ST. PAUL, Minn.—The Erosion Control Technology Council (ECTC) recently updated its guidance document for use by industry professionals. The document, A Technical Guidance Manual: Terminology, Index & Performance Testing Procedures for Rolled Erosion Control Products, can be found on ECTC’s website at , under the "Testing" category under the "Documents & Tools" section.

The document originally was developed by ECTC to aid in the understanding and use of the most recent terminology, index/physical property test methods, and performance research for rolled erosion control products (RECPs). It also was intended to assist engineers, geologists, soil scientists, landscape architects, contractors, and research facilities within the erosion control industry in the selection of RECPs. According to the ECTC, the new document continues with these efforts and includes bench scale testing information. It also contains updates to all ASTM standards to reflect the current state of practice.
