"' Printed on Recycled Paper PA2021-094 Tips for Residential Pool, Landscape and Hardscape Drains Pool Maintenance All pool water discharged to the curb, gutter or permitted pool drain from your property must meet the following water quality criteria: ■ The residual chlorine does not exceed 0.1 mg/L (parts per million). ■ The pH is between 6.5 and 8.5. ■ The water is free of any unusual coloration. ■ There is no discharge of filter media or acid cleaning wastes. Some cities have ordinances that do not allow pool water to be discharged to the storm drain. Check with your city. Landscape and Hardscape Drains The following recommendations will help reduce or prevent pollutants from your landscape and hardscape drains from entering the street, gutter or storm drain. Unlike water that enters the sewer (from sinks and toilets), water that enters a landscape or hardscape drain is not treated before entering our creeks, rivers, bays and ocean. Household Activities ■ Do not rinse spills of materials or chemicals to any drain. ■ Use dry cleanup methods such as applying cat litter or another absorbent material, then sweep it up and dispose of it in the trash. If the material is hazardous, dispose of it at a Household Hazardous Waste Collection Center (HHWCC). For locations, call (714) 834-6752 or visit www.oclandfills.com. ■ Do not hose down your driveways, sidewalks or patios to your landscape or hardscape drain. Sweep up debris and dispose of it in the trash. ■ Always pick up after your pet. Flush waste down the toilet or dispose of it in the trash. ■ Do not store items such as cleaners, batteries, automotive fluids, paint products, TVs, or computer monitors uncovered outdoors. Take them to a HHWCC for disposal. Yard Maintenance ■ Do not overwater. Water by hand or set automated irrigation systems to reflect seasonal water needs. ■ Follow directions on pesticides and fertilizers (measure, do not estimate amounts) and do not use if rain is predicted within 48 hours. ■ Cultivate your garden often to control weeds and reduce the need to use chemicals. Vehicle Maintenance ■ Never pour oil or antifreeze down your landscape or hardscape drain. Recycle these substances at a service station, a waste collection center or used oil recycling center. For locations, contact the Used Oil Program at 1-800- CLEANUP or visit www.CLEANUP.org. ■ Whenever possible, take your vehicle to a commercial car wash. ■ If you do wash your vehicle at home, do not allow the washwater to go down your landscape or hardscape drain. Instead, dispose of it in the sanitary sewer ( a sink or toilet) or onto an absorbent surface such as your lawn. ■ Use a spray nozzle that will shut off the water when not in use. PA2021-094 Do your part to prevent water pollution in our creeks, rivers, bays and ocean. Clean beaches and healthy creeks, rivers, bays, and ocean are important to Orange County. However, many common household REMEMBER THE WATER IN YOUR STORM DRAIN IS Nor TREATED BEFORE Ir ENTERS OuR WATERWAYS activities can lead to water pollution if you're not careful. Litter, oil, chemicals and other substances that are left on your yard or driveway can be blown or washed into storm drains that flow to the ocean. Over-watering your lawn and washing your car can also flush materials into the storm drains. Unlike· water in sanitary sewers ( from sinks and toilets), water in storm drains is not treated. You would never pour soap, fertilizers or oil into the ocean, so don't let them enter streets, gutters or storm drains. Follow the easy tips in this brochure to help prevent water pollution. For more information, please call the Orange County Stormwater Program at 1-877-89-SPILL (1-877-897-7455) or visit www.ocwatersheds.com To report a spill, call the Orange County 24-Hour Water Pollution Problem Reporting Hotline 1-877-89-SPILL (1-877-897-7455).

Set irrigation systems to reflect seasonal water needs. If water flows off your yard and onto your driveway or sidewalk, your system is over-watering. ■ Mulch clippings or leave them on the lawn. If necessary, dispose in a green waste container. ■ Cultivate your garden often to control weeds. Washing and Maintaining Your Car ■ Take your car to a commercial car wash whenever possible. ■ Choose soaps, cleaners, or detergents labeled "non-toxic," "phosphate free" or "biodegradable." Vegetable and citrus- based products are typically safest for the environment, but even these should not be allowed into the storm drain. ■ Shake floor mats into a trash can or vacuum to clean. ■ Do not use acid-based wheel cleaners and "hose off" engine degreasers at home. They can be used at a commercial facility, which can properly process the washwater. ■ Do not dump washwater onto your driveway, sidewalk, street, gutter or storm drain. Excess washwater should be disposed of in the sanitary sewers ( through a sink, or toilet) or onto an absorbent surface like your lawn. ■ Use a nozzle to turn off water when not actively washing down automobile. ■ Monitor vehicles for leaks and place pans under leaks. Keep your car well maintained to stop and prevent leaks. ■ Use cat litter or other absorbents and sweep to remove any materials deposited by vehicles. Contain sweepings and dispose of at a HHWCC. ■ Perform automobile repair and maintenance under a covered area and use drip pans or plastic sheeting to keep spills and waste material from reaching storm drains. ■ Never pour oil or antifreeze in the street, gutter or storm drains.

"' Piinted on Recycled Paper ,~11,, PA2021-094 Key Steps to Follow: Steb J: Correctly identify the pest (insect, weed, rodent, or disease) and verify that it is actually causing the problem. a This is important · because beneficial insects are often mistaken for pests and sprayed with pesticides needlessly. Three life stages of the common lady Consult with a beetle, a beneficial insect. C "fi d N ert:J. e ursery Professional at a local nursery or garden center or send a sample of the pest to the Orange County Agricultural Commissioner's Office. Determine if the pest is still present -even though you see damage, the pest may have left. Step 2: Determine how many pests are present and causing damage. Small pest populations may be controlled more safely using non- pesticide techniques. These include removing food sources, washing off leaves with a strong stream of water, blocking entry into the home using caulking and replacing problem plants with ones less susceptible to pests. ~ Univ_~sity_of California Coopmtm limmioo Integrated Pest Management (1PM) usually combines several least toxic pest control methods for long-term prevention and management of pest problems without harming you, your family, or the environment. Steb 3: If a pesticide must be used, choose the feast toxic chemical. Obtain information on the least toxic pesticides that are effective at controlling the target pest from the UC Statewide Integrated Pest Management (1PM) Program's Web site at www.ipm.ucdavis.edu. Seek out the assistance of a Certified Nursery Professional at a local nursery or garden center when selecting a pesticide. Purchase the smallest amount of pesticide available. Apply the pesticide to the pest during its most vulnerable life stage. This information can be found on the pesticide label. Step 4: Wear appropriate protective clothing. Follow pesticide labels regarding specific types of protective equipment you should wear. Protective clothing should always be washed separately from other clothing. Steb 5: Continuously monitor external conditions when applying pesticides such as weather, irrigation, and the presence of children and animals. Never apply pesticides when rain is predicted within the next 48 hours. Also, do not water after applying pesticides unless the directions say it is necessary. Apply pesticides when the air is still; breezy conditions may cause the spray or dust to drift away from your targeted area. In case of an emergency call 911 and/ or the regional poison control number at (714) 634-5988 or (800) 544-4404 (CA only). For general questions you may also visit www.calpoison.org. Step 6: In the event of accidental spills, sweep up or use an absorbent agent to remove any excess pesticides. Avoid the use of water. Be prepared. Have a broom, dust pan, or dry absorbent material, such as cat litter, newspapers or paper towels, ready to assist in cleaning up spills. Contain and clean up the spill right away. Place contaminated materials in a doubled plastic bag. All materials used to clean up the spill should be properly disposed of according to your local Household Hazardous Waste Disposal site. Step 7: Properly store and dispose of unused pesticides. Purchase Ready-To- U se (RTU) products to avoid storing large concentrated quantities of pesticides. Store unused chemicals in a locked cabinet. Unused pesticide chemicals may be disposed of at a Household Hazardous Waste Collection Center. Empty pesticide containers should be triple rinsed prior to disposing of them in the trash.

If you have other suggestions, please contact your city's stormwater representatives or call the Orange County Stormwater Program. ,. "' Printed on Recycled Paper ~~:-~:i:,:? .. .., PA2021-094 Home improvement projects can cause significant damage to the environment. Whether you hire a contractor or work on the house yourself, it is important to follow these simple tips while renovating, remodeling or improving your home: General Construction ■ Schedule projects for dry weather. ■ Keep all construction debris away from the street, gutter and storm drain. ■ Store materials under cover with temporary roofs or plastic sheets to eliminate or reduce the possibility that rainfall, runoff or wind will carry materials from the project site to the street, storm drain or adjacent properties. Building Materials ■ Never hose materials into a street, gutter or storm drain. ■ Exposed piles of construction material should not be stored on the street or sidewalk. ■ Minimize waste by ordering only the amount of materials needed to complete the job. ■ Do not mix more fresh concrete than is needed for each project. ■ Wash concrete mixers and equipment in a designated washout area where the water can flow into a containment area or onto dirt. ■ Dispose of small amounts of dry excess materials in the trash. Powdery waste, such as dry concrete, must be properly contained within a box or bag prior to disposal. Call your local trash hauler for weight and size limits. Paint ■ Measure the room or object to be painted, then buy only the amount needed. ■ Place the lid on firmly and store the paint can upside- down in a dry location away from the elements. ■ Tools such as brushes, buckets and rags should never be washed where excess water can drain into the street, gutter or storm drain. All tools should be rinsed in a sink connected to the sanitary sewer. ■ When disposing of paint, never put wet paint in the trash. ■ Dispose of water-based paint by removing the lid and letting it dry in the can. Large amounts must be taken to a Household Hazardous Waste Collection Center (HHWCC). ■ Oil-based paint is a household hazardous waste. All leftover paint should be taken toaHHWCC. ■ For HHWCC locations and hours, call (714) 834-6752 or visit www.oclandfills.com. Erosion Control ■ Schedule grading and excavation projects for dry weather. ■ When temporarily removing soil, pile it in a contained, covered area where it cannot spill into the street, or obtain the required temporary encroachment or street closure permit and follow the conditions instructed by the permit. ■ When permanently removing large quantities of soil, a disposal location must be found prior to excavation. Numerous businesses are available to handle disposal needs. For disposal options, visit www.ciwmb.ca.gov/SWIS. ■ Prevent erosion by planting fast-growing annual and perennial grasses. They will shield and bind the soil. Recycle ■ Use a construction and demolition recycling company to recycle lumber, paper, cardboard, metals, masonry (bricks, concrete, etc.), carpet, plastic, pipes (plastic, metal and clay), drywall, rocks, dirt and green waste. ■ For a listing of construction and demolition recycling locations in your area, visit www.ciwmb.ca.gov/recycle. Spills ■ Clean up spills immediately by using an absorbent material such as cat litter, then sweep it up and dispose of it in the trash. ■ Immediately report spills that have entered the street, gutter or storm drain to the County's 24-Hour Water Pollution Problem Reporting Hotline at (714) 567-6363 or visit www.ocwatersheds.com to fill out an incident reporting form.

Periodically inspect and fix leaks and misdirected sprinklers. ■ Do not rake or blow leaves, clippings or pruning waste into the street, gutter or storm drain. Instead, dispose of green waste by composting, hauling it to a permitted landfill, or recycling it through your city's program. ■Use slow-release fertilizers to minimize leaching, and use organic fertilizers. ■ Read labels and use only as directed. Do not over-apply pesticides or fertilizers. Apply to spots as needed, rather than blanketing an en tire area. ■ Store pesticides, fertilizers and other chemicals in a dry covered area to prevent exposure that may result in the deterioration of containers and packaging. ■ Rinse empty pesticide containers and re-use rinse water as you would use the product. Do not dump rinse water down storm drains. Dispose of empty containers in the trash. ■ When available, use non-toxic alternatives to traditional pesticides, and use pesticides specifically designed to control the pest you are targeting. For more information, visit www.ipm.ucdavis.edu. ■ If fertilizer is spilled, sweep up the spill before irrigating. If the spill is liquid, apply an absorbent material such as cat litter, and then sweep it up and dispose of it in the trash. ■ Take unwanted pesticides to a Household Hazardous Waste Collection Center to be recycled.

Besides being a nuisance, pet t.J: waste can lead to water pollution, even if you live inland. During rainfall, pet waste left outdoors can wash into storm drains. This waste flows directly into our waterways and the ocean where it can harm human health, marine life and the environment. As it decomposes, pet waste demands a high level of oxygen from water. This decomposition can contribute to killing marine life by reducing the amount of dissolved oxygen available to them. Have fun with your pets, but please be a responsible pet owner by taking care of them and the environment. ■ Take a bag with you on walks to pick up after your pet. ■ Dispose of the waste in the trash or in a toilet.
