Re: 32.5 Road Gravel Pit, File No. M-2009-035, c Construction Materials Reclamation Permit Application
Package, Preliminary Adequacy Review.
Dear Mr. Azcarraga:
The Division of Reclamation, Mining and Safety has begun the review process for the above referenced 112
amendment application. The project appears to be a straight forward request to permit a construction materials
operation. A review of the application has revealed a few clarifications and issues that need to be addressed.
1. EXHIBIT C - Pre-mining and Mine Plan Maps Map (Rule 6.4.3(e)): Please provide a revised
map(s) that include corrections/clarification for the following items:
• Identify the existing type of present vegetation covering the affected lands.
• Please clearly label the permit boundary and be sure that a scale is provided on both the pre-
mining and mine plan maps.
2. EXHIBIT D - Mining Plan (Rule 6.4.4): Please provide clarification for the following items:
• Specify the estimated size of areas to be worked at any one time;
The Mine plan states that 30.25 acres will be mined for sand and gravel. The application also
states that 30.25 acres will be included in the permit area. The mine plane map shows two mine
phases, Phase 1 consists of 7.97 acres and Phase 2 consists of 22.28 acres for a total of 30.25
acres. It appears that more than 30.25 acres will be required to mine the proposed operation.
The additional required acreage will likely be needed for access roads, topsoil stockpiles,
overburden stockpiles, water settling ponds and material processing. Please describe how the
operation will only affect 30.25 acres.
• Describe any improvements necessary on existing roads and the specifications to be used in the
construction of new roads. New or improved roads must be included as part of the permitted
acreage. Describe any associated drainage and runoff conveyance structures to include
sufficient information to evaluate structure sizing;
• It is stated in the mine plan that "the mined areas behind the highwall will be backfilled using
overburden from the next mined area and imported inert fill." Please explain why the areas
