(If you are not the owner/developer or other responsible person, please take this opportunity to correct this error as soon as possible; otherwise,you will be considered responsible.) Although you will probably contract someone (a general contractor,grading contractor,subcontractor,etc.)to implement and maintain the erosion control plan, it is your responsibility, according to the Orange County Unified Development Ordinance, to see that the requirements of the Ordinance and approved plan are achieved. It is also your responsibility to ensure the approved plan is successful in containing sediment on-site and that all permanent erosion control measures are successful. If these responsibilities are not fulfilled and enforcement and/or legal actions are taken,it will be against Kiewit Infrastructure South Co.,not the grading contractor or other contractor,unless they are the same person or firm. Erosion Control personnel will cooperate with you and your designer and contractor to implement the approved plan and meet the Ordinance requirements. To accomplish this, both you and your agents must take the initiative in contacts with Erosion Control personnel. However, this interaction must not be interpreted as relieving you of any responsibilities and transferring it to the contractor or Erosion Control personnel. Neither should it be construed that Erosion Control personnel are acting as liaison between you and your designer, contractors, or other agents. If problems arise,Erosion Control personnel will suggest solutions;however,these are only suggestions,since Erosion Control personnel will not act as your engineer. If necessary, you must employ an engineer or architect to design a solution. We will continue to work with you,your contractor,and designer,and we will contact personnel at the site whenever possible to keep the site in compliance (so long as all of you are responsive). If this approach fails,and you do not take the initiative in responding to requests for compliance, you will be given written notices of violation and enforcement action will be taken should you fail to respond by the specified deadlines. It is hoped, and is our commitment, that the first approach to inspections and compliance will be successful and that a good working relationship can be established and maintained. S:\5_Erosion Control and Water Quality\Erosion Control and Water Quality\Jobs by Year New Work 24\Mebane\Kiewit Infrastructure Maintenance Facilty-Mebane\Kiewit Infrastructure Maintenance Facilty-Mebane ROA Document.docx 2 Requirements of Approval Revised 04/17/24 In undertaking this land-disturbing activity,be aware of and observe the following requirements of the Ordinance. • PRIORITIES: Erosion and sediment control must be given equal,or greater priority with grading,construction,and other efforts to develop the site. At certain times (for example, during initial construction and when repairs and maintenance are required) erosion and sediment control will require more effort to ensure success. • EXPIRATION: Erosion control plan approval expires if work does not begin within 3 years of the date of this letter. The land-disturbing permit expires with the plan approval or two years after work begins. • THE WEATHER: Assume that this site will get at least one 6-hour, 10-year storm event (0.67 inches/hour for 6 hours) and be prepared to handle the resulting runoff and control the erosion it will cause on the site. If your site is located within the Neuse River Basin, then erosion control measures are designed to withstand the 25-year storm. • INITIATIVE: Kiewit Infrastructure South Co. must take the initiative in implementing the erosion control plan. This includes seeing that the construction sequence is followed, inspecting the installed devices, performing maintenance, and installing additional devices when necessary.Do not wait for Erosion Control personnel to discover problems; their function is not to act as your construction inspector but to spot-check the site for compliance with the approved plan. When Erosion Control personnel discover problems and there has been no initiative on your part to make corrections,you will be expected to make corrections immediately,usually within one or two days. • OTHER APPROVALS AND PERMITS: This project must comply with all local, State, and Federal environmental laws. You must have all necessary applicable approvals (i.e., zoning compliance, Department of Transportation, US Army Corps of Engineers, NC Division of Water Resources,sewer,and water,etc.) required to begin this project so that work can continue uninterrupted to completion and there are no delays that will increase erosion and sediment generation. If these approvals are not obtained and work is suspended while waiting for them,the site will have to be stabilized until work resumes. If a Land-disturbing permit has not been obtained, it is your responsibility to ensure that it is purchased before work begins. • PROPERTY LINES, CLEARING LIMITS, ETC.: Kiewit Infrastructure South Co. is responsible for determining where the property lines and clearing limits are, and for staying within those boundaries. You are also responsible for locating, and protecting such things as setbacks, water quality buffers, absorption field sites, flood plains, protected wetlands,undisturbed areas,trees to be saved, etc. • PERFORMANCE: The Ordinance is performance oriented. If it is determined that sediment damage (sediment lost off site or into streams, water bodies, or buffers) is occurring despite proper implementation and maintenance of the approved plan, it is S:\5_Erosion Control and Water Quality\Erosion Control and Water Quality\Jobs by Year New Work 24\Mebane\Kiewit Infrastructure Maintenance Facilty-Mebane\Kiewit Infrastructure Maintenance Facilty-Mebane ROA Document.docx 3 Requirements of Approval Revised 04/17/24 your responsibility to provide additional sediment trapping and/or erosion control measures.Although the plan has been carefully reviewed,unexpected difficulties may be inevitable, and you must resolve them. • RESTORATION OF AREAS DAMAGED BY SEDIMENT: You will be required to restore waters and land affected if you fail to prevent sediment damage resulting from this activity. This is in addition to any other penalty or injunctive relief. • CHANGES TO THE PLANS OR IN OWNERSHIP: If significant changes are required to the approved plan, then you must have your designer make revisions and submit copies to the Division upon request. If the site plan is revised in any way that affects erosion and sediment control,you must inform us and submit revised plans.If ownership of this project changes and responsibility is transferred to another person,you or the new owner must inform us in writing with pertinent information such as contact name, address,telephone,and fax numbers.Otherwise,Kiewit Infrastructure South Co.will be considered responsible. If you did not supply this office with the names and addresses of all members of your partnership you are responsible for supplying them with copies of this letter and any other correspondence from this office related to this project."For land- disturbing activities on a single-family residential lot involving new construction with land disturbance of less than one acre where the builder or developer is the owner of the lot being developed and the person financially responsible for the land-disturbing activity,the financial responsibility for land-disturbing activity on that lot transfers to the new owner upon the builder's or developer's conveyance of the lot to the new owner, recording of the deed in the office of the register of deeds, and notification to the office or local program that approved the erosion control plan." • COMPLETION OF DISTURBANCE IN AS SHORT A TIME AS POSSIBLE: Sediment- trapping devices are not 100% effective in removing soil particles from runoff. Therefore, the Ordinance requires that all land-disturbing activities be planned and conducted to limit exposure to the shortest feasible time. To accomplish this requirement construction must be continuous and uninterrupted until completion and permanent stabilization. If construction is interrupted or delayed or the project is abandoned, the site must be stabilized with adequate ground cover. • PROVIDE YOUR CONTRACTORS WITH A COPY OF THE APPROVED PLAN: Make sure your contractor has a copy of the approved erosion control plan, has considered it in their bid,and is prepared to proactively implement the plan. If phases of the plan will be conducted by different subcontractors, Kiewit Infrastructure South Co. must ensure that their efforts are coordinated so that the approved plan is followed. For example:if the clearing and installation of the sediment trapping devices will be done by different contractors, the clearing must not get ahead of construction of the devices. As S:\5_Erosion Control and Water Quality\Erosion Control and Water Quality\Jobs by Year New Work 24\Mebane\Kiewit Infrastructure Maintenance Facilty-Mebane\Kiewit Infrastructure Maintenance Facilty-Mebane ROA Document.docx 4 Requirements of Approval Revised 04/17/24 stated in the approved plan,the initial clearing must be limited to only that area necessary to gain access to and install the erosion and sediment control devices. • COORDINATION BETWEEN CONTRACTORS AND SUBCONTRACTORS: You must ensure that sediment and erosion control is coordinated during timbering,clearing, grading, and construction so that controls and devices are maintained and not removed or damaged. If this site is subject to NCG010000, you must adhere to all applicable requirements of that NPDES permit. More on NCG010000 requirements are mentioned below. • KEEP A COPY OF THE APPROVED PLAN ON THE SITE: The plan must be available to the contractor and inspection personnel. Failure to do so is a violation. • DISPOSAL OF CLEARING AND DEMOLITION DEBRIS AND CONSTRUCTION WASTE: All debris and waste resulting from development of the site (stumps, brush, demolished structures, construction waste, etc.) must be properly disposed of in accordance with local and State regulations. Open burning of trees, limbs, stumps, and construction debris is prohibited. Concrete, stumps and other clearing debris and construction waste must be carried to appropriately permitted landfills. • SITE INSPECTIONS: The Ordinance authorizes Erosion Control personnel to enter the site for the purpose of investigation and inspection. Erosion Control personnel will periodically inspect the site to determine if the approved plan is being implemented and if it is successful. If problems or violations are found, the Erosion Control personnel will attempt to contact site personnel to discuss with them and arrange corrections within a specified time.Also,a written site inspection report will be left with site personnel,in the mailbox on-site, or transmitted in another manner. If you, or your contractor, have questions about the inspection report,contact the Erosion Control personnel immediately -do not wait until the deadline to start asking questions. • COMMUNICATIONS: In addition to leaving inspection reports on-site, a copy will be mailed and/or faxed to Kiewit Infrastructure South Co..As the entity responsible for the land-disturbing activity,you should ensure compliance with the approved erosion control plan and see that your contractor corrects violations by the given deadline. Erosion Control personnel are generally in their offices and available by phone between 8:00 and 9:00 a.m.and 4:30 and 5:00 p.m. and have mobile phones as well.Feel free to contact them with any questions or concerns. • PERSONNEL, EQUIPMENT, AND MATERIALS MUST BE AVAILABLE FOR MAINTENANCE AND REPAIRS AT ALL TIMES: Maintenance is a critical element of the erosion control plan needed to ensure that devices continue to operate effectively.You must be prepared to work on the devices when the need arises. In order to do this, you may consider stockpiling certain materials such as stone, sediment fence and wire, etc. S:\5_Erosion Control and Water Quality\Erosion Control and Water Quality\Jobs by Year New Work 24\Mebane\Kiewit Infrastructure Maintenance Facilty-Mebane\Kiewit Infrastructure Maintenance Facilty-Mebane ROA Document.docx 5 Requirements of Approval Revised 04/17/24 • PREPARING FOR WORK: Before beginning the project, be certain that all necessary materials, such as skimmers, riser structures, pipes, etc., are available and ready for delivery or already on site. • ENFORCEMENT ACTIONS: If there is inadequate response to a verbal request or Notice of Violation, or you fail to properly implement the approved plan, enforcement action will be taken against the Kiewit Infrastructure South Co. to bring the site into compliance.Actions may include: Stop Work Orders: All work not directly related to erosion and sediment control and bringing the site into compliance, including building construction, must cease until the site is brought into compliance. Revocation of the Land-disturbing Permit: All work not directly related to erosion and sediment control and bringing the site into compliance, including building and home construction, must cease until the site is brought into compliance and another permit is issued. Fines: Up to $5000 per day may be assessed. Fines are the responsibility of Kiewit Infrastructure South Co.,not your contractor. Injunctive Relief: Legal action will be initiated in Superior Court to restrain the violation and bring the site into compliance. • STABILIZATION: Disturbed areas must be stabilized within 7 or 14 calendar days of termination / completion of any phase of grading per the following guidelines by a temporary/ permanent ground cover sufficient to restrain erosion. Perimeter dikes, swales, ditches,and slopes-7 days High Quality Water Zones- 7 days Slopes 2:1 or steeper- 7 days Slopes between 2:1 and 3:1 greater than 10' in length-7 days Slopes between 2:1 and 3:1 less than 10' in length- 14 days Slopes between 3:1 and 4:1 less than 50' in length- 14 days Slopes between 3:1 and 4:1 greater than 50' in length-7 days Slopes flatter than 4:1 -14 days If grading is not suspended more than the specified time period, the disturbed areas do not have to be stabilized until final grade is reached. However, if work is delayed or suspended for more than the specified time period and you are given a written notice to stabilize it,grading the area again does not allow you to disregard the notice. If an area is to be worked again, it must be graded and stabilized by the given deadline. When construction is completed,all disturbed areas must have a permanent,stabilizing ground cover applied within the specified time period. S:\5_Erosion Control and Water Quality\Erosion Control and Water Quality\Jobs by Year\New Work 24\Mebane\Kiewit Infrastructure Maintenance Facilty-Mebane\Kiewit Infrastructure Maintenance Facilty-Mebane ROA Document.docx 6 Requirements of Approval Revised 04/17/24 The intent of this requirement is to limit erosion by completing the disturbance and stabilizing disturbed areas in as short a time as possible. To avoid stabilizing the same area several times,schedule work so that grading and other construction are coordinated. When a particular area is finished,permanently stabilize it immediately instead of waiting until the end of the project to stabilize the entire site at once. • SUCCESS OF PERMANENT MEASURES: These measures (vegetation, other types of stabilization, channel linings, energy dissipaters, etc.) must be successful in restraining erosion. For example: If an annual plant (such as annual ryegrass) is used instead of a perennial for permanent stabilization, it is the responsibility of the owner to reseed and establish a permanent vegetative cover when the annual fails after one season. If vegetation in a ditch or channel fails to survive and establish a permanent cover so that erosion is restrained, then some other type of lining, such as matting or stone, must be provided by the owner. • MAINTENANCE OF PERMANENT MEASURES: Maintenance is the responsibility of the owner except those measures in a street or utility right-of-way accepted by a government agency. • APPEALS: You have the right to appeal the following: disapproval of the erosion control plan; modifications to the erosion control plan; any requirements of approval; and enforcement actions. Procedures are outlined in Section 2.26 of the Ordinance. Hearings are conducted by the North Carolina Office of Administrative Hearings. • NCG010000: As of April 1, 2019, all new construction activities are required to complete and submit an electronic Notice of Intent (NOI)form requesting a Certificate of Coverage (COC) under the NCG010000 Construction Stormwater General Permit.This form MUST be submitted prior to the commencement of any land disturbing activity on the above- named project. The NOI form may be accessed at deq.nc.gov/NCG01. Please direct questions about the NOI form to Paul Clark at Paul.clark@ncdenr.gov. After you submit a complete and correct NOI Form, a COC will be emailed to you within three business days. Initially, DEMLR will not charge a fee for coverage under the NCG01 permit. However, on or after May 1, 2019, a $120 fee will be charged annually. This fee is to be sent to the DEMLR Stormwater Central Office staff in Raleigh. Title 15A NCAC 4B .0118(a) and the NCG01 permit require that the following documentation be kept on file at the job site: 1. The approved E&SC plan as well as any approved deviation. 2. The NCG01 permit and the COC, once it is received. 3. Records of inspections made during the previous 30 days.
