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.
