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)

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
