Supplemental proposed rule; extension of comment period.


The Environmental Protection Agency (EPA) is announcing that the comment period to the supplemental proposed rule entitled Revisions to the Definition of Solid Waste published on March 26, 2007 (72 FR 14172) is being extended until June 25, 2007. In the supplemental proposal, EPA is requesting comment on revisions to the definition of solid waste which would exclude certain hazardous secondary materials from regulation under Subtitle C of the Resource Conservation and Recovery Act (RCRA). We are also soliciting comment on regulatory factors to be used to determine whether recycling of hazardous secondary materials is legitimate.


The comment period for this supplemental proposed rule is extended from the original closing date of May 25, 2007, to June 25, 2007.

A. Comment Period. We are extending the comment period by 30 days in response to requests from several stakeholders.

B. Regulated Entities. Entities potentially affected by this action include about 4,600 facilities in 530 industries in 17 economic sectors that generate or recycle hazardous secondary materials which are currently regulated as RCRA Subtitle C hazardous wastes (e.g., industrial co-products, by-products, residues, unreacted feedstocks). About 80 percent of these affected facilities are classified in NAICS code economic sectors 31, 32, and 33 (manufacturing), and the remainder are in NAICS code economic sectors 21 (mining), 22 (utilities), 23 (construction), 42 (wholesale trade), 44 and 45 (retail trade), 48 and 49 (transportation), 51 (information), 54 (professional, scientific and technical services), 56 (administrative support, waste management and remediation), 61 (educational services), 62 (health care and social assistance, and 81 (other services). About 0.65 million tons per year of recyclable industrial materials handled by these entities may be affected, of which the most common types are metal-bearing hazardous secondary materials (e.g., sludges and spent catalysts), and organic chemical liquids. This proposed rule, if promulgated, is expected to result in regulatory and materials recovery cost savings to these industries of approximately $107 million per year. Taking into account impact estimation uncertainty factors, this rule, if promulgated, could affect between 0.3 to 1.7 million tons per year of industrial hazardous secondary materials handled by 3,600 to 5,400 entities in 460 to 570 industries, resulting in $93 million to $205 million per year of net cost savings. More detailed information on the potentially affected entities, industries, and industrial materials, as well as the economic impacts of this rule (with impact uncertainty factors), is presented in the “Economics Background Document” available in the docket for this rulemaking.

C. Submitting CBI. Do not submit this information to EPA through or e-mail. Clearly mark all information that you claim to be CBI. For CBI information in a disk or CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as CBI and then identify electronically within the disk or CD-ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed, except in accordance with procedures set forth in 40 CFR part 2.
