Louisiana Administrative Code › Title 33 - ENVIRONMENTAL QUALITY › Part IX - Water Quality › Subpart 2 - The Louisiana Pollutant Discharge Elimination System (LPDES) Program › Chapter 61 - General Pretreatment Regulations for Existing and New Sources of Pollution › Section IX-6115 - Pretreatment Program Requirements: Development and Implementation by POTW

Current through Register Vol. 50, No. 6, June 20, 2024
A. POTWs Required
				  to Develop a Pretreatment Program. Any POTW (or combination of POTWs operated
				  by the same authority) with a total design flow greater than 5 million gallons
				  per day (mgd) and receiving from industrial users pollutants which pass through
				  or interfere with the operation of the POTW or are otherwise subject to
				  pretreatment standards will be required to establish a POTW pretreatment
				  program unless the NPDES state exercises its option to assume local
				  responsibilities as provided for in LAC 33:IX.6119.E. The EPA regional
				  administrator or state administrative authority may require that a POTW with a
				  design flow of 5 mgd or less develop a POTW pretreatment program if he or she
				  finds that the nature or volume of the industrial influent, treatment process
				  upsets, violations of POTW effluent limitations, contamination of municipal
				  sludge, or other circumstances warrant in order to prevent interference with
				  the POTW or pass through.
B.
				  Deadline for Program Approval. A POTW which meets the criteria of Subsection A
				  of this Section must receive approval of a POTW pretreatment program no later
				  than three years after the reissuance or modification of its existing permit
				  but in no case later than July 1, 1983. POTWs whose permits are modified under
				  Section 301(h) of the Act shall have a pretreatment program within three years
				  as provided for in  40 CFR Part 125, Subpart G. POTWs identified after July 1,
				  1983 as being required to develop a POTW Pretreatment Program under Subsection
				  A of this Section shall develop and submit such a program for approval as soon
				  as possible, but in no case later than one year after written notification from
				  the approval authority of such identification. The POTW Pretreatment Program
				  shall meet the criteria set forth in Subsection F of this Section and shall be
				  administered by the POTW to ensure compliance by industrial users with
				  applicable pretreatment standards and requirements.
C. Incorporation of Approved Programs in
				  Permits. A POTW may develop an appropriate POTW pretreatment program any time
				  before the time limit set forth in Subsection B of this Section. The POTW's
				  LPDES permit will be reissued or modified by the NPDES state or EPA to
				  incorporate the approved program conditions as enforceable conditions of the
				  permit. The modification of a POTW's LPDES permit for the purposes of
				  incorporating a POTW pretreatment program approved in accordance with the
				  procedures in LAC 33:IX.6121 shall be deemed a minor permit modification
				  subject to the procedures in LAC 33:IX.2905.
D. Reserved.
E. Cause for Reissuance or Modification of
				  Permits. Under the authority of Section 402(b)(1)(C) of the Act, the approval
				  authority may modify, or alternatively, revoke and reissue a POTW's permit in
				  order to:
1. put the POTW on a compliance
				  schedule for the development of a POTW pretreatment program where the addition
				  of pollutants into a POTW by an industrial user or combination of industrial
				  users presents a substantial hazard to the functioning of the treatment works,
				  quality of the receiving waters, human health, or the environment;
2. coordinate the issuance of a Section 201
				  of the Act construction grant with the introduction into a permit of a
				  compliance schedule for POTW pretreatment program;
3. incorporate a modification of the permit
				  approved under Section 301(h) of the Act;
4. incorporate an approved POTW pretreatment
				  program in the POTW permit;
5.
				  incorporate a compliance schedule for the development of a POTW pretreatment
				  program in the POTW permit; or
6.
				  incorporate the removal credits (established under LAC 33:IX.6113) in the POTW
				  permit.
