LDR Rules and Regulations 1998

Date: Sept. 24, 1998
Citation: 63 FR 51254
Subject: LDR, Treatment Standards for Spent Aluminum Potliners (K088)(PDF) (14 pp, 131K, About PDF), Final Rule
Abstract: This rule promulgates revised treatment standards for spent aluminum potliners (K088). This action is being taken in response to a Court decision on April 3, 1998, on the Phase III K088 treatment standards. The Court vacated all the Phase III K088 treatment standards. This rule promulgates interim replacement standards.

Date: Sept. 4, 1998
Citation: 63 FR 47410
Subject: LDR, Phase III--Emergency Revision of Treatment Standards for Listed Hazardous Wastes from Carbamate Production (PDF) (9 pp, 71 K), Final Rule
Abstract: This rule revises sets final alternative carbamate treatment standards for seven hazardous specific carbamate wastes for which there are no analytical standards. These carbamate wastes may be treated to meet the concentration limits set as the treatment standards or may be treated by the technology used as the basis for the concentration limits. The rule also deletes the treatment standard for one additional constituent for which available analytical methods have not been shown to achieve reliable measurements. These eight constituents are being removed from the Universal Treatment Standard list. The rule clarifies that the numerical treatment limits apply to the remaining 32 carbamate wastes.

Date: Aug. 31, 1998
Citation: 63 FR 46332
Subject: LDR, Hazardous Waste Recycling, Zinc Micronutrient Fertilizer (PDF) (14 pp, 371K, About PDF), Final Rule
Abstract: This rule amends the Phase IV rule (63 FR 28556) for zinc micronutrient fertilizers produced from toxicity characteristic wastes. Rather than being subject to the treatment standards promulgated in the Phase IV rule, the fertilizers affected by this amendment remain subject to the treatment standards for toxic metals in place prior to Phase IV.

Date: Aug. 6, 1998
Citation: 63 FR 42110
Subject: Identification and Listing of New Petroleum Refining Wastes, Final Rule - Part One (PDF) (8 pp, 147K, About PDF); Part Two (PDF) (14 pp, 371K, About PDF)
Abstract: This final rule adds four wastes generated from petroleum refining to the list of hazardous wastes. The rule also deems 10 other petroleum refining wastes non-hazardous. LDR treatment standards apply to the four newly listed wastes.

Date: Aug. 4, 1998
Citation: 63 FR 41536
Subject: LDR Phase III--Spent Potliners from Primary Aluminum Reduction (K088)(PDF) (3 pp, 153K, About PDF), Notice Of Data Availability
Abstract: This notice presents data on the treatment of arsenic in K088.

Citation: 63 FR 31463
Subject: Hazardous Waste Land Disposal Restrictions: Notice of Public Meeting
Abstract: The Environmental Protection Agency's (EPA's) Office of Solid Waste, OSW (renamed Office of Resource Conservation and Recovery, ORCR, on January 18, 2009) will hold a public roundtable discussion on the Agency's efforts to evaluate important aspects of and potentially improve the Resource Conservation and Recovery Act (RCRA) Land Disposal Restrictions (LDR) Program. The purpose of the roundtable is to enable individuals who have substantial experience in implementing the LDR Program to offer their own evaluations and suggestions on possible improvements to the program. EPA's overall goal in the LDR reinvention project is to examine the best way to ensure the program is environmentally protective, less expensive, more efficient and flexible, clearer to the public, and more enforceable. The public is welcome to observe the discussions among participants and will be afforded some opportunities to express their views. However, this meeting is not intended to be a full public hearing.

Date: June 8, 1998
Citation: 63 FR 31266
Subject: Phase IV (PDF) (3 pp, 154K, About PDF), Correction
Abstract: This technical correction amends wording in the appendix of the final rule of Phase IV, released on May 26, 1998.

Date: May 26, 1998
Citation: 63 FR 28556
Subject: LDR, Phase IV–Treatment Standards for Metal Wastes and Mineral Processing Wastes; Mineral Processing Secondary Materials and Bevill Exclusion Issues; Treatment Standards for Hazardous Soils, and Exclusion of Recycled Wood Preserving Wastewaters; Final Rule
(See also Soil Treatment Standards)
Abstract: This final rule promulgates LDR treatment standards and effective dates for metal bearing-wastes, including those generated by mineral processing operations. The rule revises 12 metal Universal Treatment Standard constituents. The rule also defines which secondary materials from mineral processing are considered to be wastes and potentially subject to the LDRs. In addition, the rule sets alternative standards for contaminated soil. The rule also excludes shredded circuit boards used in recycling operations as well as specific wood preserving wastewaters from the definition of solid wastes.

Subject: Information Collection Request for the Land Disposal Restrictions Surface Impoundment Study (See also ICR Background Information)
Abstract: The U.S. Environmental Protection Agency (EPA) is conducting a study of facilities which manage industrial waste in surface impoundments. Part of the study is mandated by Congress under the 1996 Land Disposal Program Flexibility Act. Congress asked EPA to characterize risks posed by managing wastewaters in surface impoundments that are regulated under the Clean Water Act, and to determine whether existing regulations adequately address risks that may be present. The scope of the study covers industrial wastewaters. The study does not, however, cover wastewaters that are classified as hazardous wastes under the federal Resource Conservation and Recovery Act (RCRA). EPA will characterize the population of nonhazardous waste surface impoundments in the United States and estimate the potential human health and ecological risks from chemical releases from nonhazardous surface impoundments. EPA will use mathematical models to represent the transport of chemicals from entry into surface impoundments to their uptake by a human or ecological receptor. While the models are simplified representations of the complex biological, chemical and physical processes occurring in the impoundments and the environment, the models require considerable data.
