17.30.1322    APPLICATION FOR A PERMIT

(1) Any person who discharges or proposes to discharge pollutants and who does not have an effective permit, except persons covered by general permits under ARM 17.30.1341, excluded under ARM 17.30.1310, or a user of a privately owned treatment works unless the department requires otherwise under ARM 17.30.1344, shall submit a complete application to the department in accordance with this rule and ARM 17.30.1364 and 17.30.1365, 17.30.1370 through 17.30.1379, and 17.30.1383.

(a) All applicants for MPDES permits shall submit applications on department permit application forms. More than one application form may be required from a facility depending on the number and types of discharges or outfalls found there. Application forms may be obtained by contacting the Water Protection Bureau at (406) 444-5546; Department of Environmental Quality, Water Protection Bureau, 1520 East Sixth Avenue, P.O. Box 200901, Helena, MT 59620-0901; or on the department's web site at http://deq.mt.gov/default.mcpx.

(b) All applicants, other than publicly owned treatment works (POTWs), shall submit Form 1.

(c) Applicants for new and existing POTWs shall submit the information required in (12) using Form 2A.

(d) Applicants for concentrated animal feeding operations or concentrated aquatic animal production facilities shall submit Form 2B.

(e) Applicants for existing industrial facilities, including manufacturing facilities, commercial facilities, mining activities, and silvicultural activities, shall submit Form 2C.

(f) Applicants for new industrial facilities that discharge process wastewater shall submit Form 2D.

(g) Applicants for new and existing industrial facilities that discharge only non-process wastewater shall submit Form 2E.

(h) Applicants for new and existing facilities, whose discharge is composed entirely of storm water associated with industrial activity, shall submit Form 2F, unless exempted by (11)(b) through (d). If the discharge is composed of storm water and non-storm water, the applicant shall also submit Forms 2C, 2D, and/or 2E, as appropriate, in addition to Form 2F.

(i) Applicants for new cooling water intake structures shall submit the information required in (17) in addition to any forms required in (e) through (g).

(2) When a facility or activity is owned by one person but is operated by another person, it is the operator's duty to obtain a permit.

(3) Any person proposing a new discharge shall submit an application at least 180 days before the date on which the discharge is to commence, unless permission for a later date has been granted by the department. Persons proposing a new discharge are encouraged to submit their applications well in advance of the 180-day requirement to avoid delay. See also (13) through (15) requiring time frames where a variance may be available.

(4) Any permittee with a currently effective permit shall submit a new application at least 180 days before the expiration date of the existing permit, unless permission for a later date has been granted by the department. The department may not grant permission for applications to be submitted later than the expiration date of the existing permit.

(5) The department may not issue a permit before receiving a complete application for a permit except for MPDES general permits. An application for a permit is complete when the department receives an application form and any supplemental information which are completed to the department's satisfaction. The completeness of any application for a permit must be judged independently of the status of any other permit application or permit for the same facility or activity.

(6) All applicants for MPDES permits, other than POTWs, shall provide the following information to the department, using the department's application Form 1. Additional information required of applicants is set forth in (7) through (17):

(a) the activities conducted by the applicant which require it to obtain an MPDES permit;

(b) name, mailing address, and location of the facility for which the application is submitted;

(c) up to four standard industrial category (SIC) codes and up to four North American Industry Classification System (NAICS) codes which best reflect the principal products or services provided by the facility;

(d) the operator's name, address, telephone number, electronic mail address, ownership status, and status as federal, state, private, public, or other entity;

(e) whether the facility is located on Indian lands; 

(f) a listing of all permits or construction approvals received or applied for under any of the following programs:

(i) hazardous waste management program under the Resource Conservation and Recovery Act of 1976 (42 USC 6901, et seq.) (RCRA);

(ii) underground injection control (UIC) program under the federal Safe Drinking Water Act (SDWA);

(iii) MPDES program under the federal Clean Water Act;

(iv) prevention of significant deterioration (PSD) program under the Montana Clean Air Act;

(vii) ocean dumping permits under the Marine Protection Research and Sanctuaries Act;

(viii) dredge or fill permits under section 404 of the federal Clean Water Act; and

(ix) other relevant state or federal environmental permits;

(g) a topographic map, or other map if a topographic map is unavailable, extending one mile beyond the property boundaries of the source, depicting:

(i) the facility and each of its intake and discharge structures;

(ii) each of its hazardous waste treatment, storage, or disposal facilities;

(iii) each well where fluids from the facility are injected underground; and

(iv) those wells, springs, other surface water bodies, and drinking water wells listed in public records or otherwise known to the applicant in the map area;

(h) a brief description of the nature of the business;

(i) an indication of whether the facility uses cooling water and the source of the cooling water; and

(j) an indication of whether the facility is requesting any of the variances at (13), if known at the time of the application.

(7) Existing manufacturing, commercial, mining, and silvicultural dischargers applying for MPDES permits, except for those facilities subject to the requirements of (8), shall provide the following information to the department, using application forms provided by the department:

(a) the latitude and longitude of the outfall to the nearest 15 seconds and the name of the receiving water;

(b) 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 (c). 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 (for example, for certain mining activities), the applicant may provide instead a pictorial description of the nature and amount of any sources of water and any collection and treatment measures; 

(c) a narrative identification of each type of process, operation, or production area that contributes wastewater to the effluent for each outfall, including process wastewater, cooling water, and storm water runoff; the average flow that 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. Processes, operations, or production areas may be described in general terms (for example, "dye-making reactor," "distillation tower"). 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;

(d) if any of the discharges described in (c) 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);

(e) if an effluent guideline adopted under ARM 17.30.1207 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 ARM 17.30.1345;

(f) 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;

(g) information on the effluent characteristics of pollutants specified in this subsection, except information on storm water discharges that is specified in (11)(b), must be provided according to the following: 

(i) when "quantitative data" for a pollutant are required, the applicant shall collect a sample of effluent and analyze it for the pollutant in accordance with analytical methods approved under 40 CFR Part 136, unless use of another method is required for the pollutant under 40 CFR subchapter N. When no analytical method is approved under Part 136 or required under subchapter N, the applicant may use any suitable method, but shall provide a description of the method. When an applicant has two or more outfalls with substantially identical effluents, the department may allow the applicant to test only one outfall and report that the quantitative data also apply to the substantially identical outfalls. The requirements in (vi), (vii), and (viii), that state that an applicant shall 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 shall report such pollutants as present. Grab samples must be used for pH, temperature, cyanide, total phenols, residual chlorine, oil and grease, and fecal coliform, including Escherichia coli (E-coli). For all other pollutants, a 24-hour composite sample, using a minimum of four grab samples, must be used, unless specified otherwise at 40 CFR Part 136. 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. In addition, for discharges other than storm water discharges, the department may waive composite sampling for any outfall for which the applicant demonstrates that the use of an automatic sampler is infeasible and that the minimum of four grab samples will be a representative sample of the effluent being discharged. Results of analyses of individual grab samples for any parameter may be averaged to obtain the daily average. Grab samples that are not required to be analyzed immediately (see Table II at 40 CFR 136.3(e)) may be composited in the laboratory, provided that container, preservation, and holding time requirements are met (see Table II at 40 CFR 136.3 (e)) and that sample integrity is not compromised by compositing; 

(ii) for storm water discharges, all samples must be collected from the discharge resulting from a storm event that is greater than 0.1 inch and at least 72 hours from the previously measurable (greater than 0.1 inch rainfall) storm event. Where feasible, the variance in the duration of the event and the total rainfall of the event should not exceed 50 percent from the average or median rainfall event in that area. For all applicants, a flow-weighted composite must be taken for either the entire discharge or for the first three hours of the discharge. The flow-weighted composite sample for a storm water discharge may be taken with a continuous sampler or as a combination of a minimum of three sample aliquots taken in each hour of discharge for the entire discharge or for the first three hours of the discharge, with each aliquot being separated by a minimum period of 15 minutes. However, a minimum of one grab sample may be taken for storm water discharges from holding ponds or other impoundments with a retention period greater than 24 hours. For a flow-weighted composite sample, only one analysis of the composite of aliquots is required. For storm water discharge samples taken from discharges associated with industrial activities, quantitative data must be reported for the grab sample taken during the first 30 minutes, or as soon thereafter as practicable, of the discharge for all pollutants specified in (11)(e). For all storm water permit applicants taking flow-weighted composites, quantitative data must be reported for all pollutants specified in (11)(e) except pH, temperature, cyanide, total phenols, residual chlorine, oil and grease, fecal coliform, and fecal streptococcus. The department may allow or establish appropriate site-specific sampling procedures or requirements, including sampling locations, the season in which the sampling takes place, the minimum duration between the previous measurable storm event and the storm event sampled, the minimum or maximum level of precipitation required for an appropriate storm event, the form of precipitation sampled (snow melt or rain fall), protocols for collecting samples under 40 CFR Part 136, and additional time for submitting data on a case-by-case basis. 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. For example, any pesticide manufactured by a facility may be expected to be present in contaminated storm water runoff from the facility;

(iii) every applicant shall report quantitative data for every outfall for the following pollutants:

(A) biochemical oxygen demand;

(B) chemical oxygen demand;

(C) total organic carbon;

(D) total suspended solids;

(E) ammonia (as N);

(F) temperature (both winter and summer); and

(G) pH;

(iv) the department may waive the reporting requirements for individual point sources or for a particular industry category for one or more of the pollutants listed in the above subsection if the applicant has demonstrated that such a waiver is appropriate because information adequate to support issuance of a permit can be obtained with less stringent requirements;

(v) each applicant with processes in one or more primary industry category (see Appendix A of 40 CFR Part 122) contributing to a discharge shall report quantitative data for the following pollutants in each outfall containing process wastewater:

(A) the organic toxic pollutants in the fractions designated in Table I of Appendix D of 40 CFR Part 122 for the applicant's industrial category or categories unless the applicant qualifies as a small business under (7)(h). Table II of Appendix D of 40 CFR Part 122 lists the organic toxic pollutants in each fraction. The fractions result from the sample preparation required by the analytical procedure which uses gas chromatography/mass spectrometry. A determination that an applicant falls within a particular industrial category for the purposes of selecting fractions for testing is not conclusive as to the applicant's inclusion in that category for any other purposes; and

(B) the pollutants listed in Table III of Appendix D of 40 CFR Part 122 (the toxic metals, cyanide, and total phenols);

(vi) each applicant shall indicate whether it knows or has reason to believe that any of the pollutants in Table IV of Appendix D of 40 CFR Part 122 (certain conventional and nonconventional pollutants) is discharged from each outfall. If an applicable effluent limitations guideline either directly limits the pollutant or, by its express terms, indirectly limits the pollutant through limitations on an indicator, the applicant shall report quantitative data. For every pollutant discharged which is not so limited in an effluent limitations guideline, the applicant shall either report quantitative data or briefly describe the reasons the pollutant is expected to be discharged;

(vii) each applicant shall indicate whether it knows or has reason to believe that any of the pollutants listed in Table II or Table III of Appendix D of 40 CFR Part 122 (the toxic pollutants and total phenols) for which quantitative data are not otherwise required under (7)(g)(v), is discharged from each outfall. For every pollutant expected to be discharged in concentrations of ten ppb or greater, the applicant shall report quantitative data. For acrolein, acrylonitrile, 2,4-dinitrophenol, and 2-methyl 4,6-dinitrophenol, where any of these four pollutants are expected to be discharged in concentrations of 100 ppb or greater, the applicant shall report quantitative data. For every pollutant expected to be discharged in concentrations less than ten ppb, or in the case of acrolein, acrylonitrile, 2,4-dinitrophenol, and 2-methyl 4,6-dinitrophenol, in concentrations less than 100 ppb, the applicant shall either submit quantitative data or briefly describe the reasons the pollutant is expected to be discharged. An applicant qualifying as a small business under (7)(h) is not required to analyze for pollutants listed in Table II of Appendix D of 40 CFR Part 122 (the organic toxic pollutants);

(viii) each applicant shall indicate whether it knows or has reason to believe that any of the pollutants in Table V of Appendix D of 40 CFR Part 122 (certain hazardous substances and asbestos) are discharged from each outfall. For every pollutant expected to be discharged, the applicant shall briefly describe the reasons the pollutant is expected to be discharged, and report any quantitative data it has for any pollutant;

(ix) each applicant shall report qualitative data, generated using a screening procedure not calibrated with analytical standards, for 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) if it:

(A) uses or manufactures 2,4,5-trichlorophenoxy acetic acid (2,4,5-T); 2-(2,4,5-trichlorophenoxy) propanoic acid (Silvex, 2,4,5-TP); 2-(2,4,5-trichlorophenoxy) ethyl 2,2-dichloropropionate (Erbon); O,O-dimethyl O-(2,4,5-trichlorophenyl) phosphorothioate (Ronnel); 2,4,5-trichlorophenol (TCP); or hexachlorophene (HCP); or

(B) knows or has reason to believe that TCDD is or may be present in an effluent;

(x) where quantitative data are required in (7)(g)(i) through (ix), existing data may be used, if available, in lieu of sampling done solely for the purpose of application, provided that:

(A) all data requirements are met; sampling was performed, collected, and analyzed no more than four and one-half years prior to submission;

(B) all data are representative of the discharge; and

(C) all available representative data are considered in the values reported;

(h) an applicant which qualifies as a small business under one of the following criteria is exempt from the requirements in (7)(g)(v)(A) or (vi) to submit quantitative data for the pollutants listed in Table II of Appendix D of 40 CFR Part 122 (the organic toxic pollutants):

(i) for coal mines, a probable total annual production of less than 100,000 tons per year;

(ii) for all other applicants, gross total annual sales averaging less than $100,000 per year (in second quarter 1980 dollars);

(i) a listing of any toxic pollutant which the applicant currently uses or manufactures as an intermediate or final product or byproduct. The department may waive or modify this requirement for any applicant if the applicant demonstrates that it would be unduly burdensome to identify each toxic pollutant and the department has adequate information to issue the permit;

(j) an identification of any biological toxicity tests which the applicant knows or has reason to believe have been made within the last three years on any of the applicant's discharges or on a receiving water in relation to a discharge;

(k) if a contract laboratory or consulting firm performed any of the analyses required by (7)(g), the identity of each laboratory or firm and the analyses performed;

(l) in addition to the information reported on the application form, applicants shall provide to the department, at its request, such other information as the department may reasonably require to assess the discharges of the facility and to determine whether to issue an MPDES permit. The additional information may include additional quantitative data and bioassays to assess the relative toxicity of discharges to aquatic life and requirements to determine the cause of the toxicity.

(8) Except for storm water discharges, all manufacturing, commercial, mining, and silvicultural dischargers applying for MPDES permits that discharge only non-process wastewater not regulated by an effluent limitations guideline or new source performance standard shall provide the following information to the department, using application forms provided by the department:

(a) outfall number, latitude, and longitude to the nearest 15 seconds, and the name of the receiving water;

(b) date of expected commencement of discharge (for new dischargers); 

(c) 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;

(d) quantitative data for the pollutants or parameters listed below, unless testing is waived by the department. The quantitative data may be data collected over the past 365 days, if they remain representative of current operations, and must include maximum daily value, average daily value, and number of measurements taken. The applicant shall 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, including E-coli. For all other pollutants, a 24-hour composite sample, using a minimum of four grab samples, must be used, unless specified otherwise at 40 CFR Part 136. For a composite sample, only one analysis of the composite aliquots is required. New dischargers shall 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.

(i) The requirements of (d) apply to:

(A) biochemical oxygen demand (BOD5);

(K) temperature (winter and summer); and

(L) any pollutant not listed above, if the pollutant is present in the effluent and regulated by a state-adopted water quality standard;

(ii) The department may waive the testing and reporting requirements for any of the pollutants or flow listed in (i) if the applicant submits a request for such a waiver before or with the application that demonstrates that information adequate to support issuance of a permit can be obtained through less stringent requirements.

(iii) If the applicant is a new discharger, the applicant shall complete forms provided by the department by providing quantitative data in accordance with (d) no later than two years after commencement of discharge. However, the applicant need not complete those portions of the forms requiring tests that the applicant has already performed and reported under the discharge monitoring requirements of the MPDES permit.

(iv) The requirements of (d) and (d)(iii), that an applicant shall provide quantitative data or estimates of certain pollutants, do not apply to pollutants present in a discharge solely as a result of their presence in intake water. However, an applicant shall report such pollutants as present. Net credit may be provided for the presence of pollutants in intake water if the requirements of ARM 17.30.1345(9) are met;

(e) a description of the frequency of flow and duration of any seasonal or intermittent discharge (except for storm water runoff, leaks, or spills);

(f) a brief description of any treatment system used or to be used;

(g) any additional information the applicant wishes to be considered, such as influent data for the purpose of obtaining "net" credits pursuant to ARM 17.30.1345(9); and

(i) a narrative description and scaled drawings showing the physical configuration of all source water bodies used by the facility, including areal dimensions, depths, salinity and temperature regimes, and other documentation that supports a determination of the water body type where each cooling water intake structure is located;

(ii) identification and characterization of the source water body's hydrological and geomorphological features, as well as the methods used to conduct any physical studies to determine the intake's area of influence within the water body and the results of such studies; and

(iii) locational maps;

(b) cooling water intake structure data, which includes:

(i) a narrative description of the configuration of each of the facility's cooling water intake structures and where they are located in the water body and in the water column;

(ii) latitude and longitude in degrees, minutes, and seconds for each of the cooling water intake structures;

(iii) a narrative description of the operation of each of the facility's cooling water intake structures, including design intake flows, daily hours of operation, number of days of the year in operation and seasonal changes, if applicable;

(iv) a flow distribution and water balance diagram that includes all sources of water to the facility, recirculating flows, and discharges; and

(v) engineering drawings of the cooling water intake structures; and

(c) a source water baseline biological characterization including information required to characterize the biological community in the vicinity of the cooling water intake structures and to characterize the operation of the cooling water intake structures. The department may also use this information in subsequent permit renewal proceedings to determine if the facility's design and construction technology plan, as required in ARM 17.30.1213, should be revised. This supporting information must include existing data (if they are available). However, supplemental data using newly conducted field studies may also be submitted at the discretion of the applicant. The following information must be submitted:

(i) a list of the data in (ii) through (vi) that are not available and efforts made to identify sources of the data;

(ii) a list of species (or relevant taxa) for all life stages and their relative abundance in the vicinity of the cooling water intake structures; 

(iii) identification of the species and life stages that would be most susceptible to impingement and entrainment. Species evaluated should include the forage base as well as those most important in terms of significance to commercial and recreational fisheries;

(iv) identification and evaluation of the primary period of reproduction, larval recruitment, and period of peak abundance for relevant taxa;

(v) data representative of the seasonal and daily activities (e.g., feeding and water column migration) of biological organisms in the vicinity of the cooling water intake structures;

(vi) identification of all threatened, endangered, and other protected species that might be susceptible to impingement and entrainment at the cooling water intake structures;

(vii) documentation of any public participation or consultation with federal or state agencies undertaken in development of the plan; and

(viii) if information is submitted to supplement the information requested in (i) with data collected using field studies, supporting documentation for the source water baseline biological characterization must include a description of all methods and quality assurance procedures for sampling, and data analysis including a description of the study area, taxonomic identification of sampled and evaluated biological assemblages (including all life stages of fish and shellfish), and sampling and data analysis methods. The sampling and/or data analysis methods used must be appropriate for a quantitative survey and based on consideration of methods used in other biological studies performed within the same source water body. The study area should include, at a minimum, the area of influence of the cooling water intake structure.

(18) The board adopts and incorporates by reference the following federal regulations as part of the Montana pollutant discharge elimination system. Copies of these federal regulations may be obtained from the Department of Environmental Quality, P.O. Box 200901, Helena, MT 59620-0901.

(a) 40 CFR Part 136 (July 1, 2015), which sets forth guidelines establishing test procedures for the analysis of pollutants;

(b) Appendix A to 40 CFR Part 122 (July 1, 2011), which sets forth a list of primary industrial categories;

(c) Appendix D to 40 CFR Part 122 (July 1, 2011), which sets forth NPDES permit application testing requirements;

(d) Appendix J to 40 CFR Part 122 (July 1, 2011), which sets forth NPDES permit testing requirements for publicly owned treatment works;

(e) 40 CFR Part 125 (July 1, 2011), which sets forth criteria for extending compliance dates and for determining the availability of a variance;

(f) 40 CFR Part 412 (July 1, 2011), which sets forth effluent guidelines and standards for concentrated animal feeding operations.
