Copies of SWPPP documents transmitted to the Engineer under the requirements of this specification are informational and do not relieve the Contractor’s responsibility to maintain complete records as required by the CGP and this specification. Keep the SWPPP, HMCP and SPCC Plan at the on- site project office. If there is not an on- site project office, keep the documents at a locally available location that meets CGP requirements and is approved by the Engineer. Records may be moved to another office for record r etention after the eNOTs are filed. Records may be moved to another office during winter shutdown. Update on- site postings if records are relocated during winter shutdown. Provide the Department with copies of all Records. Retain Records and a copy of the SWPPP, for at least three years after the date of eNOT. If EPA or DEC inspects the project, issues a Notice of Violation (NOV), or begins investigation for a potential NOV before the retention period expires, retain the SWPPP and all Records related to the SWPPP and CGP until at least three years after EPA and/or DEC has determined all issues related to the investigation are settled. The SWPPP and related documents must be made available for review and copy, to the Department and other regulatory agenci es that request them. See CGP Parts 5.10, 6.6 and 9.5. 641-3.03 SWPPP INSPE CTIONS, AMENDMENTS, REPORTS, AND LOGS.

b.The CGP. Provide a copy of the completed, unsigned Inspection Report to the Engineer by the end of the next business day following the inspection. The Superintendent must review, correct errors, and sign and certify the Inspection Report, within three days of the date of Inspection. The Engineer may coordinate with the Superintendent to review and correct any errors or omissions bef ore the Superintendent signs the report. Corrections are limited to adding missing information or correcting entries to match field notes and conditions present at the time the Inspection was performed. Deliver the signed and certified Inspection Report to the Engineer on the same day the Superintendent signs it. The Engineer will sign and certify the Inspection Report and will return the original to the Contractor within three working days. The Engineer may make corrections after the Superintendent has s igned and certified the Inspection Report. The Engineer will initial and date each correction. If the Engineer makes corrections, the Superintendent must recertify the Inspection Report by entering a new signature and date in the white space below the original signature and date lines. Send a copy of the recertified Inspection Report to the Engineer on the day it is recertified. If subsequent corrections to the certified Inspection Report are needed, document the corrections in an amendment memo that addres ses only the omitted or erroneous portions of the original Inspection Report. The Superintendent and the Engineer must both sign and certify the amendment memo. The issuance of an amendment memo does not relieve the Contractor of liquidated damages that ma y have been incurred as a result of the error on the original certified inspection report.
3.Inspection before Seasonal Suspension of Work. Conduct an Inspection before seasonal suspension of work to confirm BMPs are installed and functioning according to the requirements of the SWPPP and CGP.
4.Reduced Inspection Frequencies. Conduct Inspections according to the inspection schedule indicated in the approved SWPPP.
