Green Stormwater Infrastructure (GSI) are stormwater control measures (SCMs) that capture, manage, and treat stormwater runoff by mimicking natural hydrologic and pollutant removal processes.
(f) No person shall introduce or cause to be introduced into the MS4 any harmful quantity of concrete, asphalt, sediment, silt, earth, soil, or other material associated with clearing, grading, excavation or other construction activities in excess of what could be retained on site or captured by employing sediment and erosion control measures to the maximum extent practicable.
(g) No person shall connect a line conveying sanitary sewage, domestic or industrial, to the MS4, or allow such a connection to continue.
(a) Applicability for industrial and construction activity.
(1) This section applies to all facilities and construction sites located within the city limits or otherwise subject to the regulatory authority of the City of Lubbock that have stormwater discharges associated with industrial activity or construction site activity.
(2) State of Texas regulations require that subject facilities apply for and obtain general permits for industrial facilities (TPDES TXR050000) and construction sites (TXR150000) that have been determined to contribute or have the potential to contribute substantial pollutant loads to the municipal stormwater drainage system or waters of the state. The general permits require that the permittee develop, implement, and maintain a stormwater pollution prevention plan (SWP3) and submit a notice of intent notifying the TCEQ and the municipal stormwater drainage system operator (City of Lubbock).
(3) The MS4 permit issued to the City of Lubbock by the TCEQ mandates that the City of Lubbock “Carry out all inspections, surveillance, and monitoring procedures necessary to determine compliance with permit conditions” (Part III (E)(6)) and implement a program that includes “Inspection of construction sites and enforcement of control measure requirements” (Part III (B)(9)(b)).
d) Review and modifications of best management practices (BMPs).
(1) Any person engaged in activities or operation, or owning facilities or property, which will or may result in pollutants entering the MS4 or waters of the United States by means of wind and/or precipitation, shall implement BMP’s to the MEP to prevent and reduce such pollutants. The owner or operator of a regulated facility shall provide reasonable protection from accidental discharge of prohibited materials or other wastes into the MS4 or waters of the United States. Practices implemented to prevent accidental discharge of prohibited materials or other wastes shall be provided and maintained at the owner or operator’s expense.
(2) The City of Lubbock will maintain a list of approved BMP’s within the City of Lubbock’s Drainage Criteria Manual. The stormwater engineer may request a demonstration of the effectiveness of implemented BMP’s.
(3) The stormwater engineer may require an operator of a regulated facility to modify its BMP’s if, in the best professional judgment of the stormwater engineer, the BMP’s do not provide effective protection from accidental discharge of prohibited materials or other wastes from entering into the municipal stormwater drainage system or waters of the United States.
(4) The deficiencies in a facilities BMP’s will be communicated in writing, and the stormwater engineer will provide the operator a reasonable amount of time, not to exceed sixty (60) days, to make the necessary changes in the BMP’s. Permit time requirements for controlling pollutants in runoff shall remain applicable.
