound Habitat for Humanity (SPS Habitat, project owner), Sage Geotechnical, LLC (Sage) completed verification testing in support of the Yelm Planned Residential Development project. The results of the verification testing are summarized herein. PROJECT UNDERSTANDING SPS Habitat is developing a 2.3-acre parcel located at 407 Longmire Street Northwest in Yelm, Washington (site). The City of Yelm has required verification testing of two existing stormwater infiltration ponds. The approximate locations of the ponds are shown on Attachment 1. VERIFICATION TESTING The stormwater pond in the western half of the site has a 300-square-foot (sf) base and 3 horizontal to 1 vertical side slopes partially vegetated with grass. The stormwater pond in the eastern half of the site has a 200-sf base with gentle slopes covered in mulch. On February 27, 2025, Sage completed verification tests of the two stormwater ponds. Testing was completed in accordance with the U.S. Environmental Protection Agency’s (EPA) falling head percolation test procedure. The test procedure and locations were selected by LDC, Inc. (project civil engineer). The verification tests included multiple trials; during each trial, 6 inches of water was infiltrated into the base of the pond. The trials were repeated until they yielded similar infiltration rates. Yelm Planned Residential Development March 4, 2025 2 SageGeotechnical.com March 4, 2025 Infiltration rates were calculated in accordance with the EPA’s falling head percolation test procedure. This procedure does not include correction factors or factors of safety. Sage calculated a field infiltration rate of 15.8 inches per hour for the western pond and 9.6 inches per hour for the eastern pond.
