Wyoming Administrative Code › Agency 020 - Environmental Quality, Dept. of › Sub-Agency 0011 - Water Quality › Chapter 2 - DISCHARGES, PERMIT REGS › Appendix C - Additional Requirements Applicable to New Manufacturing, Commercial, Mining and Silvicultural Discharges

Current through July 13, 2024
(a) New manufacturing, commercial, mining and silvicultural
				  dischargers applying for permits (except for new discharges of facilities
				  subject to the requirements of Appendix D of these regulations), shall provide
				  the following information, in addition to that described in Section
				  5(a) (v), to the administrator, using the application
				  form provided by the administrator.
(i) Discharge dates. The expected date of commencement of
				  discharge.
(ii) Flows, sources of pollution, and treatment
				  technologies.
(A) Expected treatment of wastewater. Description of the
				  treatment that the wastewater will receive, along with all operations
				  contributing wastewater to the effluent, average flow contributed by each
				  operation, and the ultimate disposal of any solid or liquid wastes not
				  discharges.
(B) Line drawing. A line drawing of the water flow through
				  the facility with a water balance as described in Appendix B (a) (i).
(C) Intermittent flows. If any of the expected discharges
				  will be intermittent or seasonal, a description of the frequency, duration and
				  maximum daily flow rate of each discharge occurrence (except for storm water
				  runoff, spillage, or leaks).
(iii) Production. If a new source performance standard
				  promulgated under Section 306 of the CWA or an effluent limitation guideline
				  applies to the applicant and is expressed in terms of production (or other
				  measure of operation), a reasonable measure of the applicant's expected actual
				  production reported in the units used in the applicable effluent guideline or
				  new source performance standard for each of the first three (3) years.
				  Alternative estimates may also be submitted if production is likely to
				  vary.
(iv) Effluent characteristics.
(A) Each applicant must report estimated daily maximum, daily
				  average, and source of information for each outfall for the following
				  pollutants or parameters.
(I) Biochemical Oxygen Demand
				  (BOD5),
(II) Chemical Oxygen Demand (COD),
(III) Total Suspended Solids (TSS),
(IV) Flow,
(V) Ammonia (as N),
(VI) Temperature (winter and summer),
(VII) pH, and
(VIII) Total Organic Carbon (TOC).
(B) The administrator may waive the reporting requirements
				  for any of the pollutants and parameters in Appendix C (a) (iv) (A) if the
				  applicant submits a request for such a waiver before or with the application
				  which demonstrates that information adequate to support issuance of the permit
				  can be obtained through less stringent reporting requirements.
(C) Each applicant must report estimated daily maximum, daily
				  average, and source of information for each outfall for all pollutants in Table
				  IV of Appendix D 40 CFR Part 122 (certain conventional and no n-conventional
				  pollutants) if the applicant knows or has reason to believe the pollutants will
				  be present or if the pollutants are limited by an effluent limitation guideline
				  or new source performance standard either directly or indirectly through
				  limitations on an indicator pollutant.
(D) Each applicant must report estimated daily maximum, daily
				  average and source of information for the following pollutants if they know or
				  have reason to believe that the pollutant will be present in the discharges
				  from any outfall:
(I) The pollutants listed in Table III of Appendix D (the
				  toxic metals, in the discharge from any outfall: Total cyanide, and total
				  phenols) of 40 CFR Part 122;
(II) The organic toxic pollutants in Table II of Appendix D
				  (except bis (chloromethyl) ether, dichlorofluoromethane and
				  trichlorofluoromethane) of 40 CFR Part 122. This requirement is waived for
				  applicants qualifying for the small business exemption as specified in Appendix
				  B (a) (xi).
(E) The applicant is required to report that 2,3,7,8
				  Tetrachlorodibenzo-P-Dioxin (TCDD) may be discharged if he uses or manufactures
				  one of the following compounds, or if he knows or has reason to believe that
				  TCDD will or may be present in an effluent:
(I) 2,4,5-trichlorophenoxy acetic acid (2,4,5-T) (CAS
				  #93-76-5 );
(II) 2-(2,4,5-trichlorophenoxy) propanoic acid (Silvex,
				  2,4,5-TP) (CAS #93-72-1 );
(III) 2-(2,4,5-trichlorophenoxy) ethyl 2,2-dichloropropionate
				  (Erbon) (CAS #136-25-4 );
(IV) 0,0-dimethyl 0-(2,4,5-trichlorophenyl) phosphorothioate
				  (Ronnel) (CAS #299-84-3 );
(V) 2,4,5-trichlorophenol (TCP) (CAS #95-95-4 ); or
(VI) Hexachlorophene (HCP) (CAS #70-30-4 ).
(F) Each applicant must report any pollutants listed in Table
				  V of Appendix D (certain hazardous substances) of 40 CFR Part 122 if they
				  believe the pollutants will be present in any outfall (no quantitative
				  estimates are required unless they are already available).
(G) No later than two (2) years after the commencement of the
				  discharge from a proposed facility, the applicant must submit analytical
				  results which characterize the actual effluent discharged. The applicant need
				  not submit this information to the extent the analytical results are reported
				  by the applicant under the discharge monitoring requirements of the applicant's
				  permit.
(v) Engineering report. Each applicant must report the
				  existence of any technical evaluation concerning the applicant's wastewater
				  treatment, along with the name and location of similar plants of which the
				  applicant has knowledge.
(vi) Other information. Any optional information the
				  permittee wishes to have considered.
