Wyoming Administrative Code › Agency 020 - Environmental Quality, Dept. of › Sub-Agency 0011 - Water Quality › Chapter 2 - DISCHARGES, PERMIT REGS › Appendix D - Additional Requirements Applicable to Manufacturing, Commercial, Mining and Silvicultural Facilities Discharging Only Non-process Waste Water

Current through July 13, 2024
(a) Application requirements. Application requirements for
				  manufacturing, commercial, mining and silvicultural facilities which discharge
				  only non-process wastewater. Except for storm water discharges, all
				  manufacturing, commercial, mining, and silvicultural dischargers applying for
				  permits which discharge only non-process wastewater not regulated by an
				  effluent limitation guideline or new source performance standard shall provide
				  the following information, in addition to that described in Section
				  5(a) (v), to the administrator, using application forms
				  provided by the administrator.
(i) Discharge date (for new dischargers). Date of expected
				  commencement of discharge.
(ii) Type of waste. An identification of the general type of
				  waste discharged, or expected to be discharged upon commencement of operations,
				  including sanitary wastes, restaurant or cafeteria wastes, or noncontact
				  cooling water. An identification of cooling water additives (if any) that are
				  used or expected to be used upon commencement of operations, along with their
				  composition if existing composition is available.
(iii) Effluent characteristics.
(A) Quantitative data for the pollutants or parameters listed
				  below, unless testing is waived by the administrator.
(I) Biochemical Oxygen Demand
				  (BOD5),
(II) Total Suspended Solids (TSS),
(III) Fecal Coliform (if believed present or if sanitary
				  waste is or will be discharged),
(IV) Total Residual Chlorine (if chlorine is used),
(V) Oil and Grease,
(VI) Chemical Oxygen Demand (COD)(if non-contact cooling
				  water is or will be discharged),
(VII) Ammonia (as N),
(VIII) Discharge Flow,
(IX) pH,
(X) Temperature (Winter and Summer), and
(XI) Total Organic Carbon (TOC).
(B) The quantitative data in Appendix D (a) (iii) (A) may be
				  data collected over the past 365 days, if they remain representative of current
				  operations, and must include daily maximum value, daily average value, and
				  number of measurements taken. The applicant must collect and analyze samples in
				  accordance with 40 CFR Part 136. Grab samples must be used for pH, temperature,
				  oil and grease, total residual chlorine, and fecal coliform. For all other
				  pollutants, 24-hour composite samples must be used. New dischargers must
				  include estimates for the pollutants or parameters listed below instead of
				  actual sampling data, along with the source of each estimate. All levels must
				  be reported or estimated as concentration and as total mass, except for flow,
				  pH, and temperature.
(C) The administrator may waive the testing and reporting
				  requirements for any of the pollutants or flow listed in paragraph (a) (iii) of
				  this appendix if the applicant submits a request for such a waiver before or
				  with the permit application which demonstrates that information adequate to
				  support issuance of a permit can be obtained through less stringent
				  requirements.
(D) If the applicant is a new discharger, the applicant must
				  provide quantitative data in accordance with paragraph (a) (iii) of this
				  appendix no later than two (2) years after commencement of discharge. However,
				  the applicant need not perform tests which they have already performed and
				  reported under the discharge monitoring requirements of the applicant's
				  permit.
(E) The requirements of paragraph (a) (iii) of this appendix
				  do not apply for pollutants present in a discharge solely as a result of their
				  presence in intake water. However, an applicant must report such pollutants as
				  present. Net credit may be provided for the presence of pollutants in intake
				  water if the requirements are met.
(iv) Flow. A description of the frequency of flow and
				  duration of any seasonal or intermittent discharge (except for storm water
				  runoff, leaks, or spills).
(v) Treatment system. A brief description of any system used
				  or to be used.
(vi) Optional information. Any additional information the
				  applicant wishes to be considered.
