As you have probably noticed, the DMG Application Forms (i. e. 112 Application, Question
13.2) ask for a listing of "any designated chemicals or acid-producing materials to be used or
stored within" the permit area. As an example of the type of response our applications have
provided in the past, a current draft 112 permit lists "diesel fuel, grease, hydraulic fluids,
concrete additives, cement."
None of the materials in the above list is within the intended scope of the question -none of
them need to be listed. I clarified the requirements of this question with Allen Sorenson today.
Apparently the "designated chemicals' question and language was borrowed from the DMG
hard rock (as opposed to construction materials) mining application and is intended to include
chemicals of a "hazardous materials" nature (Sorenson specifically mentioned phosphorus
pentachloride and cyanide, and generally said the question refers to corrosives and toxic
chemicals). For a sand and gravel operation such hazardous materials would, according to
Sorenson, be very unusual.
For future reference, Question 13.2 (and equivalent questions on 110 and 111 applications)
does not require listing of chemicals typically associated with sand and gravel processing or
concrete and asphalt production. Sorenson specifically listed cement, lime, petroleum
products and lubricants as being neither "designated" nor "acid-producing" for the purposes of
a construction materials permit.
