The purpose of this chapter is to give alternatives, where possible, for those types of products end practices. There are two categories of BMPS in this chapter. The first category of BMPS includes "good housekeeping" practices that everyone should use. The second category of BMPS deals with erosion and pollution control practices for people who raise large animals. RECOMMENDED POLLUTION CONTROL PRACTICES FOR HOMEOWNERS It has been said that theaverege home today contains more chemicals than the average chemical lab of .100 years ago. When many of these chemicals are used industrially, they can be subject to various health and safety standards; yet these same substances are used freely and often carelessly in homes across the nation. The BMPS in this section are divided into four categories: Household Hazardous Wastes, Pesticides, Remodeling, and Septic Maintenance. Each section includes information on available alternatives. Household hazardous wastes Many of the cleaning agents, solvents, polishes, etc. used commonly in the home are considered hazardous wastes. These products may be toxic, corrosive, reactive, flammable, and/or carcinogenic. It is critical that these products are disposed of properly. A list of some common household hazardous wastes is presented in Table 1. In addition, many hazardous household chemicals persist for long periods of time in the environment. Manufacturers may truthfully state that a product is "biodegradable"; most products are biodegradable, but what is important is the ~ at which they are broken down and the products they are broken down into. The term "biodegradable" on its own is thus rather meaningless unless the product is rapidly degraded into harmless breakdown products.

This means that any product can use this term according to the manufacturer's own definition. This definition may not be at all similar to the consumer's perception. Household product management Buy only those detergents that contain little or no phosphoru. Phosphorus can cause algae blooms if it is washed into lakes, streams, bays or from septic systems into ground water. Most detergents wfiich are low or phosphate free are labeled as such. 2. Use only the manufacturer's suggested amount of any cleaner. More is not necessarily better. 3. Products such as oven cleaner, floor wax, furniture polish, drain cleaners, and spot removers often contain chemicals that are toxic. Buy the least toxic product available, and use anon-toxic substitute if one can be found. Ovens, for example can be cleaned by applying table salt to spills, then scrubbing with a solution of washing soda and water. Table 2 lists some substitutes for commonly used household cleaners. If it is necessary to use a product that contains toxic chemicals, then use the product only as directed. Do not combine Droducts, as they may become more dangerous when mixed (such as chlorine bleach and ammonia). Use protective clothing and rubber gloves. Contact the HezaMous Substance Hotline at 1-800-633-7585 if you have any Questions regarding how to dispose of a product or empty container. Many areas now have either hazardous waste collection days, or permanent facilities where residents can bring hazardous wastes. Call your county's environmental health department for further information. 4. Chemicals left over from such hobbies as photography are hazardous and should not be flushed down the sink. This is especially important if your home is hooked up to a septic system. Toxic chemicals can kill the bacteria in the tank that treat sewage.

Buy toxic products in small quantities. If you cannot use all of the product, try to give it away instead of disposing of it. 6. Be sure that the contents of all containers are clearly marked. 7. Common (not automobile) batteries are one of the worst sources of heavy metals found in landfills: Instead of throwing them away, dispose of them at a hazardous waste collection site. AUTOMOTIVE USAGE, CARE AND MAINTENANCE t. Cars should be serviced regularly. Any leaky lines or valves should be replaced. Dumping oil, degreasers, antifreeze, and other automotive liquids into a stream or a storm drain is illeoal. Do not dump them onto the ground because they will end up in stormwater runoff once it rains. Do not use oil to reduce dust levels on unpaved areas. 2. If possible, recycle used oil and antifreeze. Keep them in separate containers. Call the Recycling Hotline at 1-800-RECYCLE for the location of the nearest recycling center or call your local gas stations. 3. Wrap empty oil or antifreeze containers in several layers of newspaper, tie securely and place in a covered trash can. Antifreeze is sweet-tasting, but poisonous to people, fish, pets and wildlife. 4. Sweep your driveway instead of/or before hosing it down. Many toxicants and heavy metals associated with automobiles can build up on driveway surfaces and be washed into local surface water when driveways are hosed down. 5. When washing vehicles, direct soapsuds onto the lawn or another vegetated area to keep the soap from washing into the local surface water. 6. Small spills of oil and other fluids can be absorbed by using materials such as kitty litter or sawdust. Wrap the used kitty litter and any contaminated soil in a plastic hag and then place it in the garbage. If a spill reaches surface water, you must notify the nearest regional office of the Department of Ecology: Residential Best Management Practices 3974467 Page 22 of 35 TM1UZSt ooWCO~n IYZWasftin9too g~eement CITY OF YE~M (IIIIIII III IIIIII VIII IIII IIIIII VIII IIII IIIIIII IIIIII IIII IIII VIII VIII IIIIIII III VIII VIII IIII IIII Stormwater Program Guidance Manual Volume /l Northwest Region -Redmond 867-7000 (24hour) Southwest Region -Olympia 753-2353 (24-hour) There era fines for failure to notify the appropriate agency when a spill occurs Deicing chemicals (most commonly salt) are often used on private sidewalks and driveways during cold winter weather. These chemicals can harm concrete less than three years in age, and burn vegetation. They are also corrosive to cars and other metal objects. Not only are the deicing chemicals pollutants, but the additives are often pollutants as well. Cyanide is formed from the breakdown of a common ami-caking agent used in deicing chemicals. - Urea salts have been proposed as an alternative to other types of salt deicers, but great care must he used in applying them: These salts contain large quantities of nitrogen, which can severely burn plants if over-applied. The use of these chemicals should be minimized or avoided if possible. While deicing chemicals are more effective in removing snow from roads than are grits such as sand, they cause much worse pollution and if used at all should be used in moderation. SMALL BOAT USAGE, CARE AND MAINTENANCE In narrow creeks and coves boat wakes can contribute to shoreline erosion. To minimize erosion, boats should not produce wakes within 500 feet of shore. A speed greater than 8 knots can cause a wake with great erosive force. 2. When washing a boat, use low phosphate or phosphate free detergent. Using a brush and scrubbing the boat down after each use can minimize the need for washing. When possible, avoid stain-removing products as they are generallytoxic.

Boat hulls may have been repainted with tributyltin (a paint) to prevent fouling. This type of paint is eMremely toxic to marine life. When scraping the boat bottom, catch tha scrapings with a drop cloth. Compress the scrapings into as small a can as possible, label the can and turn it in to the nearest household hazardous waste collection center. Repaint the hull using acopper-based paint. Copper-based paints are less toxic )although not non-toxic) to marine life. PESTICIDESt AND FERTILIZERS Pesticides (such as insecticides and herbicides) and fertilizers are commonly used by homeowners in their quest for bigger, healthier plants. These chemicals are easily overused. Homeowners often do not know just how much fertilizer is necessary in their soil. Often, people assume that more is better. These chemicals are easily introduced into stormwater runoff and can cause algae blooms (fertilizers) or kill off aquatic organisms (pesticides). Fertilizer manacement 1. Before fertilizing, test your soil. This can be easily done by using kits that are available, or through tests provided by the County Cooperative Extension office in your area. Use only the recommended amount of fertilizer. 2. Use fertilizers that are appropriate for your area, and for the type of plants you are growing. Work the fertilizer into the soil directly around the plant's drip line. By incorporating the fertilizer into the soil, there will be less likelihood of contaminated runoff. 3. Water before fertilizing. Water enough to dampen the ground thoroughly, but not enough to cause surface runoff. ~. 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. ' As used here, the word pesticide can mean arty herhicide, insecticide, rodenticide, miticide or other types of chemicals used in the same manner.

Slow release fertilizers Iwhich are generally resin-coated) can be used in addition to organic fertilizers. They are not mobile in the soil, and are only applied once, which saves work. Integrated oast management Rather than bringing out the sprayer whenever a pest infestation occurs in the garden, consider using Integrated Pest Management (also known as IPM1. IPM emphasizes the evaluation of all factors including environmental effects before chemicals are applied. Pesticides should only be used as a last resort. IPM maximizes the use of natural pest controls. Soma of the tactics that can be used to decrease or eliminate the use of pesticide sprays include: 11se of Natural Predators Pathogens: Because 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 8aci//us thuringiensis (Bt), which is intended to control infestations of tent caterpillars. Habitat Changes: Many times a change of habitat can control pest infestations. Removal of old tires can cut down on the mosquito population by removing a convenient water-filled location that they can breed in. Crop rotation, even in a small garden can reduce the number of pest infestations. Removing last year's leaves from under rose bushes can cut down on the ineidenca of mildew and blackspot, as these fungi overwinter in dead leaves. Timin Crops that can overwinter (such as leaks or carrots) should be planted in the fall. This gives them the time to become established before pests appear in the spring. Mechanical: Many eggs, larvae, cocoons, and adult insects can be removed by hand. Be sure that the insect is properly identified prior to removing it so that Residential ~ p Best Management Practices 3974467 Page 29 of 35 11 R9/l00] 0010 GM P9feemenl TM1W Ston County WaiF ingl on CITY OF YELM IIIIIII III IIIIII VIII IIII IIIIII VIII IIII IIIIIII IIIIII IIII IIII VIII VIII IIIIIII III VIII VIII IIII IIII Stormwater Program Guidance Manual Volume 11 beneficial insects are not destroyed in error. Drowning insects in water is an alternative to squashing them. Resistant Plants: Plants that are native to this area are often more resistant to pests and climate, etc. than are introduced plants. Many plant cultivars have been developed which are resistant to such diseases as verticilium wilt and peach leaf curl. Growino Conditions: Plants, such as hostas, that require some shade are more susceptible to pests when they are grown in sun. Plants that are not properly fertilized or watered are less vigorous in growth and tend to attract pests. Plants that prefer an acid soil, such as azaleas, will perform better and be less susceptible to pests when they are grown in soil with the proper pH. h ical : Chemicals are a small Dart of the entire IPM plan and should be applied only as needed after reviewing all other alternatives. Pesticide manaaement Know what pest you are spraying tor. Use the pesticide according to the manufacturer's instructions and buy only the quantity needed. Many pesticides have a limited shelf life and may be useless or degrade into even more toxic compounds if kept on the shelf. 2. Do not apply more than the specified amount. Overuse can be dangerous to your health as well as the health of wildlife and the environment. ff more than one chemicalcan be used to control the pest, choose the least toxic. The word "caution" on the label means that the chemical is less toxic than one that is labelled "warning." 3. Do not spray on windy days, in the morning of what will be a very hot day, or when rain is likely to occur. Herbicides can drift and injure valuable ornamentalplants in either your or your neighbor's back yard. Do not water heavily after application. Plants should be lightly watered BEFORE application to prevent burning of the foliage.

Never ePPIY Pesticides near streams, ponds, or wetlands. Do not apply them to bare or eroded ground. 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 intact. 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 labelled with the appropriate disposal method. Leftovers should never be dumped anywhere, including a landfill. Many counties in this area conduct hazardous waste collection days or collect waste regularly at the landfill. Contact the county environmental health department for more information. 7. Empty containers should be triple-rinsed and the leftover rinse water used as spray. Once containers are triple-rinsed, they are not considered hazardous waste end 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 he absorbed using kitty litter or sawdust. The contaminated absorbent should be bagged and labeled and taken to a hazardous waste collection site. If the pesticide is spilled onto dirt, dig up the dirt, place it in a plastic bag and take it to a hazardous waste collection center. 9. 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. HOME 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 carcinogens (cancer-causing). These products should never be dumped in a landfill or put down a sewer or septic system.

Vc/ume // 1. When building a deck consider using wood instead of concrete. Wood decking allows rainwater todrip 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 well-drained soil, gravel or sand, rainwater can infiltrate into the ground through them. 3. To reduce disposal problems, buy only the amount you need. Used turpentine or brush cleaner can be filtered and reused. Paint cans should be allowed to dry and then ba disposed of during a hazardous waste collection day or at a permanent collection location. 4. Large amounts of.leftover paint canbe given away, for example to a theater group. Currently, the City of Seattle is experimenting with recycling latex paint turned in as hazardouswaste. It is blended, cleaned, tinted, and is now being sold on a trial basis as "Seattle Beige." 5. Roof downspouts can be adapted to infiltrate runoff where the soil is well drained. The runoff from them can enter a gravel bed where it can infiltrate into the ground. For design criteria, see BMP RI.15, Roof Downspout Systems in Volume III of the stormwater Management Manual for the Puget Sound Basin. 6. When gardening on slopes, reduce the potential for surface runoff by using terraces across the face of the hill. These can be as simple as little soil "bumps" or can be elaborate using such products as pressure-treated woad 4x4s or rock walls. SEPTIC SYSTEM CARE AND MANAGEMENT While septicsystems do not seem to have a direct relationship with stormwater runoff, they can in some instances be related. Roof drains and stormwater runoff should be diverted away from drainfields. Excess water reduces the capacity of the drainfield to absorb effluent from the septic tank.

Water from fiot tubs should not be drained into a septic system all at once. They are not designed to handle large volumes of chlorinated water. Either use the water on plants in the yard, or drain the hot tub slowly over'a period of days. 3. Septic tank tanks should be pumped regularly. Ponded water, damp places in the yard, foul odors and/or a dark gray or black soil color may indicate septic drainfield failure. Effluent from a malfunctioning septic tank can cause disease and nitrate problems in groundwater. LARGE ANIMAL MANAGEMENT People often own livestock in low-density residential areas. Horses are the most popular animal, but goats, cows, sheep, llamas, pigs and chickens are also kept. Nearby streams and lakes can be adversely affected by manure-contaminated stormwafer draining from pastures. Dvergrazing, a common problem, denudes pastures and allows excessive runoff and erosion. Contamination frequently occurs when animals defecate directly into a lake or stream. Streambanks can also be broken down. It is essential for livestock owners to install BMPS similar to those described below. Not only will they help in contrdling water quality, but they wilt help maintain productive pastures by increasing the grass cover and reducing erosion. Pasture management Pastures should be fenced to keep animals away from surface water. If stock must he watered at a stream, use cramp-and-fence system to keep them out of the water (Figure 11. A minimum 70-foot strip of vegetation should be left between the fence and the water. 2. If the buffer area around the water cannot be fenced, it should be planted with a "living fence," vegetation that is impenetrable to livestock. The buffer strip should be at feast 25 feet wide. Consult with local government for any other restrictions andlor the restrictions contained in a Sensitive Areas Ordinance, if passed. 3. Avoid overgrazing. Restrict grazing during the winter months when grasses are dormant and easily overgrazed. Grazing when the soil is wet can cause compaction Residential t q Best Managemenl Practices 3974467 Page 33 of 35 11 /29/2~~] 04 12 PM Rsreemenl TM1UrS ton Caw[y WasM1 in9f on C[TV OF VELM (IIIIIII III IIIIII VIII IIII IIIIII VIII IIII IIIIIII IIIIII IIII (VII VIII IIIIIII III VIII VIII IIII IIII Stormwater Program Guidance Manual Vn/uma //' of the soil and can result in reduced plant growth, erosion; and contamination of surface water. 4. If animals must be kept in a pasture over the winter, a small "sacrifice" area should be used for feeding and watering. This will limit the amount of land disturbed and reduce the area of pasture that will need reseeding. The sacrifice area should be located away from streams or standing water. Portable electric fencing can be used to keep the animals in this temporary area. 5. Always limit the number of animals pastured based on the amount of land available and pasture productivity. The local Conservation District can offer advice on the proper stocking rate for your land. The smaller the acreage grazed, the 8reater the chance for vegetative destruction, even when hay is provided. 6. Intensive livestock use may necessitate reseeding of a pasture every two to three years to optimize production and minimize the chance of erosion. Ideal renovation entails plowing the pasture and sowing an annual crop such as corn, oats, or annual rye grass for one year and reseeding again the following year. Animals should be kept off the new seeding for the first year. Fields may be hayed towards the end of the first growing year. 7. If planting an alternate crop for one year is not possihle, some coverage and plant species improvement can be achieved by disking the pasture and reseeding. 8. Overgrazing can also be avoided by dividing the pasture into three or more units and establishing a grazing rotation period that allows foliage three to four weeks of regrowth between grazing periods. A portable electric fence can also be used in this situation. 9. The Sal Conservation Service and the County Conservation District can provide growers with details of these practices.

The storage site should be an area well away from creeks, ditches, marshes, and ponded or flowing water, where oft- site runoff cannot mix with manure and where seepage from manure cannot enter surface water. 2. Stored manure should be covered with either a roof'or plastic sheeting to prevent the entry of rainwater.. Rooftop runoff from the manure storage area should be diverted away from the storage area by using gutters and downspouts. This clean water can be infiltrated back into the ground to recharge ground water. BMPS III-RI-15 and III- RI-16 in Volume III of the Stormwater Management Manual far the Puget Sound Basin give design criteria for roof downspout infiltration systems. 3. Small watercourses adjacent to the manure storage area should be redirected or enclosed. To do any work in or on streambanks, a short-term wafer quality modification permit or a hydraulic permit approval may be required.
