Let us know if there are any components that are missing from these pages. Ignore the requirements that do not apply to your system. You should plan to complete a checklist for all system components on the following schedule: (1) Monthly from November through April. (2) Once in late summer(preferably September). (3) After any major storm (use 1 - inch in 24 hours as a guideline), items marked "S" only. Using photocopies of these pages, check off the problems you looked for each time you did an inspection. Add comments on problems found and actions taken. Keep these "checked" sheets in your files, as they will be used to write your annual report (due in May). Some items do not need to be looked at every time an inspection is done. Use the suggested frequency at the left of each item as a guideline for your inspection. You may call the jurisdiction for technical assistance. Please do not hesitate to call, especially if you are unsure whether a situation you have discovered may be a problem.

Comments: ATTACHMENT B POLUTION SOURCE CONTROL PROGRAM Purpose Many products and practices commonly used in and around the home are hazardous to both the environment and us. Many of these products can end up in our stormwater systems and groundwater. This document gives alternatives, where possible, for those types of products and practices. The Best Management Practices (BMPs) described here include "good housekeeping" practices that everyone can use. Pollution Control Practices Of particular concern are drives and parking areas. Because of heavy vehicle usage, the concentration of oil and grease in stormwater may exceed the Ecology guidelines of 10 mg/I. Although there are no local data to confirm this view, limited research in the San Francisco Bay area found the mean concentration of oil and grease in stormwater to exceed 10 mg/I. The following actions shall be taken to ensure that pollution generated onsite shall be minimized: • Sediment removed from basins, ponds, and swales shall be disposed of in a proper manner. Contact the local governing jurisdiction for inspection prior to completing this task. • No activities shall be conducted onsite that are likely to result in short-term, highly concentrated discharge of pollution to the stormwater system. Such activities may include, but are not limited to, heavy vehicle maintenance, and cleaning of equipment used in the periodic maintenance of buildings and paved surfaces. Ideas will help you reduce the risks of stormwater and groundwater contamination from many household products. 1. Read product labels before purchasing. Toxic product labels will carry many warnings. Either bypass such products or purchase in small quantities. If you cannot use the entire product, try to give it away instead of disposing of it. Thurston County periodically facilitates product exchanges for leftover paints and other hazardous wastes. Call the Thurston County Health Department at (360) 754-41 11 for more information. 2. Buy only those detergents that contain little or no phosphorus. Phosphorus can cause algae blooms if washed into lakes or streams. Most detergents that are low in phosphates or phosphate free are labeled as such. 3. Use no more than the manufacturer's suggested amount of any cleanser. More is not necessarily better. 4. Products such as oven cleanser, floor wax, furniture polish, drain cleaners and spot removers often contain toxic chemicals. Buy the least toxic product available or use a non- toxic substitute if one can be found. For example, ovens can be cleaned by applying table salt to spills then scrubbing with a solution of baking soda and water. Table 2 lists substitutes for many commonly used household products. If it is necessary to use a product that contains toxic chemicals, use the product only as directed. Do not combine products, as they may become more dangerous when mixed (e.g., mixing chlorine bleach and ammonia produces dangerous gases). Use eye protection and rubber gloves as appropriate. Contact the Hazardous Substance Hotline at 1-800-633-7585 if you have any questions regarding disposal of a product or empty container. The County has both hazardous waste collection days and permanent facilities where residents can bring hazardous wastes. Call the Thurston County Health Department at (360) 754-4111 for more information. 5. Chemicals left over from activities, such as photography and auto repair, are hazardous and should not be flushed down the sink. This is especially important if your home or business is hooked up to a septic system. Toxic chemicals can kill the beneficial bacteria in the tank used to treat sewage and can pollute water supply wells. 6. Be sure all containers are clearly labeled. 7. Common batteries (not automobile) are one of the largest sources of heavy metals (such as lead, nickel, cadmium and mercury)found in landfills. Instead of throwing them away, dispose of them at a hazardous waste collection site. AUTOMOTIVE USAGE,CARE AND MAINTENANCE From a waste management standpoint, automobile maintenance is best done by professionals at facilities designed to handle, store and dispose of the waste products properly. Many of these facilities do an excellent job of dealing with waste oils, antifreezes, other fluids, batteries and tires. They often charge a small fee to cover the added expenses, but iYs worth it. However, if you repair your car at home, please consider these helpful tips: Pesticides and Fertilizers Pesticides and fertilizers are commonly used in a quest for bigger, healthier plants and greener, lusher lawns. These chemicals are often overused and misapplied. These chemicals are easily introduced into stormwater runoff and can cause algae blooms (fertilizers) or kill off aquatic organisms (pesticides). FERTILIZER MANAGEMENT Fertilizing a lawn can be done in an environmentally sensitive manner. Here are some ideas. 1. Before fertilizing, test your soil's pH by using a readily available kit or through tests provided by WSU Cooperative Extension. Use only the recommended amount of fertilizer and any soil amendments, such as lime, that are recommended in your test results. 2. Use fertilizers that are appropriate for your area and for the types of plants you are growing. Work the fertilizer into the soil directly around the plant's drip line. By incorporating the fertilizer in the soil, there will be less likelihood of contaminated runoff. Contact the Thurston Conservation District for more information. 3. Water before fertilizing. Water enough to dampen the ground thoroughly but not enough to cause surface runoff. Dampening the soil prevents fertilizer from being washed from the surface of dry soil in the first rain or watering after application. 4. Many soils can benefit from the use of organic fertilizers such as compost or peat. Not only do these substances add nutrients to soil; they also increase the porosity of the soil and increase its ability to hold water. 5. Slow release fertilizers (which are generally resincoated) can be used in addition to organic fertilizers. They are not mobile in the soil and are applied only once. INTEGRATED PEST MANAGEMENT Rather than bringing out the sprayer whenever a pest infestation occurs in the garden, consider using Integrated Pest Management (also known as IPM). IPM emphasizes the evaluation of all factors including environmental effects before chemicals are applied. Pesticides should only be used as a last resort. Some of the tactics that can be used to decrease or eliminate the use of pesticides include: 1. Use of Natural Predators or Pathogens: Because chemical sprays generally kill many beneficial insects instead of just the target pest, it may be necessary to introduce natural predators back into the garden. Ladybugs, lacewings, predatory wasps and nematodes are all commercially available. Garter snakes and toads are also predators and should not be eliminated from the garden. There are some bacteria, viruses and insect parasites that are specific to pests and will not harm other insects or animals. A commonly used bacterium in the Puget Sound area is Bacillus thuringiensis (Bt), which is intended to control infestations of tent caterpillars. Products containing Bt are available at your nursery. As used here, the word pesticide can mean any herbicide, insecticide, rodenticide, miticide or other types of chemicals used in the same manner. Many pesticides bind to soil particles and can be easily carried into a stream or storm drain. 5. Pesticides should be stored well away from living areas. Ideally, the storage area should have a cement floor and be insulated from temperature extremes. Always keep pesticides in their original containers with labels in tact. Labels often corrode and become illegible in this climate and may have to be taped onto the container. 6. Federal law now requires that all pesticides be labeled with the appropriate disposal method. Leftovers should never be dumped anywhere, including a landfill. Take unwanted pesticides to the advertised collection site on the County's hazardous waste collection days or to Hazo House at the landfill. 7. Empty containers should be triple-rinsed and the rinse water used as spray. Once containers are triple-rinsed, they are not considered hazardous waste and may be disposed of in most landfills. However, call your local landfill before putting the container in the garbage. 8. If a pesticide is spilled onto pavement, it can be absorbed using kitty litter or sawdust. The contaminated absorbent should be bagged, labeled and taken to Hazo House. 9. If the pesticide is spilled onto dirt, dig up the dirt, place it in a plastic bag and take it to Hazo House. . 10. Many pest control companies and licensed applicators have access to pesticides that are more toxic than those available to the consumer. Check with the company before they spray indoors or outdoors to find out what spray they will be using and what precautions, if any, are necessary after the operator leaves. Remodeling Remodeling uses some of the most toxic substances found in the home. Paints, preservatives, strippers, brush cleaners and solvents all contain a wide range of chemicals, some of which are suspected to be carcinogenic (cancer causing). These products should never be dumped in a landfill or put down a sewer or septic system. 1. When building a deck cQnsider using wood or wood alternatives such as recycled woodlplastic decking instead of concrete. Wood decking allows rainwater to drip onto the ground below, keeping it from becoming surface runoff 2. Decks and sidewalks can also be built out of brick interlocking pavers or modular concrete. If these surfaces are placed on a bed of welldrained soil gravel or sand, rainwater can infiltrate into the ground around them. 3. To reduce disposal problems, buy only the needed amount. Used turpentine or brush cleaner can be filtered and reused. Paint cans should be allowed to dry and then be disposed of during a hazardous waste collection day or at Hazo House. 4. Leftover paint can be given away, for example to a theater group. Contact the Thurston County Health Department at (360) 754-4111 for other options.
