§ 34-853. Storm water pollution prevention plan requirements.

(1)

SWP3 Components. Each facility requiring a MSGP Permit shall develop and implement a Storm Water Pollution Prevention Plan (SWP3) prior to submitting a Notice of Intent to the TCEQ for MSGP permit coverage. The SWP3 must be maintained onsite or made readily available for review by SAWS upon request. The SWP3 shall include all elements identified in the MSGP language and continuously meet the criteria including any SWP3 updates and Best Management Practices (BMPs) maintenance as necessary to control discharge of pollutants. The SWP3 shall be developed to identify actual and potential sources of pollution that may reasonably be expected to affect the quality of storm water discharges from the facility. The SWP3 shall establish BMPs and any necessary structural control necessary to reduce or eliminate pollutants from the facility's storm water discharge. The SWP3 shall describe how such practices are appropriate for the facility and how each will effectively prevent or lessen pollution.

(2)

Sampling criteria. Each regulated facility shall take the appropriate samples at the frequency prescribed in the current MSGP. These storm water samples include but are not limited to: effluent limitations for hazardous metals, benchmark sampling and any sector specific sampling required under the MSGP.

(3)

Industrial and/or commercial facilities determined to potentially contribute pollutant loading to the MS4 may be required to perform additional monitoring as outlined by the TCEQ Municipal TPDES Permit to validate improvements to the BMPs and changes in the SWP3. This additional sampling can include, but is not limited to:

•

Any pollutant limited in an existing TPDES permit for the facility

•

Oil and Grease (O/G)

•

Chemical Oxygen Demand (COD)

•

pH

•

Biochemical Oxygen Demand (BOD5)

•

Total Suspended Solids (TSS)

•

Phosphorus (P)

•

Total Kjeldahl Nitrogen (TKN)

•

Nitrate plus Nitrite Nitrogen

•

Ammonia-nitrogen

•

Temperature

•

Total Organic Carbon (TOC)

•

E. Coli and Fecal Coliform

(4)

The SWP3 and monitoring data must be submitted to SAWS upon request.
