STORM WATER POLLUTION PREVENTION SITE

INSPECTION CHECKLIST

DATE:

Construction Site Name and Contractor:

Evaluated by:

Part III. Storm Water Pollution Prevention Plans (SWP3)

Storm water pollution prevention plans (SWP3) must be prepared to address discharges authorized under Parts II.E.2.and II.E.3. of the TCEQ Construction Storm Water Permit that will reach Waters of the United States, including discharges to MS4s (Sheppard AFB) that drain to

Waters of the United States, to identify and address potential sources of pollution that are reasonably expected to affect the quality of discharges from the construction site, including off-site material storage areas, overburden and stockpiles of dirt, borrow areas, equipment staging areas, vehicle repair areas, fueling areas, etc., used solely by the permitted project. The SWP3 must describe the implementation of practices that will be used to minimize to the extent practicable the discharge of pollutants in storm water associated with construction activity and non-storm water discharges described in Part II.A.3., in compliance with the terms and conditions of this permit. It is the responsibility of each operator to ensure compliance with the terms and conditions of this general permit in the areas of the construction site where that operator has control over construction plans and specifications or day-to-day operations.

47. A sedimentation basin is required, where feasible, for a common drainage location that serves an area with ten (10) or more acres disturbed at one time. A sedimentation basin maybe temporary or permanent, and must provide sufficient storage to contain a calculated volume of runoff from a 2- year, 24-hour storm from each disturbed acre drained. When calculating the volume of runoff from a 2-year, 24-hour storm event, it is not required to include the flows from offsite areas and flow from onsite areas that are either undisturbed or have already undergone permanent stabilization, if these flows are diverted around both the disturbed areas of the site and the sediment basin. Are these capacity calculations included in the SWP3? Yes No NA

(Page 31, Section F.2(c)(i)(A)(1))

48. Where rainfall data is not available or a calculation cannot be performed, the sedimentation basin must provide at least 3,600 cubic feet of storage per acre drained until final stabilization of the site. Has this information been calculated? Yes No

NA (Page 31, Section F.2(c)(i)(A)(2))

49. If a sedimentation basin is not feasible, then the permittee shall provide equivalent control measures until final stabilization of the site. In determining whether installing a sediment basin is feasible, the permittee may consider factors such as site soils, slope, available area, public safety, precipitation patterns, site geometry, site vegetation, infiltration capacity, geotechnical factors, depth to groundwater, and other similar considerations. The permittee shall document the reason that the sediment basins are not feasible, and shall utilize equivalent control measures, which may include a series of smaller sediment basins. Has this been accomplished? Yes No NA

(Page 31, Section F.2(c)(i)(A)(3))

50. Perimeter Controls: At a minimum, silt fences, vegetative buffer strips, or equivalent sediment controls are required for all down slope boundaries of the construction area, and for those side slope boundaries deemed appropriate as dictated by individual site conditions. Is this information included in the SWP3? Yes No (Page

31, Section F.2(c)(i)(B))

Controls for Sites with Drainage Areas Less than Ten Acres:

51. Sediment traps and sediment basins may be used to control solids in storm water runoff for drainage locations serving less than ten (10) acres. At a minimum, silt fences, vegetative buffer strips, or equivalent sediment controls are required for all down slope boundaries of the construction area, and for those side slope boundaries deemed appropriate as dictated by individual site conditions. Are these described in the SWP3?

Yes No (Page 31, Section F.2(c)(ii)(A))

52. Alternatively, a sediment basin that provides storage for a calculated volume of runoff from a 2-year, 24-hour storm from each disturbed acre drained may be utilized. Where rainfall data is not available or a calculation cannot be performed, a temporary or permanent sediment basin providing 3,600 cubic feet of storage per acre drained may be provided. If a calculation is performed, then the calculation shall be included in the

SWP3. Is this information included in the SWP3? Yes No

NA (Page 31, Section F.2(c)(ii)(B))

The SWP3 Must Include A Description of Permanent Storm Water Controls

53. A description of any measures that will be installed during the construction process to control pollutants in storm water discharges that may occur after construction operations have been completed must be included in the SWP3. Permittees are only responsible for the installation and maintenance of storm water management measures prior to final stabilization of the site or prior to submission of an NOT. Are any permanent storm water controls part of this project? Yes No Are they included in this

SWP3? Yes No NA (Page 32, Section F.3)

Other Required Controls and BMPs (Section F.4)

54. Permittees shall minimize, to the extent practicable, the off-site vehicle tracking of sediments and the generation of dust. Does the SWP3 include a description of controls utilized to accomplish this requirement? Yes No (Page 32, Section

F.4(a))

55. Does the SWP3 include a description of construction and waste materials expected to be stored on-site and a description of controls to minimize pollutants from these materials?

Yes No (Page 32, Section F.4(b))

56. Does the SWP3 include a description of potential pollutant sources from areas other than construction (such as storm water discharges from dedicated asphalt plants and dedicated concrete batch plants), and a description of controls and measures that will be implemented at those sites to minimize pollutant discharges? Yes No

NA (Page 32, Section F.4(c))

57. Does the SWP3 require the Permittee to place velocity dissipation devices at discharge locations and along the length of any outfall channel (i.e., runoff conveyance) to provide a non-erosive flow velocity from the structure to a water course, so that the natural physical and biological characteristics and functions are maintained and protected?

Yes No NA (Page 32, Section F.4(d))

58. Does the SWP3 require the Permittee to design and utilize appropriate controls to minimize the offsite transport of suspended sediments and other pollutants if it is necessary to pump or channel standing water from the site? Yes No

NA (Page 32, Section F.4(e))

Documentation of Compliance with Approved State and Local Plans

59. Is the SWP3 consistent with requirements specified in applicable sediment and erosion site plans or site permits, or storm water management site plans or site permits approved by federal, state, or local officials (such as the Sheppard MS4)? Yes No

NA (Page 32, Section F.5(a))

60. Does the SWP3 identify and ensure the implementation of appropriate pollution prevention measures for all eligible non-storm water components of the discharge, as listed in Part II.A.3. of this permit? Yes No NA (Page 32, Section F.8)

61. Does the SWP3 identify that the SWP3 will be updated as necessary to remain consistent with any changes applicable to protecting surface water resources in sediment erosion site plans or site permits, or storm water management site plans or site permits approved by state or local official for which the permittee receives written notices?

Yes No (Page 32, Section F.5(b )and Page 35 Section F.7(d))

62. Does the SWP3 identify when the permittee shall perform maintenance to maintain the protective measures identified in the SWP3? Yes No (Page 32, Section

F.6(a))

63. Does the SWP3 identify when inspections will be conducted? Yes No (Page

32, Section F.7(a)(b)(c)(e))
