Details of the recertification program may be found in the documents below:
NOTE: It is important for employers and industry personnel to understand that these certifications are on a very basic level and do not imply that a technician is qualified to do anything more than sample and/or test materials. That is to say, they are certified to provide data to industry experts who interpret the data and make decisions based on their level of expertise.
Standard Operating Procedure No. 1 (SOP 1)
Standard Operating Procedure No. 1 (SOP 1) "Monitoring the Quality of Coarse and Fine Aggregates," is the document that governs how Georgia's Aggregate Quality Assurance Program is administered. It clearly defines what constitutes certifiable aggregates and defines the Department's policies for accepting delivered materials.

Qualified Products Lists (QPLs) and Certification
Qualified Products Lists (QPL) 1 and 2 list all potential sources of aggregate and specify the acceptance criteria for aggregate delivered from them. Based upon internal Quality Control Programs, most sources listed on the QPL are allowed to certify the quality of their aggregates.
Certified aggregates are allowed to be delivered to the project and incorporated directly into the work without any notification to or pre-testing by the Department being required. Acceptance samples of certified aggregates are taken by the Department at a greatly reduced frequency.
The approved status of a source to certify aggregates is contingent upon their meeting the specifications, strict adherence to source specific Quality Control Programs and compliance with the policies of SOP 1. The Quality Control Programs are prepared by the Department and tailored to the specific source depending upon the nature of the deposit and plant capabilities. The sources are visited by Area Aggregate Engineers on a random but routine basis.
The quality of materials is also monitored by the continual review of test results of samples that are submitted on a regular basis to the Central DOT Laboratory by the Area Aggregate Engineer. The quality of the producer's certification data is also monitored by an Aggregate Rating System that statistically determines when a producer's data is too marginal to be accepted for certification.
Aggregates from sources that are not approved to certify their materials are approved on a stockpile basis only.
