Current through Register Vol. 51, page 10, July 15, 2024
In addition to the information required by §
									74:52:02:08, existing
	 manufacturing, commercial, mining, and silvicultural dischargers applying for
	 SWD permits must provide the following information to the secretary, using
	 application forms provided by the secretary:
(1) The location of the outfalls, including
  the latitude and longitude to the nearest 15 seconds and the name of the
  receiving water;
(2) A line drawing
  of the water flow through the facility with a water balance, showing operations
  contributing wastewater to the effluent and treatment units. Similar processes,
  operations, or production areas may be indicated as a single unit, labeled to
  correspond to the more detailed identification under subdivision (3) of this
  section. The water balance must show approximate average flows at intake and
  discharge points and between units, including treatment units. If a water
  balance cannot be determined, the applicant may provide a pictorial description
  of the nature and amount of any sources of water and any collection and
  treatment measures;
(3) A narrative
  identification of each type of process, operation, or production area which
  contributes wastewater to the effluent for each outfall, including process
  wastewater, cooling water, and storm water runoff; the average flow which each
  process contributes; and a description of the treatment the wastewater
  receives, including the ultimate disposal of any solid or fluid wastes other
  than by discharge. For a privately owned treatment works, this information must
  include the identity of each user of the treatment works. The average flow of
  point sources composed of storm water may be estimated. The basis for the
  rainfall event and the method of estimation must be indicated;
(4) If any of the discharges described in
  subdivision (3) of this section are intermittent or seasonal, a description of
  the frequency, duration, and flow rate of each discharge occurrence, except for
  storm water runoff, spillage, or leaks;
(5) If an EPA effluent guideline incorporated
  by reference in §
									74:52:10:01 applies to the
  applicant and is expressed in terms of production or other measure of
  operation, a reasonable measure of the applicant's actual production reported
  in the units used in the applicable effluent guideline. The reported measure
  must reflect the actual production of the facility as required by §
									74:52:03:15;
(6) If the applicant is subject to any
  present requirements or compliance schedules for construction, upgrading, or
  operation of waste treatment equipment, an identification of the abatement
  requirement, a description of the abatement project, and a listing of the
  required and projected final compliance dates;
(7) When quantitative data for a pollutant is
  required in this subdivision, the applicant must collect a sample of effluent
  as set forth in 40 C.F.R.
  122.21 (g)(7) (July 24,
  1992) and analyze it for the pollutant in accordance with analytical methods
  approved under 40 C.F.R. Part 136 (July 1, 1996). The secretary may allow the
  applicant to test only one outfall and report that the quantitative data also
  applies to the substantially identical outfalls. The requirements in
  subsections (b) and (c) of this subdivision that require that an applicant
  provide quantitative data for certain pollutants known or believed to be
  present do not apply to pollutants present in a discharge solely as the result
  of their presence in intake water; however, an applicant must report such
  pollutants as present. Grab samples must be used for pH, temperature, cyanide,
  total phenols, residual chlorine, oil and grease, and fecal coliform. For all
  other pollutants, 24-hour composite samples must be used. However, a minimum of
  one grab sample may be taken for effluents from holding ponds or other
  impoundments with a retention period greater than 24 hours and a minimum of one
  to four grab samples may be taken for storm water discharges depending on the
  duration of the discharge. One grab sample must be taken in the first hour or
  less of discharge with one additional grab sample taken in each succeeding hour
  of discharge up to a minimum of four grab samples for discharges lasting four
  or more hours. In addition, the secretary may waive composite sampling for any
  outfall for which the applicant demonstrates that the use of an automatic
  sampler is not feasible and that the minimum of four grab samples will be a
  representative sample of the effluent being discharged. An applicant is
  expected to know or have reason to believe that a pollutant is present in an
  effluent based on an evaluation of the expected use, production, or storage of
  the pollutant or on any previous analyses for the pollutant. Applicants must
  report the following:
(a) Quantitative data
  for each outfall for the following pollutants:
(i) Biochemical oxygen demand
  (BOD);
(ii)Chemical oxygen demand
  (COD);
(iii) Total organic carbon
  (TOC);
(iv) Total suspended solids
  (TSS);
(v) Ammonia (as
  N);
(vi) Temperature (both winter
  and summer); and
(vii) pH.
The secretary may waive the reporting requirements for one or more of
	 the pollutants listed in this subsection if the applicant has demonstrated that
	 the waiver is appropriate because information adequate to support issuance of a
	 permit can be obtained with less stringent requirements;
