This issue also presents highlights from the FY1989 ROD Analysis and FY1989 ROD Annual Report. FY 1989 ROD Analysis In January 1990, the annual ROD Analysis was conducted by the Office of Emergency and Remedial Re- sponse (OERR) and the Office of Waste Programs Enforcement (OWPE). One hundred and thirty-nine RODs (all but 4 FY 1989 RODs) were ana- lyzed. The results of the analysis are presented in OSWER Directive 9355.3-09, issued March 30, 1990., Copies have been distributed to Re- gional Division Directors. The analy- sis focused on the consistency of remedies with program expectations regarding the appropriate use of treat- ment technologies, containment, and institutional controls, and the quality of ROD documentation. The analysis found that remedies generally are consistent with the expectation to treat materials comprising the principal threats posed by the site- liquids, highly toxic or highly mobile waste (e.g. waste posing threats several orders of magnitude above health- based levels). Materials presenting low-level threats are generally being contained, although such materials were being treated in some cases (which may have been the most cost- effective approach, given economies of scale) and were not always clearly delineated. The FY 1989 ROD Analy- sis noted improvements in the quality of the ROD documentation, particu- larly those areas targeted for improve- ment as a result of last year's ROD Analysis. The analysis identified five additional areas which should be emphasized in developing high quality RODs in FY 1990. 1. Documenting Site Risks This area is the most important as- pect of the ROD slated for improve- ment for FY 1990. Final Action RODs should summarize the results of the baseline risk assessment conducted for the site. RODs should also clearly identify both the total carcinogenic and noncarcinogenic risks for the populations at risk at the site via each exposure pathway. Exposure as- sumptions should be clearly identi- fied, including current and future ex- pected land use. RODs should also include a summary of the environ- mental risks. 2. Describing principal and low level threats Generally, FY 1989 RODs included relatively clear descriptions of the material comprising principal threats posed on a site. However, the analy- sis showed that low-level th reats cou Id be defined more clearly in many cases. A clear definition of principal versus low-level threats is necessary for measuring the consistency of reme- dies with the program expectations. In order to differentiate these threats, the "Summary of Site Characteris- tics" section of the ROD should link contaminant concentrations and vol- umes to specific areas of the site. 3. Documenting ARARs, particu- larly the Land Disposal Restric- tions (LDR) Sections of the ROD documenting ARARs are: Description of Alterna- tives, Comparative Analysis, and Statutory Determinations. The De- scription of Alternatives section sum- marizes how the components of each alternative will comply with the major ARARs and describes why the re- quirement is ARAR. The Compara- tive Analysis summarizes which of the alternatives are fully ARAR com- pliant or require any waivers. Finally, under the Compliance with ARARs finding in the Statutory Determina- tions section, each ARAR the se- lected remedy will attain should be listed and proper citation provided. This year's analysis showed that im- provement is needed in documenting a determination of whether wastes at the site are RCRA wastes, whether LDR is an ARAR (which should ap- pear in all RODs), and whether RCRA closure requirements are ARARs. Continued on page 2 ------- 4. Increasing the use of treatablllty studies conducted during the re- medial Investigation to support the selection of Innovative technolo- gies This year's analysisfound that treata- bility studies are often not conducted during the Remedial Investigation, but rather planned for remedial design. Innovativetreatment technologies are sometimes eliminated from consid- eration when treatabilrty studies have not been conducted priortotheROD. Specifically, treatability studies were completed prior to ROD signature for approximately 17% of source control RODs or remedies and six percent of final ground water treatment remedies. Thirty-six (36) additional treatability studies are planned to be conducted during the remedial design phase for final source control actions. The FY 1989 ROD Analysis found that the use of treatment, including innovative treatment technologies, is increasing annually. The FY 1989 ROD Annual Report (see article on p. 3) states that 26% of FY 1987 source control RODs used innovative treatment technolo- gies, whereas 51 % of FY 1989 source control RODs made use of innovative treatment technologies. 5. Documenting points of compli- ance and remediation goals The description of the selected rem- edy should provide the remediation goals and the points of compliance for each medium or area at the site that is being addressed. The analysis found that 62% of the final source control RODs provided remediation goals and 33% specified the points of compliance for each medium. Eighty-seven percent of fi- nal ground-water RODs provided remediation goals.

Q: What triggers the RCRA Mint- mum Technology Requirements (MTR)? A: The MTRs under RCRA require that a unit be double lined and have a leachate collection system. (Note that if a unit is required to meet MTRs it must also be in compliance with other RCRA design standards.) MTRs are required for new units, re- placement units, and lateral expan- sions of existing landfills 140 CFR 264.301 (c)] and surface impound- ments [40 CFR 264,321 (c)J. A lateral expansion Is defined to be an expansion of the boundaries of an existing unit, Replacement occurs rf a unit is emptied and reused. Reuse occurs if original waste is removed from a unit and different waste (either ROD Q & A treated or untreated from other units) is put into the unit. If waste is re- moved from a unit or area of contam i- nation, treated, and put back into the same unit, replacement does not oc- cur.

Q: Can waste that has been removed from an area of contamination (AOC) and treated in compliance with the re- quirements under the land Disposal Restrictions (LDR) be redeposited in the same AOC from which if was re- moved without triggering MTRs? A: Yes. The NCR states. "EPA gen- erally equates the area of contamina- tion with a single RCRA tandbased unit, usually a landfill (54 FR 41444). In most cases, these AOCs are not subject to the design and operating requirements for Subtitle C landfills (40 CFR 301) because they are viewed as portions of a landfill. MTRs would not apply in this case, for two reasons: 1.) The redeposi- tion of the treated waste info the AOC would not cause the AOC to be considered a replacement unit; 2<) MTRs would not apply because the AOC is not receiving "new" waste, and thus, is not being reused, Q: Are there circumstances under which MTRs should be used, but are not ARAR? A: Yes, High concentrations of waste posing a significant threat to groundwater Sf nottreated generally should be managed in units meet* ing MTRs. Liners and leachate col- lection systems will often be appro- priate to assure long-term protec- tive containment systems.

The data in the report are based on 143 RODs (139 RODs and 4 ROD Amendments), including Fund-lead, Enforcement-lead, and Federal Fa- cility RODs that were signed during FY 1989. Ninety-five (95) of the FY 1989 RODs addressed final source control. The remaining 48 RODs selected interim source control ac- tions (10), ground water remedies only (26), or no action/no further action (12). Forty-eight (48) RODs selected both source control and ground water remediation compo- nents. In keeping with CERCLA Section 121 and the NCR's program expectations, source treatment was selected in almost 73% (69 of 75) final source control RODs. (See Exhibit 1 below forthe numberof final and interim source control remedies employed in each treatment category.) The report is a reference document and is divided into the following five sections: Introduction - highlights specific ac- complishments in the ROD process and gives an historical overview. FY 1989 ROD Abstracts - describes site conditions, key contaminants, selected remedial actions, perform- ance standards, institutional controls, costs, and site-specific keywords for each FY 1989 ROD. FY 1989 ROD Summary Table - pro- vides the remedial action site name and date of ROD signature, and sum- marizes the threat or problem, the contaminants by media, waste vol- ume, components of the selected remedy, cleanup goals and costs for each FY 1989 ROD. FY 1982-1988 ROD Summary Table - provides the remedial action site name and ROD signature date, and summarizes the threat or prob- lem, waste volume, major compo- nents of the selected remedy, and costs for each FY 1982-1988 ROD. ROD Keyword List - provides a sum- mary listing under each keyword of all RODs that have an association with the keyword based on the selected remedial action The FY 1989 ROD Annual Report will be printed and mailed to the Regions in June 1990. Copies will also be made available to the public.

Out of the total of 581 RODs. 37 ARAR waivers were invoked in 31 RODs (5 percent). The following RODs: Diamond Alkali, NJ; Ambler Asbes- tos, PA (both 1988 and 1989 RODs), and Libby Ground Water, MT invoked two or more waivers, while one ROD (Operating Industries #3, CA) invoked one waiver while at the same time possibly invoking another waiver. Seymour Recycling, IN and Broder- ick Wood Product, CO both stated the possibility of invoking the Techni- cal Impracticability Waiver. Two RODs did not specify which type of waiver was invoked.
