crushed aggregate emissions

AP-42 Section 11.19.2 Crushed Stone Processing and

Crushed Stone Processing . Emissions of PM, PM-10, and PM-2.5 occur from a number of operations in stone quarrying and processing. A substantial portion of these emissions consists of heavy particles that may settle out within the plant. As in other operations, crushed stone emission sources may

AP42 13.2.4 Aggregate Handling And Storage Piles

Feb 01, 2006· Worst-case emissions from storage pile areas occur under dry, windy conditions. Worst-case emissions from materials-handling operations may be calculated by substituting into the equation appropriate values for aggregate material moisture content and for anticipated wind speeds during the worst case averaging period, usually 24 hours.

RULE 1157 PM10 EMISSION REDUCTIONS FROM

The purpose of this rule is to reduce PM10 emissions from aggregate and related operations. (b) Applicability AGGREGATE OPERATIONS are defined as operations that produce sand, gravel, crushed stone, and/or quarried rocks. (2) AGGREGATE OR RELATED MATERIAL means material that is produced and/or used by the aggregate and related operations.

A cradle to gate LCA framework for emissions and energy

Jun 01, 2016· The crushed stone and the gravel and sand industries do not specifically align with the coarse and fine aggregate materials used in conventional concrete, therefore a singular aggregate emission factor was created to better represent the total amount of emitted CO 2 eq emissions from the aggregate fraction of concrete.

Sustainability of aggregates in construction ScienceDirect

Jan 01, 2016· Aggregate producers are responsible for ensuring that the noise and dust emitted from the pit or quarry do not exceed regulated levels. Carefully prepared and implemented noise and dust control plans can keep emissions within the required limits. The size and design of blasts can be modified to limit generation of noise and dust.
