Local Storm Water Pollution Prevention Plan IV- Certification As the project owner, I certify that appropriate BMP's will be implemented to effectively minimize the negative impacts of this project's construction activities of storm water quality. The project contractor is aware that the selected BMP's must be installed, monitored, and maintained to ensure their effectiveness. The BMP's not selected for implementation are redundant or deemed not applicable to the proposed construction activities. Signed: Title: ^ Date: Local Storm Water Pollution Prevention Plan V- Post Construction Quality Management Possible Pollutant Sources The most economical and effective control of pollutants is achieved through good "housekeeping" practices and promotion of the need for compliance with the regulatory requirements. Potential pollutant sources within the site are discussed below: 1. Pesticides: Insecticides, Rodenticides and Herbicides. Recommended Control Measures: Application rates will conform to registered label directions. Many of these compounds are considered to be "dangerous wastes" and must be disposed of properly. Pesticide use will be consistent with the city management guidelines for use of fertilizers and pesticides (MGFP). In accordance with this MGFP, "pesticides are to be used only after recommendations from a state-licensed pest control advisor" (MGFP, Section 3.3.1). Furthermore, "pesticides are only to be applied by or under the direct supervision of a state-licensed or certified pesticide applicator or by workers with equivalent training" (MGFP, Section 3.3.2). 2. Nutrients: Fertilizers. Recommended Control Measures: Chemical runoff will be minimized by working fertilizers and liming materials into the soil a depth of 4 to 6 inches and by carefiil timing of the products' application with regard to weather conditions. Care will be exercised to use the minimum effective amounts of necessary phosphorous products. Fertilizer use will be consistent with the county MGFP. Non-Storm water Management It is anticipated that the routine maintenance of the site will result in discharges of water from the site other than storm water. BMPs and erosion control practices will be implemented to confrol these discharges to the maximum extent possible, in a manner consistent with the storm water discharge confrol measures. Water discharges from the site other than storm water are anticipated to result from: • Landscape irrigation • Water Pipe flushing (Fire Hydrants) 9 Local Storm Water Pollution Prevention Plan V- Post Construction Quality Management (cont'd) Targeted Pollutants This WQMP is designed to address the potential for pollution of waters within the City's storm drain system. The following is a list of pollutants reasonably expectS^to occur Jthin this site. These are categorized by their size, biological significance and solubility in water: A. Large-sized/biologically insignificant/water insoluble 1. bulk cellulose matter a. tree limbs, twigs, leaves, grass clippings b. paper, cardboard 2 fabric, packaging, container plastics B. Variable-sized^iologically insignificant/water insoluble 1. soil conditioners 2. basic soil constituents 3. inorganic dust falls from air pollutants C. Variable-sized^iologically nutritive/water soluble 1. natural and compound fertilizers a. nifrogen compounds b. phosphates c. potassium compounds 2. soluble air pollutants a. sulfiu: oxides b. nifrogen oxides c. ash 3. phosphate-base detergents 4. lawn and garden ash D. 4 lawn anu gaiucn aon , ,, Variable-sized solids or solutions/biologically inhibiting/water soluble air pollutants a. carbon monoxide b. sulfides, sulfates c. nitrites d. ozone antifreeze compounds (ethylene glycol) roadway hydrocarbons E. Variable-sized^iologically inhibiting/water insoluble 1. vehicular and roadway hydrocarbons a. oils b. grease c. tefraethyl lead and decomposition products Local Storm Water Pollution Prevention Plan V- Post Construction Quality Management (cont'd) 2. water-insoluble air pollutants (hydrocarbons) 3. pesticide/herbicide carriers F. Variable-sized solids or solutions/biologically toxic 1. common pesticides, herbicides, rodenticides a. malathion b. copper c. arsenic d. phenol e. 2,4 D f pyrethrins g. organo-mercury compounds h. others G. Variable-sized cultxu-e media^iologically active/water suspendable 1. animal excretions 2. dead animals 3. vegetation-biological nutrient soiu-ce 4. food wastes-biological nutrient source 5. soil-biological nutrient source 6. paper, wood, plastic, frash, waste, etc. Best Management Practices (BMP) Additional BMP's may be required based on tenant occupancy and use. If so, an addendum may be required listing BMP's pursuant to "DAMP". Routine Structural BMPs (51) Filtration - Surface runoff shall be directed to landscaped areas wherever practicable and as recommended by the engineer of record. (52) Common Area Efficient Irrigation - Physical implementation of the landscape plan will be consistent with the City's Water Conservation criteria. A licensed landscape maintenance crew will work to mitigate the amount of runoff from the landscaped areas. Specially designed confroUers and heads that allow multiple start times will be installed to confrol the amount of irrigation runoff onto existing sidewalks and parking areas. Drip and irrigation bubbler heads will be used to limit excess irrigation. Local Storm Water Pollution Prevention Plan V- Post Construction Quality Management (cont'd) (S3) Common Area Runoff-Minimizing Landscape Design - Plants with similar water requirements will be grouped in order to maximize the efficiency of the irrigation system. This grouping will eliminate the need for excessive irrigation and consequently will limit the possibility of irrigation water runoff. The selection of omamental plants for landscaping will be based upon criteria such as drought tolerance, rate of growth, resistance to disease, and compatibility with indigenous soil. (S6) Trash Container (Dumpster) Areas - All drainage from the building and pavement is diverted away from the frash container area. The frash container has enclosure and a swing door that is only open during trash pick-up. The frash enclosiu-e is higher than the surrounding ground and drainage into the area is limited and does not allow pollutant to runoff into the drainage system. The frash enclosure has a frash receptacle inside. (S13) Catch Basin Stenciling - "NO DUMPING - DRAINS TO OCEAN" will be stenciled on the catch basins by the sfreet confractor to alert the public to the destination of pollutants discharged into storm water. Stencils shall be placed per the City's standards. Appropriate Non-Structural BMPS (NI) Education for Property Owners and Occupants - Educational envfronmental awareness materials will be made available by Army Navy Academy or future property owner/tenant to all employees. These educational materials will address many topics: chemical use and disposal, trash confrol and disposal, and the elimination of storm drain discharge during site maintenance. Important phone numbers for additional information on water quality and pollution management will be given. Specifically, the educational material will include the following: • Retail/commercial building and vehicle-related commercial maintenance guidelines, including information on broom sweeping and vacuimiing, non-toxic or biodegradable products, collection programs, proper disposal of cleaning materials, and recycUng. • Landscape maintenance guidelines, including information on the proper use of pesticides, herbicides and fertilizers [to conform to the City's Management Guidelines for use of Fertilizers and Pesticides (MGFP)], collection and disposal of leaves and cuttings, and collection and disposal of animal wastes. In addition, guidelines will emphasize Local Storm Water Pollution Prevention Plan V- Post Construction Quality Management (cont'd) that use of a hose draining to gutters, catch basins and/or storm drains is not allowed when cleaning. (N2) Activity Restrictions - Army Navy Academy or future property owner/tenant will prepare guidelines and restiictions for future implementation and maintenance of all BMPs specified herein. Specific restiictions will include, but are not limited to, the following: • No Hosing of Paved Areas - Parking area surfaces and driveways will not be cleaned by "hosing down," but will instead be swept clean or vacuumed, with collected waste disposed of in a covered container. Oil stains will not be cleaned via an acid wash of the driveway. Instead, oil stains and leaks will be cleaned using rags or absorbents, then swept using granular absorbent material, and finally mopped. Mop water shall be disposed of into a sanitary sewer facility. • Trash - No rubbish, frash, garbage or other waste material shall be kept on-site or on any public sfreet abutting the properties, except in sanitary containers located in appropriate areas (frash containers). • Drainage - There shall be no interference with or alteration of the estabUshed drainage pattem on the site unless an adequate alternative provision is made for proper drainage with the prior written approval of the City. • Outside Storage - Storage of materials will not be allowed outside the main buildings unless authorized by the governing agencies. A revised WQMP will be issued in this event detailing the BMPs associated with outdoor storage. (N3) Common Area Landscape Management - Army Navy Academy or future property owner/tenant will bear the responsibihty for permanent vegetative cover as needed to stabilize the soil, and to be consistent with tiie City Water Conservation Resolution, and to follow the City's Management Guidelines for the Use of Fertilizers and Pesticides (MGFP). (N4) BMP Maintenance - Army Navy Academy or future property owner/tenant or future property owner will be responsible for inspection and maintenance of all BMPs described in this WQMP. The building owner will maintain erosion confrol devices on the site imtil adequate vegetation coverage is achieved. The site shall be inspected concurrent with routine groimds and landscaping maintenance. This includes inspection of all storm drain inlets to ensure their proper functioning. Local Storm Water Pollution Prevention Plan V- Post Construction Quality Management (cont'd) Following each major storm event, all stiiictural BMPs will be inspected to determine thefr effectiveness and need for repair. Some will require periodic removal of accumulated sediments. Any device damaged by a storm or foimd to be functioning poorly will be repaired or replaced immediately. (N5) Title 22 CCR Compliance - Army Navy Academy or future property owner/tenant shall be responsible for the compUance with any and all statutes of the Califomia Health and safety Code as it applies to the storage, use, and discarding of hazardous materials. Furthermore, the local Fire Authority shall be notified of any hazardous materials being stored on the site, and any spills of hazardous materials. (N7) Spill Contingency Plan - Army Navy Academy or future property owner/tenant shall prepare a spill contingency plan, if needed, for use by staff. The spill contingency plan shall, at a minimum, address the storage of cleanup materials, notification of responsible agencies in the event of a spill, the proper disposal of cleanup materials, and documentation of the spill. (NIO) Uniform Fire Code Implementation - The developer shall adhere to the recommendations of the City Fire Department in respect to compliance with Article 80 of the Uniform Fire Code, if required. (Nil) Common Area Litter Control - Army Navy Academy or fiiture property owner/tenant will implement frash management and litter confrol procedures to reduce pollution of drainage water. This may be achieved through contracting with a landscape maintenance firm to provide this service during regularly scheduled maintenance, which will include litter pafrol and emptying of frash receptacles in common areas. (N12) Employee Training - Army Navy Academy or future property owner/tenant shall prepare educational material regarding cleaning, maintenance, refinishing/painting, and both routine and emergency repairs of the landscape, hardscape, and parking areas. This material will address those products and methods to be used (and not to be used) for cleaning, maintenance, refinishing/repainting, and repair, storage of equipment and supplies, cleaning of equipment and reusable supplies, and collection and disposal of wastes and no longer usable supplies. Army Navy Academy shall prepare literature for the fraining of all staff in the proper Local Storm Water Pollution Prevention Plan V- Post Construction Quality Management (cont'd) use, storage and cleanup of all materials used by staff. Adequate training shall be given to the staff members. (N13) Housekeeping of Loading Docks - Army Navy Academy or fiiture property owner/tenant shall prepare educational material regarding cleaning of the loading dock area. This material will address those products and metiiods to be used (and not to be used) for cleaning the loading dock area and collection and disposal of wastes generated from this area. (N14) Common Area Trench Drain Inspection - Army Navy Academy or future property owner/tenant shall ensure that the gutter drains and storm drains are inspected periodically and cleaned no later than October 15 of each year. All wastes must be collected and disposed of in the common solid waste facilities of the site (hosing down or afr blowing are prohibited methods of cleaning, as is any use of detergents, soaps, acids, or lyes). (N15) Street Sweeping Private Streets and Parkmg Lots - Army Navy Academy or future property owner/tenant shall will ensure that access drive and parking areas will be swept clean prior to the storm season (no later than October 15), and all other hardscape witii adjoining landscape maintenance. Hosing or air blowing is not deemed acceptable methods. VI- Inspection and Maintenance Responsibility Army Navy Academy or future property owner/tenant will be responsible for inspection and maintenance of all BMPs described in this WQMP.
