Upon completion of construction, the property owner is responsible for ensuring that the stormwater facilities are regularly inspected and maintained. Maintenance and inspection procedures are as follows. 1. On a quarterly basis and following significant rainfall events or snow-melts, perform the following: • Inspect catch basins, storm manholes, treatment structures, storm piping and stormwater pond for debris and accumulation of sediment. • Remove and properly dispose of any collected debris and sediment in accordance with applicable state, federal and local regulations. • Flush piping with water if necessary to remove accumulated sediment. • Bioretention areas shall be maintained per the NYSDEC Maintenance and Management Checklist included in this SWPPP. • Check all stone outfall structures for erosion and re-stone if necessary to prevent further erosion. • Inspect grassed/landscaped areas for un-vegetated areas or areas with less than 85% healthy stand of grass and reseed and mulch as necessary. Water daily if reseeded in July and August. • A record of all inspections should be kept. 2. Maintain all lawn areas by regular mowing, including the grassed slopes of the stormwater pond and any grass swales. Any eroded areas shall be regarded, seeded and mulched immediately. 116 INSPECTION AND MAINTENANCE REPORT FORMS Once installation of any required or optional erosion control device or measure has been implemented, inspections shall be performed by a Qualified Professional at least once every seven (7) calendar days. For construction sites where soil disturbance activities are on-going and the owner or operator has received authorization in accordance with Part II.C.3 of the General Permit to disturb greater than five (5) acres of soil at any one time, the qualified inspector shall conduct at least two (2) site inspections every seven (7) calendar days. The two (2) inspections shall be separated by a minimum of two (2) full calendar days. The owner and contractor shall obtain from the MS4 an approval for disturbing more than five-acres at any given time. For construction sites where active construction has been suspended, inspection frequency under the general permit can be reduced to once every 30 days, provided temporary stabilization measures have been applied to all disturbed areas. The forms found in this SWPPP shall be used by the inspectors to inventory and report the condition of each measure to assist in maintaining the erosion and sediment control measures in good working order. These report forms shall become an integral part of the SWPPP and shall be made readily accessible to governmental inspection officials, the Operator’s Engineer, and the Operator for review upon request during visits to the project site. In addition, copies of the reports shall be provided to any of these persons, upon request, via mail or facsimile transmission. Inspection and maintenance report forms are to be maintained by the permittee for five years following the final stabilization of the site. 117 OTHER RECORD-KEEPING REQUIREMENTS The Contractor shall keep the following records related to construction activities at the site: Multifamily Development 5/26/26 Page 17 of 23 Page 583 of 849
