Section 327.32 - Reporting Requirements for Certain Accidental Discharges or Spills of Treated or Untreated Wastewater at Wastewater Treatment Facilities or Collection Systems(a) The following words and terms, when used in this section, shall have the following meanings, unless the context clearly indicates otherwise. (1) Collection system--Pipes, conduits, lift stations, force mains, and all other constructions, devices, and appurtenant appliances used to transport domestic wastewater to a wastewater treatment facility.(2) History of noncompliance--History of non-reporting or reoccurrences of accidental discharges or spills of treated or untreated wastewater.(3) Local government--An incorporated city, a county, a river authority, or a water district or authority acting under Article III, Section 52, or Article XVI, Section 59 of the Texas Constitution.(4) Wastewater treatment facility--All contiguous land and fixtures, structures, and appurtenances used for storing, processing, and treating wastewater. A wastewater treatment facility does not include the collection system located outside of the fenced area around a wastewater treatment facility.(b) Except as provided by subsection (c) of this section, all accidental discharges or spills of treated or untreated wastewater shall be reported within 24 hours of the occurrence. A written submission shall be provided to the executive director within five days of the occurrence. The written submission shall contain a description of the accidental discharge or spill and its cause; the potential danger to human health or safety, or the environment; the duration of the accidental discharge or spill, including exact dates and times; if the cause of the accidental discharge or spill has not been corrected, the time it is expected to continue; and steps taken or planned to reduce, eliminate, and prevent recurrence, and to mitigate its adverse effects.(c) The responsible person of a wastewater treatment facility or collection system that is owned or operated by a local government may report accidental discharges or spills of treated or untreated wastewater that do not endanger human health or safety or the environment to the executive director as a monthly summary if each individual accidental discharge or spill: (1) has a volume of 1,000 gallons or less;(2) is not associated with another simultaneous accidental discharge or spill of treated or untreated wastewater;(3) is controlled or removed before the accidental discharge or spill enters water in the state or adversely affects a public or private source of drinking water; and(4) is not otherwise subject to local regulatory control and reporting requirements.(d) The responsible person shall submit a monthly summary by the 20th day of the month for each accidental discharge or spill that occurred during the previous month. The summary must include, at a minimum, the: (1) location, volume and content of the accidental discharge or spill;(2) description of the accidental discharge or spill;(3) cause of the accidental discharge or spill;(4) dates and times of the accidental discharge or spill; and(5) steps taken to reduce, eliminate, and prevent recurrence of the accidental discharge or spill.(e) The responsible person must use one of the following methods for determining the volume of the discharge or spill. (1) Visual estimate. If the accidental discharge or spill is less than 55 gallons, using a standard five-gallon bucket for reference, estimate the number of buckets that the discharge or spill would fill then multiply by five to obtain the number of gallons discharged or spilled. If the accidental discharge or spill is larger than 55 gallons, using a standard 55 gallon barrel for reference, estimate the number of barrels that the discharge or spill would fill and then multiply by 55 to obtain the number of gallons discharged or spilled.(2) Measured volume. Identify the length, width, and depth of the contained accidental discharge or spill in feet and calculate the volume by multiplying length by width by depth by 7.5 (the conversion factor from cubic feet to gallons).(3) Duration and flow rate. Identify separate estimates for the duration and the flow rate of the accidental discharge or spill. The estimated volume is calculated by multiplying the duration (hours or days) by the flow rate (gallons/hour or gallons/day).(4) Other methods. The responsible person may use other volumetric calculation methodologies rather than those listed in paragraphs (1) - (3) of this subsection, so long as such methodologies include procedures to identify a duration, flow rate, depth, affected area, and total quantity of each spill (including, as appropriate, reference to estimation tools such as barrels, for example), and such methodology is consistent with standard and accepted industry practices. Such alternative methodologies must be identified in the responsible person's monthly report.(f) The responsible person must keep records of all accidental discharges or spills of treated or untreated wastewater reported under this section. The records must remain on-site for three years and be made immediately available to commission staff upon request.(g) The executive director may require more frequent reporting based on the responsible person's history of noncompliance.30 Tex.
