Document Type
NOE - Notice of Exemption
Present Land Use
Document Description
South Coast AQMD staff is proposing to amend Rule 1117 to: 1) establish emission standards for oxides of nitrogen (NOx) and oxides of sulfur (SOx) from facilities that produce container glass and sodium silicate and are transitioning from Regulation XX – Regional Clean Air Incentives Market (RECLAIM) to a command-and-control regulatory structure; 2) update monitoring, reporting, and recordkeeping requirements; 3) establish provisions for the idling, startup, and shutdown of container glass melting and sodium silicate furnaces; and 4) include NOx emission limits for auxiliary combustion equipment associated with container glass melting operations. Other minor proposed amendments include adding new and modifying definitions of terms and removing obsolete requirements for clarity and consistency throughout the rule.

Notice of Exemption

Exempt Status
Type, Section or Code
Section 15061(b)(3)
Reasons for Exemption
Pursuant to the California Environmental Quality Act (CEQA), South Coast AQMD, as Lead Agency, has reviewed Proposed Amended Rule 1117 pursuant to: 1) CEQA Guidelines Section 15002(k) – General Concepts, the three-step process for deciding which document to prepare for a project subject to CEQA; and 2) CEQA Guidelines Section 15061 – Review for Exemption, procedures for determining if a project is exempt from CEQA. Since air pollution control equipment was previously installed for the furnaces at the affected facilities prior to the development of Proposed Amended Rule 1117, and the actual emissions have been demonstrated to be less than proposed emission standards, no physical changes that would adversely affect any environmental topic area would be expected to occur as a result of project implementation. For these reasons, it can be seen with certainty that there is no possibility that the proposed project may have a significant adverse effect on the environment. Therefore, the project is exempt from CEQA pursuant to CEQA Guidelines Section 15061(b)(3) – Common Sense Exemption.
