Current through June 24, 2024
(1) Within 180 days
				  after the effective date of a categorical pretreatment standard as published in
				  the federal register, or 180 days after the final decision in a request for
				  category determination under s.
				  NR
				  211.33, whichever is later, industrial users subject
				  to that standard which are not new sources and which are currently discharging
				  or scheduled to discharge into a POTW shall submit to the control authority a
				  report containing the information listed in pars. (a) to (g), except when
				  reports containing this information have already been submitted to the control
				  authority for other purposes. At least 90 days before the commencement of
				  discharge, new sources and sources that become industrial users subsequent to
				  the promulgation of an applicable categorical pretreatment standard shall
				  submit a report to the control authority which at a minimum contains the
				  information listed in pars. (a) to (e). New sources shall estimate the
				  information required by pars. (d) and (e). New sources shall also include in
				  this report information regarding the method of pretreatment that will be used
				  to meet the applicable pretreatment standards. The control authority may
				  require the industrial user to submit any additional information which the
				  control authority finds is necessary to determine the industrial user's ability
				  to meet the applicable pretreatment standards.
(a) The name, address, and location of the
				  industrial user and the name of the owner or operator.
(b) A list of any environmental control
				  permits held by or for the industrial user.
(c) The nature and average rate of production
				  and the standard industrial classification of the processes carried out by the
				  industrial user. This description shall include a schematic diagram which
				  indicates points of discharge to the POTW from the processes regulated by the
				  applicable categorical pretreatment standard.
(d) The measured average and maximum flows
				  from the industrial user to the POTW, in gallons per day, from regulated
				  process streams and other streams as necessary to allow use of the combined
				  wastestream formula of s.
				  NR 211.12.
				  When approved by the control authority based on considerations of cost or
				  accessibility, the average and maximum flow of the discharge may be estimated
				  by verifiable techniques.
(e) The
				  nature and concentration of pollutants in the discharge from each of the
				  industrial user's regulated processes and an identification of the applicable
				  categorical pretreatment standards and pretreatment requirements. The nature
				  and concentration of pollutants in each discharge shall be determined in
				  accordance with subds. 1. to 5. 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 standard to determine compliance.
1. Sampling and analysis shall be performed
				  to identify the concentration or mass of regulated pollutants in the discharge
				  from each regulated process, according to the requirements of the applicable
				  categorical pretreatment standard and the control authority. Both daily maximum
				  and average values shall be reported. Samples shall be representative of daily
				  operations. A minimum of 4 grab samples per day shall be used for pH, cyanide,
				  total phenols, oil and grease, sulfide and volatile organics. All other samples
				  shall be 24-hour flow proportional composites, unless time proportional or grab
				  sampling is authorized by the control authority. Where alternative sampling is
				  authorized by the control authority, the samples shall be representative of the
				  discharge and the decision to allow alternative methods shall be documented in
				  the industrial user's file. Multiple grab samples collected during a 24-hour
				  period may be composited prior to analysis provided appropriate protocols
				  specified in ch. NR 219, and in EPA and department guidance are followed.
				  Samples for cyanide, total phenols and sulfides may be composited in the
				  laboratory or in the field. Samples for volatile organics and oil and grease
				  may be composited in the laboratory. Other samples may be composited using
				  approved methodologies as authorized by the control authority.
2. The industrial user shall collect and
				  analyze a minimum of one representative sample to compile the data necessary
				  for this subsection. Sampling shall be performed during full facility
				  production when substances subject to regulation, including those in batch or
				  periodic discharges, are likely to be present in maximum concentrations or
				  quantities for the reporting period. The control authority may require more
				  frequent monitoring when necessary to assess compliance with the applicable
				  pretreatment standards and requirements. If an industrial user samples any
				  pollutant more frequently than required by the control authority and analyzes
				  these samples according to sub. (8), the results of this monitoring shall be
				  included in the report.
3. Samples
				  shall be taken at the discharge from the regulated process, or at the discharge
				  from pretreatment facilities provided that wastewaters that are not regulated
				  by the applicable categorical pretreatment standard are not mixed with the
				  regulated waste-stream prior to the sampling point. Where sampling according to
				  this provision is not feasible, the department may consider allowing
				  alternative means of sampling to be used to determine compliance with the
				  applicable categorical pretreatment standard at the point of discharge from the
				  regulated process. If streams which are not regulated by the applicable
				  categorical pretreatment standard are mixed with the regulated stream prior to
				  the sampling point, the industrial user shall measure the flows and
				  concentrations necessary to allow use of the combined wastestream formula of s.
				  NR 211.12
				  in order to evaluate compliance with the pretreatment standards. Where an
				  alternative concentration or mass limit has been calculated in accordance with
				  s.
				  NR 211.12
				  this adjusted limit along with the supporting data shall be submitted to the
				  control authority.
4.
				  Representative historical data may be used in the initial baseline report with
				  the approval of the control authority.
5. The report shall indicate the time, date,
				  and place of sampling, method of analysis, and shall certify that sampling and
				  analysis are representative of normal work cycles and expected pollutant
				  discharges to the POTW.
(f) A statement indicating whether the
				  applicable categorical pretreatment standards are being met on a consistent
				  basis and, if not, whether additional operation and maintenance, or additional
				  pretreatment, or both, is required in order for the industrial user to meet the
				  applicable categorical pretreatment standards. The statement shall be reviewed
				  by an authorized representative of the industrial user and certified by a
				  qualified professional.
(g) If
				  additional pretreatment or operation and maintenance is needed, the industrial
				  user shall submit the shortest schedule by which additional treatment or
				  operation and maintenance can be provided. The completion date resulting from
				  this schedule may not be later than the compliance date established for the
				  applicable categorical pretreatment standard. The schedule shall specify dates
				  for the commencement and completion of the major events necessary to provide
				  the additional pretreatment or operation and maintenance. The length of time
				  between any 2 dates may not exceed 9 months.
(h) Where the industrial user's discharge
				  limit has been modified by a fundamentally different factors variance (s.
				  NR
				  211.14 ), a removal credit (s.
				  NR
				  211.13 ), or the combined wastestream formula (s.
				  NR 211.12 )
				  at the time the report is submitted, the information required in pars. (f) and
				  (g) shall pertain to the modified limit. Revisions to the information submitted
				  under pars. (f) and (g) may be required by the department where the industrial
				  user's discharge limit is modified at a later date.
