Current through Register Vol. 48, No. 6, June 28, 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 section 403(6)(a)(4)(6)(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 paragraph (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. 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 waste stream formula of section 403.6(f)(f). (See
				paragraph (b)(5)(iv) of this section.)
The Control Authority may allow for verifiable estimates of
				  these flows where justified by cost or feasibility considerations.
(5) Measurement of
				pollutants.
(i) The user shall identify the
				Pretreatment Standards applicable to each regulated process;
(ii) 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;
(iii) The User shall take
				a minimum of one representative sample to compile that data necessary to comply
				with the requirements of this paragraph.
(iv) 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
				waste stream formula of section 403.6(f)(f), in order to evaluate compliance
				with the Pretreatment Standards. Where an alternate concentration or mass limit
				has been calculated in accordance with section 403.6(f)(f) this adjusted limit
				along with supporting data shall be submitted to the Control
				Authority;
(v) Sampling and
				analysis shall be performed in accordance with the techniques prescribed in 40
				CFR Part 136 and amendments thereto. Where 40 CFR Part 136 does not contain
				sampling or analytical techniques for the pollutant in question, or where the
				Administrator or Department determines that the Part 136 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 or
				Department.
(vi) The Control
				authority may allow the submission of a baseline report which utilizes only
				historical data so long as the data provides information sufficient to
				determine the need for industrial pretreatment measures;
(vii) 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 paragraph
				(l) of this section ) and certified by a qualified professional, indicating
				whether Pretreatment Standards are being met on a consistent basis, and, if
				not, whether additional operation and maintenance (O & M) and/or additional
				Pretreatment is required for the Industrial User to meet the Pretreatment
				Standards and Requirements; and
(7)
				Compliance schedule. If additional pretreatment and/or O & 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 & M. The
				completion date in this schedule shall not be later than the compliance date
				established for the applicable Pretreatment Standard.
(i) Where the Industrial User's categorical
				Pretreatment Standard has been modified by the combined waste stream formula
				(section 403.6(f)(f)), and/or a Fundamentally Different Factors variance
				(section 403.13) at the time the User submits the report required by paragraph
				(b) of this section, the information required by paragraphs (b)(6) and (7) of
				this section shall pertain to the modified limits.
(ii) If the categorical Pretreatment Standard
				is modified by a removal allowance (section 403.7), the combined waste stream
				formula (section 403.6(f)(f)), and/or a Fundamentally Different Factors
				variance (section 403.13) at the time the User submits the report required by
				paragraph (b) of this section, the information required by paragraphs (b)(6)
				and (7) of this section shall be submitted by the Industrial User to the
				Control Authority within 60 days after the modified limit is
				approved.
