Many everyday activities at industrial facilities have the potential to pollute stormwater runoff. Since stormwater is not treated after it enters the storm sewer, it is very important to make sure that best management practices are in place to protect stormwater quality. Many industries are required to obtain a state permit to discharge stormwater from their facility. The Texas Commission on Environmental Quality (TCEQ) issues and enforces these permits. Additionally, local municipalities, such as the City of Houston and Harris County may have programs that enforce the TCEQ's industrial stormwater regulations, as well as their own stormwater regulations.

City of Houston Ordinances

The Stormwater Quality Enforcement Group (SWQE) of Public Works & Engineering Department Right of Way Maintenance Division inspects industrial and commercial facilities for compliance. Each of the facilities are inspected at least once every five years. Inspectors may inspect or review records, reports, data, plans, or other documents related to compliance with stormwater issues. In addition, an on-site evaluation ensures the facilities are not contributing illegal pollutants into the MS4.

With the adoption of the city ordinance in 2001, the SWQE group has the authority to issue citations and refer cases for state and federal investigations on those facilities that are not in compliance. Fines for citation range from $250 to $2,000 per day for each offense. SWQE offers assistance to those that are not familiar with the rules and regulations pertaining to stormwater quality. SWEQ works closely with federal, state, county agencies as well as other city departments.

Harris County Regulations

Harris County developed regulations that address industrial stormwater runoff.   Harris County Pollution Control Services Department enforces those regulations in unincorporated areas in Harris County. In general, these regulations parallel state requirements, but there are some important differences. First, facilities in the unincorporated area of Harris County that have a reportable spill are required to notify Harris County Pollution Control Services Department, in addition to other agencies it may be required to notify under state and federal regulations. Secondly, certain types of facilities whose stormwater runoff exceeds a benchmark or effluent limitation must notify Harris County Pollution Control Services Department within 30 days of the exceedance. There are several other differences; please be sure to review the Harris County Regulations, Part D, to ensure compliance.
