Box 1358 Burlington, NC 27216 1103 S. Mebane St., Burlington, NC 27215 Phone (336) 222-5140 Fax (336) 222-5142 Email stormwater@ci.burlington.nc.us www.BurlingtonNC.gov/stormwater Table of Contents Introduction The National Pollutant Discharge Elimination System (NPDES) Phase II Stormwater Program is an effort to preserve, protect and improve the nation’s water resources from polluted runoff. The program requires Burlington and other municipalities to obtain a federal stormwater permit. The City of Burlington’s permit was issued July 1, 2005. A requirement of the Burlington permit was the adoption of a post construction stormwater ordinance. The ordinance follows the N.C. Division of Water Quality’s Stormwater Model Ordinance and the Best Management Practices (BMP) Design Manual, and was adopted by the Burlington City Council June 19, 2007. In August 2009, the NC General Assembly approved the Jordan Lake Nutrient Management Strategy. These rules are designed to address excessive chlorophyll a levels in the lake and are applicable to all of the Jordan Lake watershed, including the City of Burlington and its ETJ. The City of Burlington Stormwater Ordinance was revised on August 10, 2012 to incorporate the new development requirements as outlined in the rules. These may be viewed at: City of Burlington Stormwater Ordinance NCDENR BMP Design Manual The ordinance was effective August 10, 2012, and affects all new development and redevelopment of one acre or more for residential and one-half acre or more for other zonings. Additional information can be obtained by contacting the City’s stormwater manager at 336-222- 5140 or visiting the City’s Stormwater website at http://www.BurlingtonNC.gov/stormwater. Overview of the Stormwater Permitting Process at the City of Burlington The Stormwater permitting process can be separated into three phases – 1) Planning, Preliminary Design and Technical Review, 2) Final Design, Construction Drawing Review, and Permitting, and 3) Construction and Inspection. Highlights of each of these phases are presented on three flow charts that are part of this Administrative Manual. Please review the City of Burlington Stormwater Ordinance for more details. Stormwater Management System Concept Plan Technical Review Committee (TRC) Submittal The Planning, Preliminary Design, and Technical Review phase is outlined on Stormwater Flow Chart page 1 of 3 titled “Stormwater Management System Concept Plan Technical Review Committee (TRC) Submittal.” At this stage, drawings relating to stormwater facilities will most likely be shown in plan view, but should be of sufficient detail that reviewers may determine with reasonable confidence that the Stormwater Management System Concept Plan will meet the intent of the Stormwater Ordinance. The Stormwater System Concept Plan shall be submitted to the Technical Review Committee (TRC), and shall be reviewed by TRC based on the schedule published on the Planning Department’s website. Applications, application fee information and a TRC submittal and meeting schedule may be found at the Technical Review Committee website: http://burlingtonnc.gov/index.asp?NID=495 or by selecting the following links: ❑ TRC MEETING SCHEDULE AND PLAN SUBMISSION DATES ❑ TECHNICAL REVIEW COMMITTEE APPLICATION ❑ TRC PLAN SUBMISSION STANDARDS The design consultant must also submit a completed “Environmental Review Certification” form as a supplement to the TRC application. The Environmental Review Certification form is located in this Administrative manual following the Stormwater Flow Charts or at the following link. A completed Operation and Maintenance Agreement and a draft copy of the Operation and Maintenance Manual shall also be submitted at this time. The Stormwater Management System Concept Plan is only a portion of the TRC submittal. The Technical Review Committee must approve the proposed plan with respect to City ordinances and policies relating to all components of the development plan (e.g., zoning, subdivision, utility, landscape, etc) in addition to the Stormwater Management System Concept Plan before the developer may submit an application for the Stormwater Permit. Stormwater Management System Permit Process The Final Design, Construction Drawing Review, and Permitting phase is shown on Stormwater Flow Chart page 2 of 3, titled “Stormwater Management Permit Process.” At this stage, a completed Permit Application (found in this manual or at the following link), permit review fee (see this link), full construction drawings and any other information required on the “Submittal Checklist” (found in this manual, or at the following link) or deemed necessary by the designer shall be submitted to the Stormwater Manager. The person listed as financially responsible for the project shall be the same person denoted financially responsible when applying to the Engineering Department for a Land Disturbing Activity Permit (Sedimentation and Erosion Control). The completed Operation and Maintenance Agreement that was submitted as part of the TRC submittal must be executed prior to the issuance of the Stormwater Permit. An escrow account for maintenance of the structural BMPs shall also be established prior to the issuance of the Stormwater Permit. The design professional shall submit an estimate of construction costs and anticipated maintenance costs for review by the Stormwater Administrator. The funding of the escrow account by the developer shall be a minimum of 40% of the estimated construction costs of the Structural BMPs. (The owner/developer may elect to fund more than the minimum.) Per the Stormwater Ordinance the Stormwater Administrator has 60 calendar days in which to conduct the review once the application is considered complete. It is anticipated that the review process will take considerably less than the allowed time, but the review time may vary depending on workload, staffing, etc. The Stormwater Administrator will notify the designer in a timely manner (generally within one week of receipt of the application) of any missing information. The 60-day review period will not begin until missing information is received. Once all required information is received, the Stormwater Manager or a designee will review the submittal. The reviewer may request additional information or plan revision, issue a Notification of Disapproval, or approve the plans (with or without conditions) and issue a Stormwater Permit. If a Notification of Disapproval is issued, the applicant may resubmit a revised plan within 30 calendar days of disapproval without paying an additional permit review fee. An additional review fee shall accompany any re-submittal after the first re-submittal. Within 30 calendar days re-submitted plans will be either approved (with or without conditions) or disapproved. Requirements for a Performance Security Bond , 125% of estimated construction costs, will be addressed in the approval letter accompanying the Stormwater Permit. Stormwater Management Construction and Final Review Process The Construction and Inspection Phase is outlined on Stormwater Flow Chart page 3 of 3, titled “ Stormwater Management Construction and Final Review Process.” Once the Stormwater Permit is issued, construction may begin, provided all other environmental permits have been obtained, or are in the process of being obtained, and all requirements of the City of Burlington Engineering Department have been satisfied. Contact the Engineering Department at 336-222- 5050 regarding the status of other permits. During construction, the financially responsible party is responsible for inspection of sediment and erosion control measures weekly and after every rain event of at least one-half inch per the Division of Water Quality’s General Stormwater Permit No. NCG010000 issued as part of the City’s Land Disturbing Activity Permit. City staff may conduct periodic inspections of Stormwater BMPs, however the designer is ultimately responsible to certify that any structural BMPs meet the requirements of the ordinance and Stormwater Permit. All structural BMPs should be substantially complete and the designer should submit certification and as-built drawings prior to recording of plats and prior to the time a Certificate of Occupancy is needed. At the discretion of the Stormwater Manager, a performance security for the completion of structural BMPs or issuance of As-Built drawings will allow a plat to be recorded or enable Building Inspections to issue a Certificate of Occupancy. Forms for BMP certification and As-Built submittals are included in this Administrative Manual. The Stormwater Administrator or his designee will perform a final inspection of each stormwater BMP. Prior to the closeout of the Stormwater permit and release of any performance securities related to BMP installation or As-Built drawings, the Stormwater Administrator must receive and approve the As-Built drawings, the site must be in compliance with the City’s Sedimentation and Erosion Control Ordinance, and the project must pass the final stormwater inspection.
