MINE or MINE SITE. See EXTRACTIVE OPERATION/MINE.
MINERAL RESOURCES. Rock, gravel, sand and metallic and non-metallic substances of commercial value.

NON-CONFORMING MINING OPERATIONS. Existing mines which do not meet the standards of this chapter or mining standards of Ch. 162 of this code of ordinances.
PARTICULATE MATTER. Material, except water, which exists at standard conditions in a finely divided form as a liquid or solid as measured by an applicable reference method, or an equivalent or alternative method or as amended in Minn. Rules part 7005.0100, subpart 31.
PM 2.5. Finely divided solid or liquid material, with an aerodynamic diameter less than or equal to a nominal two and one-half micrometers as measured by an applicable reference method, or an equivalent or alternative method or as amended in Minn. Rules part 7005.0100, subpart 30a.
PM 10. Finely divided solid or liquid material, with an aerodynamic diameter less than or equal to a nominal ten micrometers as measured by an applicable reference method, or an equivalent or alternative method or as amended in Minn. Rules part 7005.0100, subpart 30b.
PROCESSING. The sorting, washing, crushing and/or screening of extracted material to construction grade sand, gravel or stone product.
RECLAMATION. To renew land to a self-sustaining, long-term use that is compatible with pre- mining situations and/or the city’s Comprehensive Land Use Plan.
REFERENCE METHOD or METHOD.
(1) Used in the context of performance test measurements. The procedures for performance tests in 40 C.F.R. part 60, app. A, as amended; part 61, app. B, as amended; and part 51, app. M, as amended, or as amended in Minn. Rules part 7005.0100, subpart 35c.
(2) Used in the context of measuring ambient air. A method of sampling and analyzing the ambient air for an air pollutant that is specified as a reference method in an appendix to 40 C.F.R. § 50.1 in accordance with part 53 of the same chapter; it does not include a method for which a reference method designation has been cancelled in accordance with § 53.11 of the chapter and which is incorporated by reference Minn. Rules part 7009.0050.
SCC CODE.
(1) Source classification codes are an EPA classification system.
(2) Each SCC represents a unique source category-specific process or function that emits an air pollutant. The SCCs are used as a primary identifying data element in EPA’s WebFIRE, the National Emissions Inventory (NEI) and other EPA databases. The SCCs are also used by many regional, state, local and tribal agency emissions data systems.
(3) Point source emissions use eight digit codes.
SIC CODE. The Standard Industrial Classification is a system for classifying industries by a four-digit code used by many departments of the U.S. Government, including OSHA.
SOIL EROSION AND SEDIMENT CONTROL PLAN. A document that illustrates, how the site will be designed to prevent or minimize soil erosion on a parcel of land and off-site sediment damages.
