§ 15.01.015 REDUCTION OF POLLUTANTS IN STORMWATER.
   (A)   It is a violation of the chapter to throw, deposit, leave, maintain, keep, or permit to be thrown, deposited, placed, left or maintained, any pollutant in or upon any street, alley, sidewalk, storm drain, inlet, catch basin, conduit or other drainage structures, business place, or upon any public or private plot of land in the city. The only exception being where such pollutant is temporarily placed in an appropriate container with a spill containment system for later collection and removal. It is a violation of this ordinance to cause or permit any dumpster, solid waste bin, or similar container to leak such that any pollutant is discharged into any street, alley, sidewalk, storm drain, inlet, catch basin, conduit or other drainage structures, business place, or upon any public or private plot of land in the city.
   (B)   (1)   Any person performing construction work in the city shall comply with the provisions of this chapter, and shall control stormwater runoff so as to prevent any likelihood of adversely affecting human health or the environment. Director of Public Works shall identify the BMP’s that may be implemented to prevent such deterioration and shall identify the manner of implementation. Documentation on the effectiveness of BMP’s implemented to reduce the discharge of pollutants to the MS4 shall be required when requested by the Director of Public Works.
      (2)   Any person performing construction work in the city shall be regulated by the State Water Resources Control Board in a manner pursuant to and consistent with applicable requirements contained in the General Permit No. CAS000002, State Water Resources Control Board Order Number 2009-0009-DWQ. The city may notify the State Board of any person performing construction work that has a non-compliant construction site per the General Permit.
   (C)   New development or redevelopment projects shall control stormwater runoff so as to prevent any deterioration of water quality that would impair subsequent or competing uses of the water. The Director of Public Works shall identify the BMP’s that may be implemented to prevent such deterioration and shall identify the manner of implementation. Documentation on the effectiveness of BMP’s implemented to reduce the discharge of pollutants to the MS4 shall be required when requested by the Director of Public Works.
      The BMPs may include, but are not limited to, the following and may, among other things, require new developments or redevelopments to do any of the following:
      (1)   Increase permeable areas by leaving highly porous soil and low lying areas undisturbed; by incorporating landscaping, green roofs and open space into the project design; by using porous materials for or near driveways, drive aisles, parking stalls and low volume roads and walkways; and by incorporating detention ponds and infiltration pits into the project design.
      (2)   Direct runoff to permeable areas by orienting it away from impermeable areas to swales, berms, green strip filters, gravel beds, rain gardens, pervious pavement or other approved green infrastructure and French drains; by installing rain-gutters oriented towards permeable areas; by modifying the grade of the property to divert flow to permeable areas and minimize the amount of stormwater runoff leaving the property; and by designing curbs, berms or other structures such that they do not isolate permeable or landscaped areas.
      (3)   Maximize stormwater storage for reuse by using retention structures, subsurface areas, cisterns, or other structures to store stormwater runoff for reuse or slow release.
      (4)   Rain gardens may be proposed in-lieu of a water quality basin when applicable and approved by the city engineer.
   (D)   (1)   Existing development shall control stormwater runoff so as to prevent any deterioration of water quality that would impair subsequent or competing use of the water.
      (2)   The Director of Public Works shall identify the BMP’s that may be implemented to prevent such deterioration and shall identify the manner of implementation.
   (E)   Any person or entity that owns or operates a commercial and/or industrial facility(s) shall comply with the provisions of this chapter. All such facilities shall be subject to a regular program of inspection as required by this chapter, Riverside County Ordinance Nos. 457 and 857,any NPDES permit issued by the State Water Resource Control Board, Santa Ana Regional Water Quality Control Board, Cal. Water Code §§ 13000 et seq. (Porter-Cologne Water Quality Control Act), Title 33 U.S.C. §§ 1251 et seq. (Clean Water Act), any applicable state or federal regulations promulgated thereto, and any related administrative orders or permits issued in connection therewith.
