Overview of Construction Site Compliance Evaluation Legal entry into construction sites Pre-inspection opening conference Review of onsite documentation Construction site inspection procedures Post inspection closing conference

Overview of Field Monitoring at Construction Sites Overview of field monitoring techniques that inspectors may need to perform in order to confirm compliance or document exceedances of NALs or violations of NELs The calibration and use of field equipment and sampling techniques are presented. The inspector should also be familiar with proper selection and location of representative sampling locations

Overview of Compliance Inspection Reports Provides guidance in writing inspection reports and providing sufficient documentation for enforcement actions Discusses when re-inspection and additional actions may be necessary after the initial site inspection

Overview of Compliance Inspection Data Management Outlines the inspector’s use of the Storm water Multi Application and Report Tracking System (SMARTS)

Overview of Compliance Enforcement Activities Provides the inspector with guidance on enforcement of the provisions in the CGP
