Current through Register Vol. 50, No. 6, June 20, 2024
A. Reserved.
B. Reporting Requirements for Industrial
				  Users upon Effective Date of Categorical Pretreatment Standard-Baseline Report.
				  Within 180 days after the effective date of a categorical pretreatment
				  standard, or 180 days after the final administrative decision made upon a
				  category determination submission under LAC 33:IX.6111.A.4, whichever is later,
				  existing industrial users subject to such categorical pretreatment standards
				  and currently discharging to or scheduled to discharge to a POTW shall be
				  required to submit to the control authority a report which contains the
				  information listed in Paragraphs B.1-7 of this Section. At least 90 days prior
				  to commencement of discharge, new sources, and sources that become industrial
				  users subsequent to the promulgation of an applicable categorical standard,
				  shall be required to submit to the control authority a report which contains
				  the information listed in Paragraphs B.1-5 of this Section. New sources shall
				  also be required to include in this report information on the method of
				  pretreatment the source intends to use to meet applicable pretreatment
				  standards. New sources shall give estimates of the information requested in
				  Paragraphs B.4 and 5 of this Section.
1.
				  Identifying Information. The user shall submit the name and address of the
				  facility including the name of the operator and owners.
2. Permits. The user shall submit a list of
				  any environmental control permits held by or for the facility.
3. Description of Operations. The user shall
				  submit a brief description of the nature, average rate of production, and
				  standard industrial classification of the operation(s) carried out by such
				  industrial user. This description should include a schematic process diagram
				  which indicates points of discharge to the POTW from the regulated
				  processes.
4. Flow Measurement
a. The user shall submit information showing
				  the measured average daily and maximum daily flow, in gallons per day, to the
				  POTW from each of the following:
i. regulated
				  process streams; and
ii. other
				  streams as necessary to allow use of the combined wastestream formula of LAC
				  33:IX.6111.E. (see Subparagraph B.5.d of this Section.)
b. The control authority may allow for
				  verifiable estimates of these flows where justified by cost or feasibility
				  considerations.
5.
				  Measurement of Pollutants
a. The user shall
				  identify the pretreatment standards applicable to each regulated
				  process.
b. In addition, the user
				  shall submit the results of sampling and analysis identifying the nature and
				  concentration (or mass, where required by the standard or control authority) of
				  regulated pollutants in the discharge from each regulated process. Both daily
				  maximum and average concentration (or mass, where required) shall be reported.
				  The sample shall be representative of daily operations. In cases where the
				  standard requires compliance with a best management practice or pollution
				  prevention alternative, the user shall submit documentation as required by the
				  control authority or the applicable standards to determine compliance with the
				  standard.
c. The user shall take a
				  minimum of one representative sample to compile that data necessary to comply
				  with the requirements of this Paragraph.
d. Samples should be taken immediately
				  downstream from pretreatment facilities if such exist or immediately downstream
				  from the regulated process if no pretreatment exists. If other wastewaters are
				  mixed with the regulated wastewater prior to pretreatment the user should
				  measure the flows and concentrations necessary to allow use of the combined
				  wastestream formula of LAC 33:IX.6111.E, in order to evaluate compliance with
				  the pretreatment standards. Where an alternate concentration or mass limit has
				  been calculated in accordance with LAC 33:IX.6111.E, this adjusted limit along
				  with supporting data shall be submitted to the control authority.
e. Sampling and analysis shall be performed
				  in accordance with the techniques prescribed in         40 CFR Part 136         (see LAC
				  33:IX.4901) and amendments thereto. Where 40 CFR Part 136 (see LAC 33:IX.4901)
				  does not contain sampling or analytical techniques for the pollutant in
				  question, or where the administrator determines that the 40 CFR Part 136 (see
				  LAC 33:IX.4901) sampling and analytical techniques are inappropriate for the
				  pollutant in question, sampling and analysis shall be performed by using
				  validated analytical methods or any other applicable sampling and analytical
				  procedures, including procedures suggested by the POTW or other parties,
				  approved by the administrator.
f.
				  The control authority may allow the submission of a baseline report that
				  utilizes only historical data so long as the data provides information
				  sufficient to determine the need for industrial pretreatment
				  measures.
g. The baseline report
				  shall indicate the time, date, and place of sampling, and methods of analysis,
				  and shall certify that such sampling and analysis is representative of normal
				  work cycles and expected pollutant discharges to the POTW.
6. Certification. A statement, reviewed by an
				  authorized representative of the industrial user (as defined in Subsection L of
				  this Section) and certified to by a qualified professional, indicating whether
				  pretreatment standards are being met on a consistent basis and, if not, whether
				  additional operation and maintenance (O and M) and/or additional pretreatment
				  is required for the industrial user to meet the pretreatment standards and
				  requirements.
7. Compliance
				  Schedule. If additional pretreatment and/or O and M will be required to meet
				  the pretreatment standards; the shortest schedule by which the industrial user
				  will provide such additional pretreatment and/or O and M. The completion date
				  in this schedule shall not be later than the compliance date established for
				  the applicable pretreatment standard.
a.
				  Where the industrial user's categorical pretreatment standard has been modified
				  by a removal allowance (LAC 33:IX.6113), the combined wastestream formula (LAC
				  33:IX.6111.E), and/or a fundamentally different factors variance (LAC
				  33:IX.6125) at the time the user submits the report required by Subsection B of
				  this Section, the information required by Paragraphs B.6 and 7 of this Section
				  shall pertain to the modified limits.
b. If the categorical pretreatment standard
				  is modified by a removal allowance (LAC 33:IX.6113), the combined wastestream
				  formula (LAC 33:IX.6111.E), and/or a fundamentally different factors variance
				  (LAC 33:IX.6125) after the user submits the report required by Subsection B of
				  this Section, any necessary amendments to the information requested by
				  Paragraphs B.6 and 7 of this Section shall be submitted by the user to the
				  control authority within 60 days after the modified limit is
				  approved.
