3 AASHTO s National Transportation Product Evaluation Program (NTPEP) Report Summary Evaluation Program for Plastic Pipe Facilities Producing HDPE Plastic Pipe Summary Report For Advanced Drainage Systems/Hancor: Winter Garden, Florida Introduction The National Transportation Product Evaluation Program (NTPEP) is a program under the sponsorship of the American Association of State Highway and Transportation Officials (AASHTO). The NTPEP Evaluation Program for HDPE Plastic Pipe Facilities Producing HDPE Plastic Pipe provides a comprehensive review of the production and testing of plastic pipe and of the quality management system. The evaluation starts with a desktop review of the facility s quality manual and concludes with an on-site review of the facility s processes and their quality management system documentation. The desktop review and the on-site review were conducted by Lead Auditor Katheryn Malusky (AASHTO) / Evan Rothblatt (AASHTO) / Dan Stegmaier (AASHTO) / Pete Spellerberg (AASHTO). ADS/Hancor was represented by Jason Richards (Plant Manager), Sam Shadowen (Quality Assurance Manager), Joe Richardson (Quality Assurance Manager Perry, GA), Robert Slicker (Director of Quality Assurance), and Terry McElfresh (Quality Assurance Manager) during the on-site audit which was completed on Thursday, February 28, The evaluation findings follow. Deviations from program requirements are noted in red. Testing Personnel (Section 1) The following personnel were approved to run quality control testing at the plant: Standard Specifications (Section 3) The plant had current versions of all applicable AASHTO and ASTM standards.
