Below, EPA answers common questions on the construction stormwater permitting program. GENERAL PROGRAM PROVISIONS 22-101. Note that operators must document in their SWPPP their rationale as to why it is infeasible to comply with the buffer requirements in Part 7.2.6(b)(i)(e), and describe any buffer width retained and/or supplemental erosion and sediment controls installed. Stormwater Pollution Prevention Plan (SWPPP) and all required permits The final plan deliverable must have the highest level of credibility based upon data-driven, expert analysis. Chapter 47. Operators on small lots must first determine their sites sediment risk level (i.e., High, Moderate, or Low) based on their location, soil type, and slope using the tables provided in Appendix G in the proposed permit. EPAs current definition for qualified person is written broadly to allow flexibility for the multiple types of projects covered under the CGP. To be authorized under the CGP, the operator must meet the eligibility requirements specified in Part 1.1 of the permit. Construction activities, as defined in Appendix A of the 2017 EPA CGP, includes earth-disturbing activities, such as the clearing, grading, and excavation of land, and other construction-related activities (e.g., stockpiling of fill materials; placement of raw materials at the site) that could lead to the generation of pollutants. For example, after a house is built and occupied, any future construction on that lot (e.g., reconstructing after fire, adding a pool or parking area for a boat), would stand alone as a new common plan for purposes of calculating acreage disturbed to determine if a permit is required. EPA finalized the Effluent Limitations Guidelines and New Source Performance Standards for the construction and development industry (i.e., the C&D rule) on December 1, 2009. another operators site) to be complete before submitting an NOT. For instance, if an operator commences work on a 20-acre project by clearing and grading a 5-acre portion of the site, and while that construction is ongoing and prior to stabilization the operator clears and grades another 3-acre area, for example, the operator would be required to comply with the 7-day stabilization deadline because the amount of disturbed area on the site at any one time exceeds the 5-acre threshold. The following regulations applicable to oil and gas construction activities are currently in effect: 40 CFR 122.26(a)(2) The Director may not require a permit for discharges of storm water runoff from mining operations or oil and gas exploration, production, processing or treatment operations or transmission facilities, composed entirely of flows which 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 which are not contaminated by contact with or that has not come into contact with, any overburden, raw material, intermediate products, finished product, byproduct or waste products located on the site of such operations. Examples include, but are not limited to, rip-rap, gravel, gabions, and geotextiles. For example, if you originally estimated less than 5 acres would actually be disturbed and took advantage of the "R" Factor waiver, but you actually disturbed 5.5 acres, you would lose your waiver and may have to go through the permit process mid-stream. These permits are designed to address water pollution that occurs from stormwater runoff from both industrial and municipal sources. . JavaScript appears to be disabled on this computer. A .gov website belongs to an official government organization in the United States. Where there are multiple operators associated with the same project, all operators must obtain permit coverage. Is a Stormwater Permit Required for Your Construction Project? A copy will be required to be submitted to EPA, if requested, pursuant to 40 CFR 122.22(c) and Appendix I, Section I.11.2.3 of the proposed 2017 EPA CGP. Operators must provide the following in their NOI for coverage under the 2017 EPA CGP: Approval to use a paper NOI form if granted a waiver from electronic reporting by an EPA Regional Office; Chemical treatment information, if applicable; Endangered species protection information; Any operator of an eligible site that must obtain permit coverage must submit an NOI to be covered under the permit. Large construction activities which disturb 5 or more acres, or are part of a larger common plan of development or sale that will disturb 5 or more acres, are regulated under this general permit. The electronic records and their associated metadata remain available and the operator can demonstrate that the records have not been changed in any modification of the recordkeeping system or migration to a successor recordkeeping system; Clear instructions guide users of the electronic recordkeeping system in proper use of the system and unambiguously communicate the legal significance of using an electronic signature device; and. Virginia Stormwater Management Program (VSMP) Regulation 1362(24). indicating construction activities may occur on a specific plot. that can lead to flooding or polluted stormwater . Section 320. This is intended to help operators understand the permit. In addition to seeding or planting the area to be vegetatively stabilized in arid and semi-arid areas, to the extent necessary to prevent erosion on the seeded or planted area, you must apply non-vegetative erosion controls that provide cover for at least three years without active maintenance by you. As water runs off these surfaces, it can pick up pollutants that contaminate local water bodies. . Therefore, the State seeks an experienced firm that is familiar with these types of projects and can work within the intent of the program. A principal executive officer of a federal agency includes (i) the chief executive officer of the agency, or (ii) a senior executive officer having responsibility for the overall operations of a principal geographic unit of the agency (e.g., Regional Administrator of EPA). Alternatively, the operator can choose to establish a smaller buffer or no buffer, if establishing a 50-foot or any buffer is infeasible, as long as other controls are implemented that ensure that the equivalent level of sediment load reduction is achieved as a 50-foot natural buffer. For instance, if an operator completes stabilization of 2 acres of land on a 5-acre disturbance, then 2 additional acres could be disturbed while still qualifying for the longer 14-day stabilization deadline. Section 310. If you have limitations regarding available computer access or computer capability. The following annual permit maintenance fees apply to each state permit identified below, including expired state permits that have been administratively continued. This would also apply to similar situations at an industrial facility, such as adding new buildings, a pipeline, or new wastewater treatment facility that was not part of the original plan. One landowner's wastewater plan raises worry for Central Texas water These considerations, in addition to EPAs research, led EPA to the conclusion that the use of cationic treatment chemicals at construction sites is best managed if its proposed use is subject to a greater degree of individualized review. Questions and answers are organized into the following categories: Every effort has been made to ensure the accuracy of the information on this page. Stormwater Permits - Texas Commission on Environmental Quality The permit requires operators of linear construction sites to retain as much natural buffer as feasible, and/or to the extent feasible provide supplemental erosion and sediment controls in the buffer area. SWPPPs, inspection reports, corrective action reports, and other permit documents can be signed by the person authorized to sign/certify the NOI (see Q&A above), or by a duly authorized representative of the person authorized to sign/certify the NOI, pursuant to 40 CFR 122.22(b) and Appendix I, Section I.11.2 of the 2017 EPA CGP. These waivers are authorized by federal regulation at 40 CFR 122.26(b)(15)(i)(A) & (B) and are explained in Appendix C of the permit. What is a New Jersey Stormwater Permit & do I need a NJPDES permit? Submit a Notice of Intent (NOI) 21 days prior to initiation of construction (45 days if within the Big Darby Creek or certain portions of the Olentangy River Watersheds) requesting coverage for your discharges under the general permit. The requirements in the CGP for construction site stormwater discharges require operators to minimize erosion from construction sites and minimize the discharge of sediment and other construction site pollutants in stormwater. You should note in the SWPPP when construction activities actually commenced and modify your NOI to reflect the estimated project start date once the estimated date is known so that you properly document why inspections did not begin 7 or 14 calendar days after the effective date of permit coverage. The CGP includes requirements to protect impaired waters that receive construction site stormwater discharges. As stormwater flows over a construction site, it can pick up sediment, debris, and chemicals, and transport them to receiving waterbodies. You are considered provisionally covered under the terms and conditions of this permit immediately, and fully covered 14 calendar days after EPA notifies you that it has received a complete NOI, unless EPA notifies you that your authorization is delayed or denied. In March 2014, EPA amended the C&D rule. PDF Developing Your Stormwater Pollution Prevention Plan: A Guide for For example, if the storm event that produces 0.25 inches of rain occurs on a Saturday, the inspection would be required on Monday, the next work day. There are several situations where discrete projects that could conceivably be considered part of a larger common plan can actually be treated as separate projects for the purposes of permitting: A public body (e.g., a municipality, state, tribe, or federal agency) need not consider all their construction projects within their entire jurisdiction to be part of an overall common plan. Municipal Regional Stormwater Permit (MRP 3) - City of Oakland Perennial vegetation could include grasses, ground covers, trees, shrubs, etc. Coverage begins 14 calendar days after EPA acknowledges receipt of an NOI (electronically via the NeT system), unless EPA notifies you that your coverage has been delayed or denied. The exemption at 122.26(c)(1)(iii) does not apply to CWA 404 permits. On September 27, 2022, the Texas Commission on Environmental Quality (TCEQ) held a public stakeholder meeting to discuss the upcoming 2024 renewal of the TPDES Phase II Municipal Separate Storm Sewer System (MS4) General Permit, TXR040000. .3 The 2022 CGP becomes effective on February 17, 2022. Computer systems (including hardware and software), controls, and attendant documentation that are part of the electronic recordkeeping system are readily available for, and subject to, agency inspection. (8) "Existing Stormwater Discharge" means a discharge of regulated stormwater runoff which first occurred prior to June 1, 2002 and that is subject to the permitting requirements of 10 V.S.A. Sediment can also accumulate in rivers, lakes, and reservoirs, leading to the need for dredging or other mitigation to prevent reduced water storage or navigation capacity. You must submit your NOI at least 14 calendar days prior to commencing earth-disturbing activities. . To modify an NOI, you may submit a Change NOI form using EPAs NPDES eReporting Tool (NeT). For example, the buffer requirements would not apply if a waterfront promenade completely occupied the 50-foot buffer area. Construction stormwater permit - Washington State Department of Ecology Initiate the installation of stabilization measures immediately in any areas of exposed soil where construction activities have permanently ceased or will be temporarily inactive for 14 or more calendar days; and. PDF Stormwater Permitting for Oil- and Gas-Related Operations 9VAC25-870-830. If the EPA Regional Office gives you approval to submit a paper NOI modification, you may indicate any NOI changes on the same NOI form in Appendix J in the permit. For that reason, EPA has provided for site-specific authorization if a site intends to use cationic treatment chemicals during construction. The non-numeric effluent limits include requirements for: Yes. The seller must notify the new owner about his/her responsibilities concerning the permit, and must notify the State Water Board by . Yes. For example, if a linear construction site has only ten feet of right-of-way between the disturbed area and a stream, permit compliance can be achieved by providing a ten-foot natural buffer, or by providing a narrower buffer (e.g., five feet) and additional erosion and sediment controls (e.g., a fiber roll barrier in addition to the perimeter control), or by providing exclusively erosion and sediment controls. The controls that you use to keep the stormwater on your site so that it does not reach a water of the U.S. must be effective under any size storm. When is a CWA Section 402 (Stormwater) Permit Required for an Oil or Gas Operation? After the initial common plan construction activity is completed for a particular parcel, any subsequent development or redevelopment of that parcel would be regarded as a new common plan of development. Having a system to detect document modifications is important for final versions of documents kept for compliance purposes and does not have to include draft documents that are still undergoing changes; The electronic recordkeeping system identifies any person who creates, certifies, or modifies an electronic record; Originals of any electronic record are immediately and automatically transferred to and held at a single location by a custodian of records who is not an author, certifier, or modifier of the electronic records. Complete the installation of stabilization measures as soon as practicable, but no later than 7 calendar days after stabilization has been initiated. .3 2 .A Am I Required to Develop a SWPPP? What Is It? The sediment, turbidity, and other pollutants entrained in these stormwater discharges contribute to aquatic ecosystem degradation, increased drinking water treatment costs, and impairment of the recreational use and aesthetic value of impacted waters. With respect to when an inspection would be required for operators conducting inspections after a 0.25 inch storm event if the rain volume threshold is reached on a non-working day, it was EPAs intention that the inspection be conducted on the next work day. At least 14 calendar days before the date the transfer to the new operator will take place. As long as they still meet their obligations under the CWA, nothing in the Act precludes a state from adopting or enforcing requirements that may be more appropriate to address discharges in their state or are more stringent or extensive than those required under NPDES regulations. To provide maximum flexibility for operators, EPA developed buffer compliance alternatives in the CGP. The 2017 CGP establishes a modified approach to the stabilization deadlines, which is based on the concept of phasing construction disturbances.

For assistance, please contact the IPDES E-Permitting Support at (833) 473-3724 or IPDESE-Permitting@deq.idaho.gov. The Construction and Development Effluent Limitation Guidelines and New Source Performance Standards require construction sites to provide and maintain natural buffers around Waters of the U.S. (40 CFR 450.21(a)(6)) and minimize sediment discharges from the site (40 CFR 450.21(a)(5)), which EPA implements in the CGP in Parts 2.2.1 and 2.2.3. Read all ; Section 300. Note that the certifier cannot use an authorized representative to certify the EPA CGP NOI form. The exemption only applies to stormwater discharges from oil and gas exploration, production, processing or treatment, or transmission facilities (e.g., facilities/activities directly related to extraction or basic oil/gas processing such as fractionation plants, and not to such operations as liquified natural gas (LNG) re-gasification and ethanol plants). A sediment-related parameter is an indicator pollutant used to measure sediment pollution, such as total suspended solids (TSS) or turbidity. All new or re-issued NPDES construction stormwater permits must incorporate the C&D rule requirements, as amended. For example, if the operator is a general contractor building homes on multiple lots as part of a larger residential subdivision development, and the operator has submitted one NOI to cover all of the lots, that operator would not be able to submit an NOT until all of the lots are eligible for termination. (i.e., the buffer area) is completely occupied by preexisting development disturbances (e.g., impervious cover), EPA would consider there to be no preexisting natural buffer area on your site and would consider it infeasible to provide and maintain a natural buffer, and you would be exempt from the buffer requirements in the EPA CGP. All NPDES Stormwater Industrial permits include a table that lists the parameters that an industrial facility is required to monitor and the benchmarks associated with each parameter. Who Must Apply for a NPDES Stormwater Permit Wait until you receive the Ohio EPA approval letter stating that you are covered under the general permit. Where clearing, grading, or excavating (i.e., down to bare soils) takes place, permit coverage is required if at least one acre (separately or as part of a larger plan of development) is disturbed. For a municipality, state, federal, or other public agency: By either a principal executive officer or ranking elected official. Complete and submit as part of your application for new applicants or major amendment applications received on or after November 1, 2022 Waivers from electronic reporting may be granted based on one of the following conditions: If your operational headquarters is physically located in a geographic area (i.e., ZIP code or census tract) that is identified as under-served for broadband Internet access in the most recent report from the Federal Communications Commission; or. Industrial Stormwater Guidance | US EPA Each operator for a site must submit one NOI to cover the areas of the site that are under his/her control. These are: . For a partnership or sole proprietorship: A general partner or the proprietor, respectively. This language may need to be modified to reflect local . Share sensitive information only on official, secure websites. Do sites that drain directly to a NYC waterbody have to comply with either Chapter 19.1 or Chapter 31 requirements? Therefore, operators have the flexibility to disturb more land when necessary, but are required to stabilize faster because more land is unprotected and vulnerable to erosion and sediment transport during storm events. The runoff picks up pollutants like trash, chemicals, oils, and dirt/sediment that can harm our rivers, streams and lakes. Stormwater Program | NC DEQ Complete the application form . The operator must also submit a Notice of Intent, which provides certification that the eligibility requirements have been met and that permit requirements will be complied with. Developing a Stormwater Pollution Prevention Plan (SWPPP) Original drainage area map (prior to10/01/2001) 2. Oil and Gas Stormwater Permitting | US EPA The deadline for sites discharging to sensitive waters remains unchanged (within 7 calendar days), and the exceptions for sites in arid, semi-arid, and drought-stricken areas and for operators affected by circumstances beyond their control also remain unchanged. The 2021 Seattle Stormwater Code and Manual became effective on July 1, 2021. Additionally, if any portion of the construction activity associated with one of these facilities no longer qualifies for the oil and gas exemption, the operator must obtain construction stormwater permit coverage for all subsequent discharges of pollutants to a water of the U.S. from the site. Operators do not have to wait for other portions of the larger common plan of development or sale that they did not include in their original NOI and do not have control over (i.e. Only the interconnected parts of single project would be considered to be a common plan (e.g., a building and its associated parking lot and driveways, airport runway and associated taxiways, a building complex). Waivers are not available for any construction activity disturbing 5 or more acres, or less than 5 acres if part of a common plan of development or sale that will ultimately disturb 5 or more acres (or if designated for permit coverage by EPA). Yes, you must update your NOI when information on your original NOI has changed. The Stormwater Permitting Program: Operators covered by the permit must ensure that all activities on the site comply with the requirements of the permit. Below are EPAs recommendations with respect to electronically preparing, signing, and maintaining SWPPPs, inspection reports, and corrective action reports under the 2017 CGP. What is Stormwater? A Construction Site Operator's Guide to EPA's Stormwater Permit Program All construction sites disturbing 1 or more acres . EPA provides an example for how this calculation could be done in Attachment 3 of Appendix G in the permit (see Example 2). For example, Small Residential Lot Compliance Alternative 1 specifies that, if you retain a buffer width of 30 feet or less, you would need to provide the following: (1) a double row of perimeter controls between the disturbed portion of your site and the surface water spaced a minimum of five (5) feet apart, and (2) completion of stabilization within seven (7) calendar days of the temporary or permanent cessation of earth-disturbing activities. The fastest and easiest way to obtain permit coverage is through EPA's new online permit application . The permit is not transferable, so the responsibility to obtain permit coverage, update the Storm Water Pollution Prevention Plan (SWPPP), and comply with permit requirements becomes that of the new owner. Therefore, the 2017 CGP includes revisions that reflect the 2014 C&D rule amendments, as well as maintains the existing changes that were made to the 2012 CGP to incorporate the other portions of C&D rule requirements not affected by the 2014 amendments. Industrial Stormwater Program | California State Water Resources If operational control changes, the old operator must submit an NOT and the new operator must submit an NOI before taking over operational control. The current permit went into effect on Jan. 1, 2021, and expires on Dec. 31, 2025. EPAs CGP relies on the submission of an electronic document called a Notice of Intent (NOI) to gain coverage under the permit. Find more information on compliance information on the MS4 permit below. Complete the installation of stabilization measures as soon as practicable, but no later than 14 calendar days after stabilization has been initiated. The CGP applies to operators of construction activities that will disturb one or more acres of land, or that will disturb less than one acre but are part of a common plan of development or sale that will ultimately disturb one acre or more. Permittees are required to develop and implement a Sedimentation and Erosion Control Plan, adhere to materials handling protocols, inspect their sites and maintain records.
