All non-stormwater discharges associated with industrial and commercial activities that discharge into the city's municipal separate storm sewer system are prohibited, except as permitted by an individual user's NPDES permit, a NOI or section
19.20.090.
(Code 1980, § 19.20.180; Ord. No. 740, § 1, 2005)
A. All
businesses who own or operate facilities described in 40 CFR 122.26(b)(14)(i)—(xi)
are required to obtain coverage under the state's general industrial
permit at least 14 days prior to the commencement of activities that
may involve discharges to the MS4. All listed businesses are required
to submit a completed notice of intent (NOI) form, site map and application
fee to the state water resources control board (SWRCB). Such businesses
shall prepare a stormwater pollution prevention plan (SWPPP), retain
a copy of the SWPPP on site and comply with all the requirements of
the general industrial permit. (Copies of the NOI form are available
from the city's engineer.)
B. The
city requires that all businesses that have filed an NOI for coverage
under the state's general industrial permit and have received a waste
discharge identification number (WDID) from the state water resources
control board, either mail, FAX or hand deliver a copy of the WDID
letter from the state to the city engineer as proof of filing.
(Code 1980, § 19.20.190; Ord. No. 740, § 1, 2005; Ord. No. 870 (Recodification), 2014)
A. To
the extent permissible under state and federal law, businesses which
own or operate facilities described in 40 CFR 122.26(b)(14)(xi) may
prepare a notice of non-applicability in lieu of an NOI if they are
able to certify on the form provided by the state water resources
control board that there is no manufacturing process, material, equipment
or product storage outside in an area that is exposed to stormwater
runoff. The notice of non-applicability must document all of the following:
1. All
prohibited non-stormwater discharges have been eliminated or otherwise
permitted;
2. All
significant materials related to industrial activity (including waste
materials) are not exposed to stormwater or authorized non-stormwater
discharges;
3. All
industrial activities and industrial equipment are not exposed to
stormwater or authorized nonstormwater discharges; and
4. There
is no exposure of stormwater to significant materials associated with
industrial activity through other direct or indirect pathways such
as from industrial activities that generate dust and particulates.
B. Businesses
in this category are required to submit the notice of non-applicability
to the local or the regional board and are required to maintain the
above documentation on site at all times. They are also required to
re-evaluate and re-certify once a year that the conditions above are
continuously met. Copies of the notice of non-applicability form are
available from the city engineer.
(Code 1980, § 19.20.200; Ord. No. 740, § 1, 2005; Ord. No. 870 (Recodification), 2014)
All businesses, regardless of permit status, shall implement
all applicable BMPs, as listed in the California Storm Water Best
Management Practice Handbooks or the current county municipal stormwater
management program, to reduce pollutants in stormwater runoff and
reduce non-stormwater discharges to the MS4 to the maximum extent
practicable. All structural controls and BMPs shall also be maintained
to effectively prevent pollutants from contacting stormwater or remove
pollutants from stormwater runoff to the maximum extent practicable.
Maintenance records for structural BMPs and treatment devices, including
waste hauling receipts, shall be kept for a period of five years and
made available to the city's inspector upon request.
A. If
structural or treatment controls or BMPs are not functioning as designed
or are not effective in reducing stormwater pollutants or non-stormwater
discharges to the maximum extent practicable, the city will require
that the control device or BMP be repaired, rebuilt or replaced.
B. Storage
of materials, machinery and equipment. No person shall place machinery
or equipment that is to be repaired or maintained in areas susceptible
to or exposed to stormwater, in a manner that leaks, spills and other
maintenance-related pollutants are discharged to the municipal separate
storm sewer system.
C. Food
wastes. Food wastes generated by nonresidential food service and food
distribution sources shall be properly disposed of and in a manner
so such wastes are not discharged to the MS4.
D. Best
management practices. Best management practices shall be used in areas
exposed to stormwater for the removal and lawful disposal of all fuels,
chemicals, fuel and chemical wastes, animal wastes, garbage, batteries
or other materials which have potential adverse impacts on water quality.
(Code 1980, § 19.20.210; Ord. No. 740, § 1, 2005; Ord. No. 870 (Recodification), 2014)
