The National Urban Runoff Program reported to Congress in the 1980’s and identified storm water as a discharge likely causing water quality impairment. In 1987, Congress amended the Clean Water Act requiring the EPA to address storm water discharges. In 1996, the EPA issued the Industrial General Permit to Discharge Wastes For Storm Water From Industrial Facilities. On August 20, 2001, the TNRCC (TCEQ) issued the TPDES Multi-Sector Permit (TXR050000) to regulate storm water discharges from Industrial Facilities. That permit was set to expire on August 20, 2006. A new General Permit To Discharge Wastes from Industrial Facilities was issued by the TCEQ on August 14, 2006. The current Multi-Sector Permit expires on August 14, 2011.

The goal of the City of Amarillo’s industrial portion of the Storm Water Program is to provide for the safety and health of the citizens of Amarillo and the surrounding area, to provide for appropriate water quality in the MS4 and receiving waters, and to provide guidance to local businesses to operate in compliance with federal, state, and local storm water regulations.

The Standard Industrial Code (SIC) or North American Industry Classification System (NAICS) classification determines whether an industry qualifies to discharge under the Multi-Sector General Permit (TXR050000) or the Redi-Mix General Permit (TXG11000). By clicking here, SIC Codes, you can determine whether your industry is required to obtain authorization to discharge storm water under one of these permits.

If you must obtain authorization, you are required to develop a Storm Water Pollution Prevention Plan (SWP3), and submit a Notice of Intent (NOI) to the State and to the City of Amarillo. TPDES Worksheets are available to help you develop the plan by clicking on the appropriate topic here, SWP3 Worksheets or SWP3 Instructions. A SWP3 must be completed before submittal of a NOI. A NOI is required to be submitted, for a NEW industrial facility, at least 48 hours before a discharge of storm water associated with the industrial activity occurs. A NOI must be submitted 10 days before change of ownership of an EXISTING permitted facility, and the seller must submit a Notice of Termination (NOT), 10 days before change of ownership.

Your facility may qualify for a Conditional No Exposure Exclusion from permit requirements if there is no exposure of industrial materials or activities to precipitation or runoff. The Permit discusses eligibility requirements of the Conditional No Exposure Exclusion on Page 21, Part II, Section C.1.
