The overall Bressi Ranch Development is located in the City of Carlsbad and is bounded by: 1) Palomar Airport Road to the north, 2) Melrose Drive to the east, 3) El Camino Real to the west, and 4) Poinsettia Drive to the south. Within the Bressi Ranch Development, this project is comprised of five planning areas, creating an irregular-shaped site that is bounded by: 1) Palomar Airport Road to the north, 2) El Camino Real to the west, 3) Open Space 1, Alicante Road, and Melrose Drive to the east, and 4) Town Garden Road and Gateway Road to the south. The vicinity and site maps are available in Appendix 2. The total project site is 155 acres and currently consists of mass graded pads per the Bressi Ranch Mass Grading project. This project covers the precise grading and construction of the storm drain improvements, associated roadways, and utilities to support 2,160,000 square feet of industrial space for future development. This WQTR does not cover the development of the individual industrial lots. Each industrial lot shall be responsible for complying with the City of Carlsbad Storm Water Standards by implementing appropriate site design, source control, and treatment BMPs. In developing the individual industrial lots, the BMPs identified in the Industrial Concept Water Quality Plan for Bressi Ranch, TM CT 00-06 (ProjectDesign Consultants, April 2002) are recommended for priority consideration.

Impaired Water Bodies Section 303(d) of the Federal Clean Water Act (CWA, 33 USC 1250, et seq., at 1313(d)), requires States to identify and list waters that do not meet water quality standards after applying certain required technology-based effluent limits (impaired water bodies). The list is known as the Section 303(d) list of impaired waters. The proposed project is not directly tributary to a 303(d) listed water body. The closest impaired water body is the Pacific Ocean Shoreline, San Marcos HA, which is 303(d) listed for bacteria. TAWater ResourcesWater Quality\_Projects\2737-Bressi lndustrialWQTR\2737-WQTR_3.doc -5 - In addition to the Section 303(d) list of impaired waters, the State of California also identifies waters of concern that may be included on the 303(d) list in the very near future. These waters have some indications that they are impaired, but there is currently insufficient data to meet the requirements for inclusion on the 303(d) list of impaired waters. This Hst is known as the Monitoring List (2002). The proposed project is not directly tributary to a Monitoring List (2002) water body. The closest Monitoring List (2002) water body is the Aqua Hedionda Lagoon, which is listed for copper and selenium. Watershed Pollutants of Concem The proposed project is located within the Carlsbad Watershed. According to the Carlsbad Watershed Urban Runoff Management Program, the pollutants of concern for the Watershed are bacteria, diazinon, sediment, total dissolved soilds, and nutrients. Conditions of Concern A drainage study was conducted by a California Registered Civil Engineer (RCE) to identify the conditions of concern for this project. The drainage calculations for existing conditions are available in the ProjectDesign Consultants Drainage Report for the Bressi Ranch Mass Grading & Backbone Improvements, dated February 2003. Drainage calculations for proposed conditions are available in the ProjectDesign Consultants Drainage Report for Bressi Ranch PA's 1-5 Industrial Area Project, CT 02-15, dated September 2004. Following is the summary of findings from the studies: • Drainage Pattems: Under existing conditions, most of the runoff from the planning areas sheet flows to the southwest and into desilting basins before entering the onsite storm drain system for Bressi Ranch Development. Part of Planning Area (PA) 3 discharges directly into the city storm drain system on El Camino Real, and PA 1 and PA 2 discharge into a natural canyon within Open Space 1 (OSI). The rest of the areas discharge into backbone storm drain system of Bressi Ranch Development, which T:\Waler ResourcesWater Quality\_Projecl.';'i2737-Bressi todustrial\WQTR\2737-WQTR_3.doc -6- empties into two detention basins before entering the unnamed creek and natural canyon (OSI), which eventually discharges into San Marcos Creek. Under proposed conditions, the storm water from each area will sheet flow to onsite inlets and into the onsite storm drain system. The onsite storm drain system will connect into the city storm drain system or into the Bressi backbone storm drain system, which discharges into two detention basins before leaving the site. Discharge from the detention basins enters a natural canyon (OSI) and an unnamed creek, ultimately discharging into San Marcos Creek. • Soil Conditions and Imperviousness: The project area consists of soil group D. Under the existing mass graded conditions, the project area is 5% impervious and the runoff coefficient is 0.55. Under the ultimate proposed conditions (industrial land use), the project area will be 90% impervious and the overall runoff coefficient is expected to be 0.90. For purposes of this WQTR, the proposed conditions imperviousness and runoff coefficient will be approximately the same as existing conditions. • Rainfall Runoff Characteristics: Under existing conditions, the project area generates approximately 261.8 CFS (lOO-year storm) of storm water runoff. Under the ultimate proposed conditions (industrial land use), the site will generate approximately 626.5 CFS (lOO-year storm) of storm water mnoff. • Downstream Conditions: There is no expected adverse impact on downstream conditions, as existing drainage pattems will be maintained. The amount of water entering the city storm drain system on El Camino Real will not increase from existing conditions. The detention basins at the southem ends of the Alicante Street and El Fuerte Street storm drains will reduce the impact of the increase in storm water flow due to the development, and the design of the outfall pipes will protect against high velocity erosion. Water quality will improve throughout the development due to the implementation of site design, source control, and treatment BMPs.

STORM WATER BEST MANAGEMENT PRACTICES The City Storm Water Standards Manual (Section III.2) requires the implementafion of applicable site design, source control, project-specific, and structural treatment control BMPs. This WQTR covers the precise grading and construction of the storm drain improvements, associated roadways, and utilities to support 2,160,000 square feet of industrial space for future development. This WQTR does not cover the development of the individual industrial lots. Each industrial lot shall be responsible for complying with the City of Carlsbad Storm Water Standards by implementing appropriate site design, source control, and treatment BMPs. In developing the individual industrial lots, the BMPs identified in the Industrial Concept Water Quality Plan for Bressi Ranch, TM CT 00-06 (ProjectDesign Consultants, April 2002) are recommended for priority considerafion. The storm water BMPs identified in this report apply to the completion of precise grading and construcfion of storm drain improvements, associated roadways, and utilities. Further site design, source control, project-specific, and structural treatment control BMPs shall be identified when development of the industrial lots is proposed. Site Design and Source Control BMPs The project addressed the site design and source control BMPs required by the City Storm Water Standards (in.2.A and III.2.B) as follows: • Maintain Pre-Development Rainfall Runoff Characteristics o Minimize impervious footprint - This project covers the precise grading and construction of the storm drain improvements, associated roadways, and utilities within Planning Areas 1-5. The impervious footprint of this work is dictated by City standards for street widths. TAWater ResourcesWater Quality\_Projects\2737-Brcssi lndustrialWQTR\2737-WQTR_3.doc -9- o Conserve natural areas - Natural drainage systems shall be used to the maximum extent practicable. - Selection of the location for the industrial planning areas in the Bressi Ranch Master Community has located the industrial areas on the least environmentally sensitive portions of the site, to the maximum extent practicable. o Minimize directly connected areas - Landscaping will be included on the 40 individual lots. It will be the responsibility of the Developer(s) of those lots to comply with the City Storm Water Standards by draining rooftops and other impervious areas into adjacent landscaping. The landscaping currently proposed with this project is for stabilizafion of the slopes. o Maximize canopy interception and water conservation - No landscaping is included in this project; therefore, this site design BMP is not applicable to this project. Protect Slopes and Channels o All slopes will be stabilized with hydroseed or equivalent erosion control measures. o All outfalls will be equipped with an energy dissipation device and/or a riprap pad to prevent high velocity erosion. Design Outdoor Materials Storage Areas to Reduce Pollution Introduction TAWater ResourcesWater Quality\_Projects\2737-Bressi liidustrialWQTR\2737-WQTR_3.doc -10- o This project covers the precise grading and construction of the storm drain improvements, associated roadways, and utilities within Planning Areas 1-5. There are no outdoor materials storage areas included. • Design Trash Storage Areas to Reduce Pollution Introduction o This project covers the precise grading and construction of the storm drain improvements, associated roadways, and utilities within Planning Areas 1-5. There are no trash storage areas included. • Provide Storm Water Conveyance System Stenciling and Signage o When curbs/sidewalks are installed, all storm drain inlets and catch basins within the project area shall be stenciled, labeled, or stamped with prohibitive language (such as: "NO DUMPING - I LIVE DOWNSTREAM") and graphical icons to discourage illegal dumping, according to City approved designs. • Use Efficient Irrigation Systems and Landscape Design o Rain shutoff devices shall be employed to prevent irrigation during precipitation, consistent with the Carlsbad Landscape Manual. o Irrigation systems shall be designed to each landscape area's specific water requirements, consistent with the Carlsbad Landscape Manual. • Employ Integrated Pest Management Principles o This project covers the precise grading and construction of the storm drain improvements, associated roadways, and utilities within Planning Areas 1-5. There will be no pesticide use. TAWater ResourcesWater Quality\_Projects\2737-Bressi Ii)dustrial\WQTR\2737-WQTR_3.doc - 11 - Project-Specific BMPs The City Storm Water Standards Manual requires specific BMPs if the project includes private roads, residential driveways and guest parking, dock areas, maintenance bays, vehicle and equipment wash areas, outdoor processing areas, surface parking areas, non-retail fueling areas, or steep hillside landscaping. The future development of the industrial space may include components that require project-specific BMPs. When development plans for this stage of the project are developed, they shall comply with the City Storm Water Standards. Structural Treatment BMPs The storm water BMPs identified in this report apply to the completion of precise grading and construction of storm drain improvements, associated roadways, and utilities. The treatment BMPs utilized for this project shall be desilting basins that will be operated and maintained until the industria] space is developed. The desilting basins shall be designed per the NPDES General Permit for Storm Water Discharges Associated with Construction Activity. This WQTR does not cover the development of the individual industrial lots. Each industrial lot shall be responsible for complying with the City of Carlsbad Storm Water Standards by implementing appropriate site design, source control, and treatment BMPs. In developing the individual industrial lots, the BMPs identified in the Industrial Concept Water Quality Plan for Bressi Ranch, TM CT 00-06 (ProjectDesign Consultants, April 2002) are recommended for priority consideration. TAWater ResourcesWater Ouality\_Projects\2737-Bressi lndustrialWOTR\2737-WQTR_3.doc - 12- 5. PROJECT BMP PLAN IMPLEMENTATION This section identifies the recommended BMP options that meet the applicable storm water and water quality ordinance requirements. This includes incorporating BMPs to minimize and mitigate for runoff contamination and volume from the site. The plan was developed per the proposed roadway and lot layout/density associated with the site. Construction BMPs During construcfion, BMPs such as desilting basins, silt fences, sand bags, gravel bags, fiber rolls, and other erosion control measures may be employed consistent with the NPDES Storm Water Pollution Prevention Plan (SWPPP). The objectives ofthe SWPPP are to: • Identify all pollutant sources, including sources of sediment that may affect the water quality of storm water discharges associated with construction activity from the construction site; • Identify non-storm water discharges; • Identify, construct, implement in accordance with a time schedule, and maintain BMPs to reduce or eliminate pollutants in storm water discharges and authorized non-storm water discharges from the construction site during constmction; and • Develop a maintenance schedule for BMPs installed during construcfion designed to reduce or eliminate pollutants after construction is completed (post-construction BMPs). Recommended Post-Construction BMP Plan PDC has identified a recommended water quality BMP plan for the Bressi Ranch Industrial Planning Areas 1, 2, 3, 4, and 5 Project, covering only the complefion of precise grading and construction of storm drain improvements, associated roadways, and utilities. TAWater ResourcesWater Quality\_Projects\2737-Bressi bdustrialWQTR\2737-WQTR_3.doc - 13 - The recommended post-construction BMP plan includes site design, source control, and treatment BMPs. The site design and source control BMP options include maintaining pre- developed rainfall runoff characteristics, protection of slopes and channels, and inlet stenciling and signage. The treatment BMP selected for this stage ofthe project is continued operation and maintenance of desilting basins until the industrial space is developed. Operation and Maintenance Plans The City Municipal Code requires a description of the long-term maintenance requirements of proposed BMPs and a description of the mechanism that will ensure ongoing long-term maintenance. The Sares Regis Group is responsible for continued operation and maintenance of the desilting basins until the industrial space is developed.

Use temporary concentrated flow conveyance controls to divert runoff from undisturbed areas away from the desilting basin. • Desilting basins shall be designed to have a capacity equivalent to 100 cubic meters of storage (as measured from the top ofthe basin to the principal outlet,) per hectare of contributory area. This design is less than the required to capture the 0.01 mm particle size but larger than that required to capture particles 0.02 mm or larger. • The length of the basin shall be more than twice the width of the basin; the length shall be determined by measuring the distance between the inlet and the outlet. • The depth must be no less than one (1) meter nor greater than 1.5 m. • Basins with an impounding levee greater than 1.5 m tall, measured from the lowest point to the impoimding area to the highest point ofthe levee, and basins capable of impounding more than 1000 cubic meters (m^), shall be designed by a professional Civil Engineer registered with the state of Califomia. The design must be submitted to the Resident Engineer (RE) for approval at least 7 days prior to the basin constraction. The design shall include maintenance requirements, including sediment and vegetation removal, to ensure continuous function of the basin outlet and bypass stractures. • Design and locate desilting basins so that they can be maintained. Constract desilting basins prior to the rainy season and constraction activities. • Desilting basins, regardless of size and storage volume, shall include features to accommodate overflow or bypass flows that exceed the design storm event. The calculated basin volume and proposed location shall be submitted to the RE for approval at least 3 days prior to the basin constraction. • Basuis shall be designed to drain within 72 hours following storm events. • The outflow from the desilting basin shall be provided with outiet protection to prevent erosion and scouring ofthe embankment and chaimel. • Basin shall be located: (1) by excavating a suitable area or where a low embankment can be constracted across a swale, (2) where post-constraction (pennanent) detention basins will be constracted, (3) where failure would not cause loss of life or property damage, and (4) where the basuis can be Caltrans Storm Water Quality Handbooks Construction Site Best Management Practices Manual SC-2 Desilting Basin 2 of 8 Cafinms November 2000 Desilting Basin SC-2 Qj/trans maintained on a year-round basuis to provide access for maintenance, including sediment removal and sediment stockpiling in a protected area, and to maintain the basin to provide the required capacity. Areas imder embankments, stractural works, and desilting basin must be cleared, stripped of vegetation in accordance with Standard Specifications Section 16 - Clearing and Grabbing. Earthwork shall be in accordance with Standard Specifications Section 19 - Earthwork. Confractor is specifically directed to Section 19-5 , "Compaction", and 19-6, "Embankment Constraction". Basin inlets shall be located to maximize travel distance to the basin outiet. Rock or vegetation shall be used to protect the basin inlet and slopes against erosion. A forebay, constracted upstream ofthe basin may be provided to remove debris and larger particles. Principal outlet shall consist of a corragated metal, high density polyethylene (HDPE), or reinforced concrete riser pipe with dewatering holes and an anti-vortex device and trash rack attached to the top ofthe riser, to prevent floating debris from flowing out ofthe basin or obstracting the system. This principal stracture shall be designed to accommodate the inflow design storm. Stracture shall be placed on a fmn, smooth foundation with the base securely anchored with concrete or ofher means to prevent floatation. Attach riser pipe (watertight connection) to a horizontal pipe (banel) which extends through the embankment to toe of fill. Provide anti-seep collars on the banel. Cleanout level shall be clearly marked on the riser pipe. Avoid dewatering of groundwater to the desilting basin during the rainy season. Insignificant quantities of accumulated precipitation may be dewatered to the desilting basin unless precipitation is forecasted within 24 hours. Chain link fencing shall be provided around each desilting basin to prevent unauthorized entry to the basin or if safety is a concem. Fencing shall be in accordance with Standard Specifications Section 80 - Fencing. Caltrans Storm Water Quality Handbooks Construction Site Best Management Practices Manual Desilting Basin SC-2 November 2000 3 of 8 SC-2 Desilting Basin One of the dewatering configurations shown below for the principal outlet may be used. The Confractor shall verify that the outiet is properly designed to handle the design and peak flows. Outlet #1, See Page 6 Perforate the top one-third of the riser with 13 mm (0.5 in) diameter holes spaced 200 mm (8 in) vertically and 250 mm (10 in) - 300 mm (12 in) horizontally. Place 19 mm (0.75 in) gravel over perforated holes to approximately 50 mm (2 in) minimum thickness to assist in prevention of clogging of dewatering holes. Gravel will naturally settle into a cone surrounding the riser pipe. Outlet #2, See Page 7 Perforate the lower one-half of the riser pipe with 13 mm (0.5 in) diameter holes spaced approximately 75 mm (3 in) apart, in each outside valley (corragated metal pipe). Place 19 mm (0.75 in) gravel over perforated holes to approximately 50 mm (2 in) minimum thickness to assist in prevention of clogging of dewatering holes. Gravel will naturally settle into a cone surrounding the riser pipe. Outlet #3, See Page 8 Provide two 25 mm (1 in) diameter holes above the sediment storage volume on opposites sides of the non-perforated riser pipe. This will typically provide sufficient detention time for basins to drain approximately 4 ha (10 ac). Constract an emergency spillway to accommodate flows not carried by the principal spillway. Spillway shall consist of an open channel (earthen or vegetated) over undisturbed material (not fill) or constracted of a non-erodible riprap. Spillway confrol section, which is a level portion of the spillway channel at the highest elevation in the chaimel, shall be a minimum of 6 m (20 ft) in length.

The stenciled messages are generally a simple phrase to remind passersby thai the storm drains connect to local walert)odies and that dumping pollutes those waters. Some specify which waterbody the inlet drains to or name the , particular river, lake, or bay. Commonly stenciled messages include^ No Dumping. Drains to Water Source," "Drains to River," and "You Dump it You Drink it No Waste Here." Pictures can also be used to convey the message, including a shrimp, common game fish, or a graphic depiction of PatJ"'^^^ drain to waterbody. Communities with a large Spanish-speaking population might wish to develop stencils in both English and Spanish, or use a graphic alone. TOP Applicability Munictpalities can undertake stenciling projects throughout the entire community, especially in areas with sensith/e waters or where trash, nutnents, ^ Wological oxygen demand have been identified as high pnonty poiiutants. However regardless of the condition of the waterbody, the signs raise awareness about the connection between storm drains and receiving waters and they help deter littering, nutrient overenrichment, and other Practices that contribute to nonpoint source pollution. Municipalities shouid identify a subset of drains to stendl because there might be hundreds of inlets; stencthng all of them would be prohibitively expensive and might actually dimmish the effect ofTe misage on the public. The drains should be carefully selected to send the message to the maximum number of citizens {for example tn areas of high pedestrian traffic) and to target drains ieading to waterbodies where illegal dumping has been identified as a source of pollution. Implementation Municipalities can implement storm drain stenciling prograrns in two ways- In some cases, cities and towns use their own public works staff to do the labeling Some municipalities feel that having their own crews do lhe work Menu of BMPs information Menu of BMPs Home Piihlic Education & Outreach on Storm Water Impacts Public Involvement & Participation IHIcit Discharge Detection & Elimination Construction Site Storm Water Runoff Control Po.si-Construction Storm Water Management in New Deveiopment & Redevelopment Pollution Prevention & Good Housekeepina for Municipal Operations Downloadable Files Measurable Goals The documents on this sile are best viewed with Acrobal 5.0 http://cfpub.epa.gov/npdes/slormwater/menuofbmps/invoL6.cfm 2/21/2003 EPA - Public Involvement/Participation f^g^ 2 ot 6 produces better results and eliminates liability and safety concerns. More commonly, stenciling projects are conducted by volunteer groups in cooperation with a municipality. In such an arrangement, volunteer groups provide the labor and the municipality provides supplies, safety equipment, and a map and/or directions to the drains to be stsncited. The benefits of using volunteers are lower cost and increased public awareness of storm water pollutants and their path to waterbodies. A municipality can establish a program to comprehenswely address storm drain stenciling and actively recruit volunteer groups to help, or the municipality can facilitate volunteer groups that lake the initiative to undertake a stenciling project. Whether the municipality or a volunteer group initiates a stenciling project, the muncipaiity should designate a person in charge of the slorm drain stenciling program. Many municipalities will designate a person from the pubic works or water quality department to coordinate stenciling projecis by volunteer groups. Because these programs depend heavily on volunteer labor, organizers and coordinators shoutd be skilled in recruiting, training, managing, and recognizing volunteers. Coordination activities include providing • Stenciling kits containing all materials and tools needed to carry out a slenciling project • A map of the storm drains to be stenciled • Training for volunteers on safety procedures and on the technique for using stencils or affixing signs • Safety equipment (traffk: cones, safety vests, masks and/or goggles for spray paint, and gloves if glue is used) • Incentives and rewards for volunteers (badges, T-shirts, certificates). The coordinator might also wish to provide pollulant-tracking forms to collect data on serious instances of dumping. Participants in slorm drain slerwiling projects can be asked to note storm drains that are clogged with debris or show obvious signs of dumping. This enables city crews to target cleanup efforts. Volunteers should be instructed on what kinds of pollutants to look for and how to fill oul data cards. Volunteers also should record the locations of all storm drains labeled during the project, so the cily can keep track. Additionally, the participants should convene after the event to talk about what they have found. Their reaclions and impressions can help organizers improve future stenciling projects. If a municipality chooses to initiate a storm drain stenciling program and solicit the help of volunteer organizations, they can advertise Ihrough a variety of channels. Outreach strategies include • Distributing pamphlets and brochures to area service organizations • Placing articles in local magazines • Taking out newspaper ads • Placing an environmental insert in the local newspaper • Making presentations at community meetings • Developing pubiic service announcements for radio • Creating a web site with background and contact informaiion as well as photos and stories from past stenciling events (the references section contains a list of storm drain slenciling web sites from communities across the country) • Using word-of-mouth communications about the program. Newspapers can be notified to get advance coverage of a planned slenciling event. Newspapers might choose to cover the evenl itself as an environmental feature stor/ lo further public awareness. A news release issued for the day of the event can draw TV and/or newspaper coverage. Public service announcements made before the event also will help to reinforce lhe message. Additionally, some municipalities can have volunteers http://cfpub.epa.gov/npdes/stonnwater/menuofbmps/invol_6.cfm 2/21/2003 EP.A - Public Involvement/Participation P^g^ 3 of 6 distribute door hangers in the targeted neighborhoods to notify residents thai storm drain stenciling is taking place. The hangers explain the purpose of the projecl and offer tips on how citizens can reduce urban runoff in general. For any volunteer project to be successful, volunteers must feel they have done something worthwhile. Communities active in slorm drain stenciling have developed a variety of ways to recognize volunteers, including • Providing each participant with a certificale of appreciation and/or letter of thanks stoned by the mayor • Distributinglogo items such as T-shirts, hats, badges, plastic water bottles, or other items to participants before or after the event • Holding a picnic or smail party after the event with refreshments donated by a local business • Providing coupons for free pizza, hamburgers, ice cream, or movies donated by local merchants • Taking pictures of slenciling teams before, during, and after the event lo create a pictorial record of volunteers' activity. Since stenciling projects take place on city streets, volunteer safety is of utmost importance. The city might wish to designate lower-traffic residential areas as targets for volunteer stenciling and provide safety equipmeni and training. Mosl programs require that stenciling be done in teams, with al least one person designated to watch for traffic. Adult supervision is needed when volunteer are school cWWren or members of youth groups. Most cities also require participating volunteers (or their parente) to sign a waiver of liability. An attomey for the municipality shoutd be consulted lo determine what liability exists and how to handle this issue. Materials Most communities use slencils and paint to label their storm drains. Some communities stencil directly onto the curb, streel, or sidewalk, while others first paint a white background and then stencil over it. The most commonly used stencils are made of Mylar, a flexible plastk; material that can be cleaned and reused many times. However, stencils can also be made from cardboard, aluminum, or other malerial. The reference seclion lists web sites where stencils can be purchased. Storni drain messages can be placed flat against the sidewalk surtace just above the storm drain inlet, while olhers are placed on the curb facing the street or on the street itself, either just upstream of the storm drain or on the street in front of the drain. However, messages placed on the street might wear out sooner. Paint or ink can be sprayed on or applied by brush and roller. Spray paint is quickest and probably the easiest to apply neatly. Regions that do not meet federal air-quality standards should avoid using spray paints, since many contain air-polluting pnspellants. If is recommended lo use "environmentally friendly" paint lhal contains no heavy metals and is low in volatile organic compounds. Alternatives to painted messages inciude pennanent signs made of aluminum, ceramic, plaslic, or other durable materiais. These signs last longer than stenciled messages and need onfy glue to affix them to stonn drain inlets. They might also be neater and easier to read from a distance. Tiles or plaques can be dislodged by pedestrian traffic if they are disturtied before the glue dries. Benefits http://cfpub.epa.gov/npdes/stormwater/menuofbmps/invol_6.cfm 2/21/2003 EPA - Public InvolvcmenL'Parlicipalion Page 4 of 6 Storm drain stenciling projecis offer an excellent opportunity to educate the public about fhe link between the storm drain system and drinking water quality. In addition to the labeled storm drains, media coverage of the program or sisnciling event can increase public awareness of slorm waler issues. Volunteer groups can provide additional benefits by picking up trash near the stenciled storm drains and by noting where nmintenance is needed. Additionally, stenciling projects can provide a lead-in to volunteer monitoring projects and increase community participation in a variety of other storm water-related activities. LimitatjotiS A storm drain stenciling program is generally effective, inexpensive, and easy lo implement. However, larger communities can have many stonn drain inlets, so volunteer coordinators need lo be skilled at recruiting and organizing the efforts of volunteers to provide adequate coverage over large areas. Safety consideraiions mighl also limit stenciling programs in areas where traffic congestion is high. Other environmental considerations such as the use of propellants in spray paint in areas that do not meet air quality standards should be taken into account. Finally, stencils wil! require repainting after years of weather and traffic, and tiles and permanent signs might need replacement if they are improperly installed or subject to vandalism. Effectiveness By raising public awareness of urban runoff, storm drain stenciling programs should discourage practices that generate nonpoint source pollutants. As with any publk; educalion prefect, however, it is diffrcult to precisely measure the effect thai slorm drain stenciling programs have on human behavior. Nor is it easy to measure reductions in certain components of urban runoff, which by definition is diffuse in origin. Some municipalities attempt lo assess the effectiveness of storm drain stenciling programs by periodically examining water samples from targeted stoim drain outfalls (places where storm drains empty into a waterbody). If the slorm drains leading to a particular ouHall have been labeled, and if the levels of pollutants from that outfall decline after the stencils were put in place, one can assume the labeling has had some deterrent effect. This monitoring can be conducted by the same volunteer groups that stenciled the drains and can be incorporaied into existing volunteer monitoring programs or can initiate the developmenl of a new program. Cities also infer stenciling program success from increases in lhe volume of used motor oil delivered to used-oil recycling centers. Others measure success in terms of how many drains are stenciled and the number of requests received by volunteer groups lo participate in the program. They can also lake Inio consideration the number of cleanups conducted by the city as a result of reports made by volunteers. Costs Mylar stencils cost about 45 cents per linear inch and can be used for 25 to 500 stencilings, depending on whether paint is sprayed or applied with a brush or roller. Permanent signs are generally more costly: ceramic tiles cost $5 lo $6 each and metal stencils can cost $100 or more.
