Texas Administrative Code › Title 30 - ENVIRONMENTAL QUALITY › Part 1 - TEXAS COMMISSION ON ENVIRONMENTAL QUALITY › Chapter 217 - DESIGN CRITERIA FOR DOMESTIC WASTEWATER SYSTEMS › Subchapter B - TREATMENT FACILITY DESIGN REQUIREMENTS › Section 217.34 - Organic Loadings and Flows for Existing Wastewater Treatment Facilities, Re-Ratings, and Alterations

Current through Reg. 49, No. 28; July 12, 2024
An owner who proposes to alter, or re-rate an existing
					 wastewater treatment facility, or to obtain approval for an existing wastewater
					 treatment facility after that wastewater treatment facility's permit has
					 expired, is required to use the wastewater treatment facility's current
					 operating data for flow and organic loading (biochemical oxygen demand or
					 carbonaceous biochemical oxygen demand, total suspended solids, and ammonia
					 nitrogen, as required by the permit) as the design basis. The compiled data
					 must meet the criteria outlined in paragraphs (1) and (2) of this
					 section.
(1) Flows.
(A) When an existing wastewater treatment
				  facility is to be re-rated or altered, the wastewater treatment facility's data
				  for the last five years must be used to determine the annual average flow, the
				  maximum monthly average flow, the peak flow, the ratio of maximum monthly
				  average flow to annual average flow, and the ratio of the peak flow to the
				  annual average flow. All flow data for these analyses must be collected by a
				  totalizing meter. If the wastewater treatment facility is less than five years
				  old, all existing data must be used. All calculations and assumptions must be
				  included in the engineering report.
(B) An analysis of the peak flow must be
				  based on a frequency distribution analysis using flow charts for each
				  individual day.
(C) The projected
				  peak flow must be the result of collection system monitoring or modeling based
				  on a two-year, 24-hour storm event for the service area.
(D) For a wastewater treatment facility that
				  will not be affected by future growth, the design flow for a re-rating or
				  alteration must be calculated using the wastewater treatment facility's average
				  flow plus one standard deviation.
(E) For a wastewater treatment facility that
				  will be affected by future growth, the design flow for a re-rating or
				  alteration must be based on future flow, calculated using anticipated changes
				  from the existing flow. The design analysis may use a linear regression or
				  other appropriate statistical method for predicting the design flow when
				  significant data exists.
Texas Administrative Code › Title 30 - ENVIRONMENTAL QUALITY › Part 1 - TEXAS COMMISSION ON ENVIRONMENTAL QUALITY › Chapter 217 - DESIGN CRITERIA FOR DOMESTIC WASTEWATER SYSTEMS › Subchapter B - TREATMENT FACILITY DESIGN REQUIREMENTS › Section 217.35 - One Hundred-Year Flood Plain Requirements

Current through Reg. 49, No. 28; July 12, 2024
(a) If a 100-year flood plain is located
				  within 1,000 feet of the site of a wastewater treatment facility, the 100-year
				  flood plain must be shown on the site plan. A flood plain determination must be
				  based on a superimposition of the 100-year flood elevation on the most accurate
				  available topography and elevation data for the site.
(1) A 100-year flood plain must be based on
				  the Federal Emergency Management Agency (FEMA) Flood Insurance Study in effect
				  at the time the plans and specifications are submitted to the executive
				  director. FEMA maps are prima facie evidence of flood plain
				  locations.
(2) An appropriate flood
				  insurance rate map or Flood Insurance Study profile, adjusted to the site's
				  vertical data, may be used to determine flood elevations.
(3) If a site is adjacent to a FEMA 100-year
				  flood delineation, but has no flood elevation published, a 100-year flood
				  elevation may be determined by overlaying the effective FEMA delineation over a
				  United States Geological Survey Quadrangle Map and interpolating a flood
				  elevation.
(4) If FEMA flood plain
				  information is not available, the engineering report shall include a 100-year
				  flood elevation based on the best information available.

				  Supervisory Control and Data Acquisition (SCADA) system, or a telemetering
				  system connected to a continuously monitored location. Audiovisual alarms are
				  not required if the SCADA system notifies the operator about communication
				  loss, in addition to all other alarm conditions.
(c) An alarm system must self-activate if:
(1) the power supply is
				  interrupted;
(2) a pump fails;
				  or
(3) a high water level alarm is
				  triggered.
