Public comments for: Use of Ballast and Aggregate in Solar Electric Generating Systems


The rule changes as stated seem overly restricted for PV systems that are ground mounted in particular. There should be options allowed for the use of mounting systems using freeze/thaw resistant ballast, or properly weather coated ballast, when these systems provide clips or other means of securing ballast from sliding in the racks. Any racking method used in applications over 100 ft. height should require certification of both ballast and racking systems. Respectfully submitted, Lloyd Hoffstatter, M.S.
