RULE ANALYSIS

Purpose of the rule or reason for the change:

The proposed changes incorporate corresponding revisions made by EPA in a final rule published in the Federal Register on 11/28/2016 (81 FR 85732) under the title of Hazardous Waste Generator Improvements Rule (HWGIR). As an authorized state for the hazardous waste program, the proposed changes are made in order to maintain regulatory equivalency with the federal hazardous waste regulations. Similar changes are proposed in other rules under Title R315 in order to incorporate all of the corresponding revisions promulgated under the final HWGIR by EPA on 11/28/2016.

Summary of the rule or change:

On 04/13/2017, the Waste Management and Radiation Control Board authorized the proposed changes to be published for public review and comment. Proposed changes to Section R315-301-2 reflect those corresponding revisions made by the final HWGIR to 40 CFR 258, as promulgated on 11/28/2016 (81 FR 85732). While many of the changes are required to retain primacy of the hazardous waste program, others provide added clarification or correct textual errors. Specifically, incorporating into Section R315-301-2 and into the other companion rules of Title R315, the revisions promulgated by EPA make significant improvements to the hazardous waste generation requirements by: 1) reorganizing and consolidating the generator requirements for added convenience and clarity, 2) providing added flexibility for generators to manage their hazardous waste in a more cost-effective and equally protective manner, and 3) revising the title of the lowest category of hazardous waste generation from "conditionally exempt small quantity generator" to "very small quantity generator". The change in the title of the lowest category of hazardous waste generation will result in less confusion on the part of hazardous waste generators regarding the essential requirements for managing hazardous waste produced in very small quantities. Changing the title of this generation category to "very small quantity generator" makes clear that limited rules apply to the generation and management of hazardous waste in very small quantities rather than potentially mislead by using the phrase "conditionally exempt", which may imply that no requirements or rules apply.

Statutory or constitutional authorization for this rule:

• Section 19-6-105
• Section 19-6-108
• 40 CFR 258
• Section 19-6-106
• Section 19-6-109

Anticipated cost or savings to:

the state budget:

Based on EPA's regulatory impact assessment (September 2016) for the HWGIR, state agencies that generate hazardous waste may realize an undetermined portion of the aggregate annual net cost savings of $3,600 to $13,100 for all Utah hazardous waste generators.

local governments:

Based on EPA's regulatory impact assessment (September 2016) for the HWGIR, local governments that generate hazardous waste may realize an undetermined portion of the aggregate annual net cost savings of $3,600 to $13,100 for all Utah hazardous waste generators.

small businesses:

Based on EPA's regulatory impact assessment (September 2016) for the HWGIR, small businesses that generate hazardous waste may realize an undetermined portion of the aggregate annual net cost savings of $3,600 to $13,100 for all Utah hazardous waste generators.

persons other than small businesses, businesses, or local governmental entities:

Based on EPA's regulatory impact assessment (September 2016) for the HWGIR, other persons that generate hazardous waste may realize an undetermined portion of the aggregate annual net cost savings of $3,600 to $13,100 for all Utah hazardous waste generators.

Compliance costs for affected persons:

In the regulatory impact assessment issued by EPA (September 2016, EPA-HQ-RCRA-2012-0121-0313, regulations.gov) for the final HWGIR, EPA estimated that by applying the rule changes, all hazardous waste generators can potentially realize a national aggregate net compliance cost savings from $722,000 to $2,630,000, annually. The total number of Utah hazardous waste generators is about 0.5% of the national total. Therefore, given the national total, the annual net cost savings to all Utah hazardous waste generators may range from $3,600 to $13,100.

Comments by the department head on the fiscal impact the rule may have on businesses:

In the regulatory impact assessment issued by EPA (September 2016, EPA-HQ-RCRA-2012-0121-0313, regulations.gov) for the final HWGIR, EPA estimated that by applying the rule changes, all hazardous waste generators can potentially realize a national aggregate net compliance cost savings from $722,000 to $2,630,000, annually. The total number of Utah hazardous waste generators is about 0.5% of the national total. Therefore, given the national total, the annual net cost savings to all Utah hazardous waste generators may range from $3,600 to $13,100.

Wetlands generally include swamps, marshes, bogs, and similar areas.
