completed by the Resident Engineer and kept with the SWPPP on the project, along with being provided to the Contractor for public posting.

NOTE:

A permit number is issued for each Medium and Large Construction

Projects requiring an NPDES permit (the tracking number). This permit number will be forwarded to the Resident Engineer upon receipt by the Construction Division. A database of all ADEQ Storm Water Runoff (NPDES) Permits is available on the Construction Page of the AHTD Employee’s Network. This web page is accessed by

entering “ahtdnet” in the Internet Explorer address line.

NOTE:

The Contractor is limited under Section 110.06(d) of the Specifications to

a maximum of 25 acres of disturbed soil on the right of way. The Resident Engineer has the authority to increase or decrease the limitation on surface area of disturbed land based on the Contractor’s capability to effectively control erosion and sedimentation on these disturbed areas. If the Contractor wishes to disturb a larger area in order to effectively carry out his operation and/or is not effectively controlling sediment from the project, the Resident Engineer should utilize this Section of the Standard Specifications to enforce implementation and maintenance of erosion and sediment control devices before

allowing the Contractor to perform further work..

(c) Inspection and Reporting. An inspection of the in-place temporary erosion control devices on each project is required a minimum of every 14 days and within 24 hours after the end of any ½” or more rainfall. This inspection should focus on the condition of existing erosion control measures, the effectiveness of the measures in place, evaluation of the status of storm water runoff from the site, and the need for additional temporary and/or permanent erosion control measures. If the storm water runoff leaving the site is carrying sediment, it is the Resident Engineer’s responsibility to alter the SWPPP to implement more effective erosion and sediment control measures. The results of the inspection are documented on the Storm Water Pollution Prevention Plan Inspection Report (Figure 110-2), which is signed by the Inspector and the Resident

Engineer.
