Section 3745-39-04 - Ohio EPA NPDES requirements for industries, including construction activities, and large and medium MS4s[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules and federal statutory provisions referenced in this rule, see rule 3745-39-01 of the Administrative Code.]
(A) Permit requirement. (1) The following discharges composed entirely of storm water shall require an Ohio NPDES permit: (a) A discharge with respect to which a permit has been issued prior to February 4, 1987.(b) A discharge associated with industrial activity (for discharges associated with industrial activity, see paragraph (A)(4) of this rule for additional requirements).(c) A discharge from a large municipal separate storm sewer system.(d) A discharge from a medium municipal separate storm sewer system.(e) A discharge that the director determines to contribute to a violation of an Ohio water quality standard or is a significant contributor of pollutants to surface waters of the state. This designation may include a discharge from any conveyance or system of conveyances used for collecting and conveying storm water runoff or a system of discharges from municipal separate storm sewers, except for those discharges from conveyances that may not require a permit under paragraph (A)(2) of this rule or agricultural storm water runoff that is exempted from the definition of point source. The director may designate discharges from municipal separate storm sewers on a system-wide or jurisdiction-wide basis. In making this determination the director may consider all of the following factors: (i) The location of the discharge with respect to surface waters of the state as defined in rule 3745-39-01 of the Administrative Code.(ii) The size of the discharge.(iii) The quantity and nature of the pollutants discharged to surface waters of the state.(iv) Other relevant factors.(2) The director may not require a permit for discharges of storm water runoff from either of the following:(a) Mining operations composed entirely of flows that are from conveyances or systems of conveyances (including, but not limited to, pipes, conduits, ditches and channels) used for collecting and conveying precipitation runoff and that are not contaminated by contact with, or that has not come into contact with, any overburden, raw material, intermediate product, finished product, byproduct or waste product located on the site of such operations, except in accordance with paragraph (C)(1)(d) of this rule.(b) All field activities or operations associated with oil and gas exploration, production, processing, or treatment operations or transmission facilities, including activities necessary to prepare a site for drilling and for the movement and placement of drilling equipment, whether or not such field activities or operations may be considered to be construction activities, except in accordance with paragraph (C)(1)(c) of this rule. [Comment: Ohio EPA encourages operators of oil and gas field activities or operations to implement and maintain best management practices (BMPs) to minimize discharges of pollutants, including sediment, in storm water both during and after construction activities to help ensure protection of surface water quality during storm events. Appropriate controls would be those suitable to the site conditions and consistent with generally accepted engineering design criteria and manufacturer specifications. Selection of BMPs could also be affected by seasonal or climate conditions.]
(3) Large and medium municipal separate storm sewer systems. (a) Permits shall be obtained for all discharges from large and medium municipal separate storm sewer systems.(b) The director may either issue one system-wide permit covering all discharges from municipal separate storm sewers within a large or medium municipal separate storm sewer system or issue distinct permits for appropriate categories of discharges within a large or medium municipal separate storm sewer system including, but not limited to: all discharges owned or operated by the same municipality; located within the same jurisdiction; all discharges within a system that discharge to the same watershed; discharges within a system that are similar in nature; or individual discharges from municipal separate storm sewers within the system.(c) The operator of a discharge from a municipal separate storm sewer that is part of a large or medium municipal separate storm sewer system shall complete one of the following: (i) Participate in a permit application (to be a permittee or a co-permittee) with one or more other operators of discharges from the large or medium municipal separate storm sewer system that covers all, or a portion of all, discharges from the municipal separate storm sewer system.(ii) Submit a distinct permit application that only covers discharges from the municipal separate storm sewers for which the operator is responsible.(iii) A regional authority may be responsible for submitting a permit application under all of the following guidelines:(a) The regional authority together with co-applicants shall have authority over a storm water management program that is in existence, or shall be in existence at the time part 1 of the municipal application is due.(b) The permit applicant or co-applicants shall establish their ability to make a timely submission of part 1 and part 2 of the municipal application.(c) Each of the operators of municipal separate storm sewers within the systems described in paragraphs (B)(4)(a) and (B(4)(b) of this rule or in paragraphs (B)(6)(a) and (B)(6)(b) of this rule, that are under the purview of the designated regional authority, shall comply with the application requirements of paragraph (D) of this rule.(d) One permit application may be submitted for all or a portion of all municipal separate storm sewers within adjacent or interconnected large or medium municipal separate storm sewer systems. The director may issue one system-wide permit covering all, or a portion of all, municipal separate storm sewers in adjacent or interconnected large or medium municipal separate storm sewer systems.(e) Permits for all or a portion of all discharges from large or medium municipal separate storm sewer systems that are issued on a system-wide, jurisdiction-wide, watershed or other appropriate basis may specify different conditions relating to different discharges covered by the permit, including different management programs for different drainage areas that contribute storm water to the system.(f) Co-permittees need only comply with permit conditions relating to discharges from the municipal separate storm sewers for which they are operators. If at any time, one or more MS4 decides to not continue as a co-permittee, such MS4 shall submit a permit application and SWMP to Ohio EPA. Such MS4 shall continue to operate under the existing co-permittee SWMP until their permit application and SWMP is approved.(4) Discharges through large and medium municipal separate storm sewer systems. In addition to meeting the requirements of paragraph (C) of this rule, an operator of a storm water discharge associated with industrial activity that discharges through a large or medium municipal separate storm sewer system shall submit, to the operator of the municipal separate storm sewer system receiving the discharge within one hundred eighty days prior to commencing such discharge: the name of the facility; a contact person and phone number; the location of the discharge; a description, including standard industrial classification, that best reflects the principal products or services provided by each facility; and any existing Ohio NPDES permit number or a copy of Ohio EPA's letter acknowledging receipt of the operator's no exposure certification. The same information is to be submitted to a small municipal separate storm sewer system by an operator of a storm water discharge associated with industrial activity that discharges through a small municipal separate storm sewer system once that system is an NPDES permitted discharger.(5) Other municipal separate storm sewers. The director may issue permits for municipal separate storm sewers that are designated under paragraph (A)(1)(e) of this rule on a system-wide basis, jurisdiction-wide basis, watershed basis or other appropriate basis, or may issue permits for individual discharges.(6) Combined sewer systems. Combined sewers, as defined in rule 3745-39-01 of the Administrative Code, are point sources that shall obtain Ohio NPDES permits in accordance with the procedures of rule 3745-33-03 of the Administrative Code and are not subject to the provisions of this rule.(7)(a) For discharges composed entirely of storm water, that are not required by paragraph (A)(1) of this rule to obtain a permit, operators shall be required to obtain an Ohio NPDES permit if any of the following apply: (i) The discharge is from a small municipal separate storm sewer system required to be regulated pursuant to rule 3745-39-03 of the Administrative Code.(ii) The discharge is a storm water discharge associated with small construction activity pursuant to paragraph (B)(14) of this rule.(iii) The director determines that storm water controls are needed for the discharge based on wasteload allocations that are part of total maximum daily loads (TMDLs) that address the pollutant of concern.(iv) The director determines that the discharge, or category of discharges within a geographic area, contributes to a violation of a water quality standard or is a significant contributor of pollutants to surface waters of the state.(b) Operators of small MS4s designated pursuant to paragraphs (A)(7)(a)(i), (A)(7)(a)(iii) and (A)(7)(a)(iv) of this rule shall seek coverage under an Ohio NPDES permit in accordance with rule 3745-39-03 of the Administrative Code. Operators of non-municipal sources designated pursuant to paragraphs (A)(7)(a)(ii), (A)(7)(a)(iii) and (A)(7)(a)(iv) of this rule shall seek coverage under an Ohio NPDES permit in accordance with paragraph (C)(1) of this rule.(c) Operators of storm water discharges designated pursuant to paragraphs (A)(7)(a)(iii) and (A)(7)(a)(iv) of this rule shall apply to the director for a permit within one hundred eighty days of receipt of notice, unless permission for a later date is granted by the director.(B) Definitions.

Small construction activity does not include routine maintenance that is performed to maintain the original line and grade, hydraulic capacity or original purpose of the facility. The director may waive the otherwise applicable requirements in a general permit for a storm water discharge from construction activities that disturb less than five acres where either paragraph (B)(14)(a)(i) or (B)(14)(a)(ii) of this rule apply: (i) The value of the rainfall erosivity factor ("R" in the revised universal soil loss equation) is less than five during the period of construction activity (see 40 C.F.R. 122.26(b)(15)(i)(A)). An operator shall certify to the director that the construction activity will take place during a period when the value of the rainfall erosivity factor is less than five.(ii) Storm water controls are not needed based on a TMDL approved or established by the director that addresses the pollutant of concern or, for non-impaired waters that do not require TMDLs, an equivalent analysis that determines allocations for small construction sites for the pollutant of concern or that determines that such allocations are not needed to protect water quality based on consideration of existing in-stream concentrations, expected growth in pollutant contributions from all sources and a margin of safety. For the purpose of this paragraph, the pollutant of concern include sediment or a parameter that addresses sediment (such as total suspended solids, turbidity or siltation) and any other pollutant that has been identified as a cause of impairment of any water body that will receive a discharge from the construction activity. The operator shall certify to the director that the construction activity will take place, and storm water discharges will occur, within the drainage area addressed by the TMDL or equivalent analysis.(iii) The director may require electronic reporting of this information.(b) Any other construction activity designated by the director, based on the potential for contribution to a violation of a water quality standard or for significant contribution of pollutants to surface waters of the state.(15) "Uncontrolled sanitary landfill" means a landfill or open dump, whether in operation or closed, that does not meet the requirements for run-on or runoff controls established pursuant to Chapter 3734. of the Revised Code.(C) Application requirements for storm water discharges associated with industrial activity and storm water discharges associated with small construction activity. (1) Individual application. Dischargers of storm water associated with industrial activity and with small construction activity are required to apply for an individual permit or seek coverage under a currently enforced storm water general permit (see Chapter 3745-38 of the Administrative Code for general permit application requirements). Facilities that are required to obtain an individual permit, or any discharge of storm water that the director is evaluating for designation under paragraph (A)(1)(e) of this rule and is not a municipal separate storm sewer, shall submit an Ohio NPDES application as modified and supplemented by the following provisions: (a) Except as provided in paragraphs (C)(1)(b) to (C)(1)(d) of this rule, the operator of a storm water discharge associated with industrial activity subject to this rule shall provide all of the following: (i) A site map showing topography (or indicating the outline of drainage areas served by the outfall or outfalls covered in the application if a topographic map is unavailable) of the facility including: each of its drainage and discharge structures; the drainage area of each storm water outfall; paved areas and buildings within the drainage area of each storm water outfall; each past or present area used for outdoor storage or disposal of significant materials; each existing structural control measure to reduce pollutants in storm water runoff; materials loading and access areas; areas where pesticides, herbicides, soil conditioners and fertilizers are applied; each of its hazardous waste treatment, storage or disposal facilities (including each area not required to have a permit under a federal law, other than the act, that is used for accumulating hazardous waste under Chapter 3734. of the Revised Code); each well where fluids from the facility are injected underground; and springs and other surface water bodies that receive storm water discharges from the facility.(ii) An estimate of the area of impervious surfaces (including paved areas and building roofs) and the total area drained by each outfall (within a mile radius of the facility) and a narrative description of the following: significant materials that in the three years prior to the submittal of this application have been treated, stored or disposed in a manner to allow exposure to storm water; method of treatment, storage or disposal of such materials; materials management practices employed, in the three years prior to the submittal of this application, to minimize contact by these materials with storm water runoff; materials loading and access areas; the location, manner and frequency in which pesticides, herbicides, soil conditioners and fertilizers are applied; the location and a description of existing structural and non-structural control measures to reduce pollutants in storm water runoff; and a description of the treatment the storm water receives, including the ultimate disposal of any solid or fluid wastes other than by discharge.(iii) A certification that all outfalls that should contain storm water discharges associated with industrial activity have been tested or evaluated for the presence of non-storm water discharges that are not covered by an Ohio NPDES permit; tests for such non-storm water discharges may include smoke tests, fluorometric dye tests, analysis of accurate schematics, as well as other appropriate tests.

"No exposure" means that all industrial materials and activities are protected by a storm resistant shelter to prevent exposure to rain, snow, snowmelt or runoff. Industrial materials or activities include, but are not limited to, material handling equipment or activities, industrial machinery, raw materials, intermediate products, by-products, final products or waste products. Material handling activities include the storage, loading and unloading, transportation or conveyance of any raw material, intermediate product, final product or waste product.
(1) Qualification. To qualify for this exclusion, the operator of the discharge shall complete the following: (a) Provide a storm resistant shelter to protect industrial materials and activities from exposure to rain, snow, snow melt and runoff.(b) Complete and sign (according to 40 C.F.R. 122.22) a certification that there are no discharges of storm water contaminated by exposure to industrial materials and activities from the entire facility, except as provided in paragraph (G)(2) of this rule.(c) Submit the signed certification to the director once every five years. The director may require electronic reporting of this information.(d) Allow the director to inspect the facility to determine compliance with the "no exposure" conditions.(e) Allow the director to make any "no exposure" inspection reports available to the public upon request.(f) For facilities that discharge through an MS4, upon request, submit a copy of the certification of "no exposure" to the MS4 operator, as well as allow inspection and public reporting by the MS4 operator.(2) Industrial materials and activities not requiring storm resistant shelter. To qualify for this exclusion, storm resistant shelter is not required for any of the following:(a) Drums, barrels, tanks, and similar containers that are tightly sealed, provided those containers are not deteriorated and do not leak ("sealed" means banded or otherwise secured and without operational taps or valves).(b) Adequately maintained vehicles used in material handling.(c) Final products, other than products that would be mobilized in storm water discharge (e.g., rock salt).(3) Limitations.

If a facility has some discharges of storm water that would otherwise be "no exposure" discharges, individual permit requirements may be adjusted accordingly.(c) If circumstances change and industrial materials or activities become exposed to rain, snow, snow melt or runoff, the conditions for this exclusion no longer apply. In such cases, the discharge becomes subject to enforcement for un-permitted discharge. Any conditionally exempt discharger who anticipates changes in circumstances shall apply for and obtain permit authorization prior to the change of circumstances.(d) Notwithstanding the provisions of paragraphs (G)(3)(a) to (G)(3)(c) of this rule, the director retains the authority to require permit authorization (and deny this exclusion) upon making a determination that the discharge causes, has a reasonable potential to cause or contributes to an in stream excursion above an applicable water quality standard, including designated uses. (4) Certification. At a minimum, the "no exposure" certification shall require the submission of all of the following information to aid the director in determining if the facility qualifies for the "no exposure" exclusion: (a) The legal name, address and phone number of the discharger.(b) The facility name and address, the county name and the latitude and longitude where the facility is located.(c) The certification shall indicate that none of the following materials or activities are, or will be in the foreseeable future, exposed to precipitation: (i) Using, storing or cleaning industrial machinery or equipment, and areas where residuals from using, storing or cleaning industrial machinery or equipment remain and are exposed to storm water.(ii) Materials or residuals on the ground or in storm water inlets from spills or leaks.(iii) Materials or products from past industrial activity.(iv) Material handling equipment (except adequately maintained vehicles).(v) Materials or products during loading or unloading or transporting activities.(vi) Materials or products stored outdoors (except final products intended for outside use; e.g., new cars, where exposure to storm water does not result in the discharge of pollutants).(vii) Materials contained in open, deteriorated or leaking storage drums, barrels, tanks, and similar containers.(viii) Materials or products handled or stored on roads or railways owned or maintained by the discharger.(ix) Waste material (except waste in covered, non-leaking containers; e.g., dumpsters).(x) Application or disposal of process wastewater (unless otherwise permitted).(xi) Particulate matter or visible deposits of residuals from roof stacks or vents not otherwise regulated; i.e., under an air quality control permit and evident in the storm water outflow.(d) All "no exposure" certifications shall include the following certification statement, and be signed in accordance with the signatory requirements of 40 C.F.R. 122.22: "I certify under penalty of law that I have read and understand the eligibility requirements for claiming a condition of "no exposure" and obtaining an exclusion from Ohio NPDES storm water permitting; and that there are no discharges of storm water contaminated by exposure to industrial activities or materials from the industrial facility identified in this document (except as allowed under paragraph (G)(2) of rule 3745-39-04 of the Administrative Code). I understand that I am obligated to submit a "no exposure" certification form once every five years to the Ohio EPA director and, if requested, to the operator of the local MS4 into which this facility discharges (where applicable). I understand that I shall allow the Ohio EPA director, or MS4 operator where the discharge is into the local MS4, to perform inspections to confirm the condition of "no exposure" and to make such inspection reports publicly available upon request.
