   (4)   Erosion and Sediment Control Plan Requirements.
      (a)   An erosion and sediment control plan and a narrative Stormwater Pollution Prevention Plan (SWPPP) is required whenever QLP Permit coverage is required. In addition, a separate erosion and sediment control plan may be required for a Grading Permit if the Public Works Department determines that the development is so complex that soil erosion and sediment controls cannot be included in the grading plan in a clear and understandable manner or if it is determined that the site is in a special hazard area.
      (b)   The erosion and sediment control plan shall be prepared by a professional engineer registered in the state of Tennessee. This plan will be clearly identified as an "erosion and sediment control plan". A Stormwater Pollution Prevention Plan must be developed by persons meeting the requirements for SWPPP preparation as required by the Tennessee Construction General Permit that is effective at the time the stormwater pollution prevention plan is approved.
      (c)   Erosion and sediment control plans will conform to the requirements of the Tennessee Construction General Permit.
   (5)   Standards for Erosion and Sediment Control Plans. The Tennessee Erosion and Sediment Control Handbook (latest edition) has been adopted by the City of Cookeville as an approved best management practices manual. Other specifications may be used upon review and approval of the Public Works Director.
   (6)   Requirements for Erosion and Sediment Control.
      (a)   The design, installation, operation, maintenance, inspection, record keeping and reporting of construction site runoff best management practices intended for erosion prevention and sediment control and other construction related wastes or pollutants shall be performed in accordance with the requirements of the Tennessee Construction General Permit that is effective at the time the Grading Permit or the QLP Permit coverage is obtained.
      (b)   The requirements set forth in the Tennessee Construction General Permit and the Tennessee Erosion and Sediment Control Handbook may be updated and expanded at the discretion of the Director of Public Works, based on improvements in engineering, science, monitoring and local maintenance experience.
      (c)   Neighboring persons and property shall be protected from damage or loss resulting from excessive stormwater runoff, soil erosion or deposition upon private property or public right-of-way of water transported silt and debris. Adjacent property owners shall be protected from land devaluation due to exposed bare banks.
   (7)   Permitting Procedures. The following procedures for applying for either a Grading Permit or QLP Permit coverage shall apply:
      (a)   Pre-application conference. A pre-application conference with the Public Works Department is required to assure timely permit application preparation and review. This conference will be used to determine if a proposed project qualifies for exemption and to determine how technical guidelines and criteria should be applied. At this time a decision will be made as to which permit is required for the project.
      (b)   Submittal. Submission of the permit application, plans (one (1) set) and any other required submittals, i.e. drainage calculations, water quality is to be made to the Public Works Department. Plans and submittals for a Building Permit must be submitted to the Codes Department for the review by the plans examiner.
      (c)   Review. The Public Works Department will review the permit application to ensure that all information is provided in accordance with the regulations. Should the application be found to be incomplete, it will be returned to the applicant with a written request for additional information. The application will not be processed until such time as any requested information or reports are submitted.
      (d)   Permit issuance. If the work described in the permit application, including drawings and/or SWPPP, conforms to the requirements of these regulations and any other pertinent laws and ordinances, and when the fees and warranty of improvements have been paid, a Grading Permit or QLP Permit coverage will be issued. Alternately if the permit application does not meet the requirements the application will be denied and a written explanation will be provided to the applicant. The issuance of either permit will not be construed to mean approval for violation of any of the provisions of these regulations or any other law or regulation; and such permit will not be valid, except insofar as the work or use that it authorizes is lawful. The issuance of a Grading Permit shall not prevent the Director of Public Works from requiring the correction of errors or changes due to unforeseen problems in permitted plans and specifications. The Director of Public Works may require operations and project design be modified if significant problems occur which were not considered at the time the permit was issued. The issuance of a Grading Permit or QLP Permit coverage in no way implies that a building permit will be issued.
      (e)   Revisions to approved plans. Prior to or during construction, should changes be anticipated that would constitute a revision of the plans already approved by the Public Works Director, the approved plans are to be revised and resubmitted in triplicate with a letter stating why such changes are believed necessary. Approval or disapproval by the Public Works Director will be given in written form.
      (f)   Expiration. Every permit issued by the Public Works Director under provisions of these regulations shall expire by limitation and become null and void if the work authorized by such permit is not commenced within ninety (90) days from the date of issuance of the permit, provided that consecutive renewal of such permit may be granted, at no additional cost, upon written request to the Public Works Director with good cause shown. The work authorized by such permit shall not be suspended or abandoned at any time after the work is commenced and shall be carried to completion or the permit shall be void. If work is suspended or abandoned, the required warranty of improvements may be issued to correct or eliminate erosion, drainage problems, or hazardous conditions.
      (g)   Suspension or revocation. The Public Works Director shall suspend or revoke a permit issued under provisions of these regulations by giving notice in writing to the owner whenever the permit is issued in error, on the basis of incorrect information supplied or in violation of any ordinance, regulation or any of the provisions of these regulations.
   (8)   Construction Procedures.
      (a)   Permit required prior to commencing any work. A person, firm, or corporation required to obtain a Grading Permit or QLP Permit coverage in compliance with these regulations must do so prior to commencing any work pertaining to the permit. Corrective measures, including but not limited to stop work orders, penalties, and injunctions, may be taken as required to enforce the terms of this requirement.
      (b)   Posting of permit. Work requiring a Grading Permit or QLP Permit coverage shall not be commenced until the permit holder or his agent has posted the permit and SWPPP if one is required, in a conspicuous place on the front of the premises. The permit/SWPPP shall be protected from the weather and be placed to allow easy access for recording entries. The permit shall remain posted until the certificate of occupancy has been issued and/or a notice of termination has been turned into the Public Works Director on QLP Permit coverage.
      (c)   Notification of construction. After posting the permit, the permittee must first install all erosion and sediment control measures as shown on the plans. All clearing and/or earthwork are subject to inspection by the city, and should it be determined that additional erosion control measures are needed they shall be promptly acquired and installed by the permittee.
      (d)   Observation of construction. The owner shall be responsible for the ongoing observation, review and field issuance of reports in the actual earthwork. This responsibility shall include, but need not be limited to, testing, inspection and issuing field reports as to the establishment of line, grade and drainage of the project area. Civil engineering record documents shall be preserved in accordance with state law. Permittees with QLP Permit coverage are responsible for documented inspections on approved inspection forms and shall be performed in accordance with the requirements of the Tennessee Construction General Permit that is effective at the time the stormwater pollution prevention plan is approved.
      (e)   Notification of non-compliance. If the owner, his contractor or his consultants finds that the work is not being done in conformance with these regulations or the permitted plans, the discrepancies, if not corrected in a timely manner, must be reported immediately in writing to the Director of Public Works. Plans for corrective measures must be submitted to the Director of Public Works along with an appropriate schedule for completion of such corrections.
      (f)   Replacement of contractors or consultants. If the owner's contractor, civil engineer, engineering geologist or the testing agency of record, are changed during the course of the work, the owner shall replace the contractor or consultants of record with a qualified individual, and will notify the Director of Public Works in writing. Those with QLP Permit coverage are required to have the contractor listed on their QLP NOI and any change in the contractor must be noted and the new contractor must sign the QLP Permit.
      (g)   Notification of completion. Holders of a Grading Permit must notify the Director of Public Works when the project has been completed, including installation of any permanent stormwater management facilities in accordance with the final permitted plans. Those with QLP Permit coverage must complete a Notice of Termination (NOT) form provided in accordance with the requirements of the Tennessee Construction General Permit that is effective at the time the stormwater pollution prevention plan is approved. Once a NOT has been received by the Public Works Department, the department will review the NOT and inspect the site to determine if coverage under the QLP permit can be terminated or if there are deficiencies that must be corrected prior to permit termination. Any deficiencies are discovered the permittee will be notified in writing within thirty (30) days of receiving the NOT. When the site meets the termination criteria, the NOT should be re-submitted.
      (h)   Release of warranty of improvements. One (1) year following the installation of permanent vegetation, the owner may request the Public Works Department check the vegetation on site and if it is found to have seventy- five percent (75%) coverage and be in good condition the warranty of improvements will be released. If it is discovered that the vegetation is not established, the warranty of improvements must be kept by the city until such time as the vegetation is well established. Should the warranty of improvements be in the form of a letter of credit, upon receiving notice that the letter of credit needs to be renewed the owner will provide the Public Works Department with a letter of credit for an additional year.
