1	MCAQMD Regulation 1 Amendments Grading Public Workshops March, 2006
2	Purpose and need Dust related to construction and grading are the fourth largest source of Particulate Matter in the District. The public is being negatively impacted by dust emitted in violation of existing rules Goal is to replace reactive complaint driven process with proactive permit driven process.
3	Existing District Grading Regulations All Grading activities (except for agriculture) are subject to District Regulation 1, Rule 430. Rule 430 does not require permits, but activities must comply with it’s requirements. The District frequently warns and issues citations for failure to comply with Rule 430.
4	Rule 430 Requirements “The following airborne dust control measures shall be required during all construction operations, the grading of roads, or the clearing of land” 1.) Soil shall be watered 2.) Posted speed limit of 10 MPH or less 3.) All track-out shall be removed promptly 4.) Stockpiles must be treated to reduce dust 5.) No activities during high winds 6.) Project site secured during non-work hours 7.) Operator shall keep a log of dust control measures
5	Rule 430 Enforcement Typically the District is unaware of a large grading project until it begins to receive complaints and the public is already being affected. The District then contacts the operator and may issue a Notice of Violation if Rule 430 is not being followed. This is a REACTIVE, not a pro-active, process. The public is negatively impacted before the problem is solved.
6	Proposed Change For larger construction activities the applicant would be required to receive a permit from the District prior to starting operations. No other changes are proposed and the regulatory requirements would remain the same.
7	Why a permit? Currently the applicants are largely unaware of the Rule 430 requirements. A permit for large operations will serve as an opportunity for education and as a pre-project reminder that proper dust control is important. The Goal is to create a PRO-ACTIVE process in which the problem is solved before the public is negatively impacted.
8	Exemptions Emergency activities by governmental entities Agricultural operations Maintenance of existing roads Construction of public roads
9	Permit Fee The proposed permit fee is $100 + $50 for each additional acre, or road mile, disturbed. Fees are for costs of review and a site visit by a District inspector. Permits can be renewed without additional fees each year construction continues.
