COMMENTS OF THE BOARD OF LAKE TOWNSHIP TRUSTEES ON
THE PROPOSED CHANGES TO THE REMEDY AT THE

INDUSTRIAL EXCESS LANDFILL SUPERFUND SITE PAGES 6 - 12

 As Mr. Munro implies in his letter, the USEPA is proposing to address the current conditions, not to implement a permanent remedy as required by CERCLA and the NCP. USEPA is proposing to treat the symptoms without diagnosing the illness. Although the NCP allows the phasing of remedies, phased remedies are not intended to develop a final remedy through trial and error.

CERCLA and the NCP call for permanent remedies based upon good science; however, that is not what is proposed for the instant site. The proposed remedy as an iterative process was presented by Ross del Rosario at the public hearing held by USEPA. He suggested that if the proposed remedy didn't work as anticipated, and a problem was found during an unspecified "monitoring program" or the five year review required for Superfund Sites where waste has been left in place ( 42 USCA 96_, 40 CFR 300.   ), the agency would catch the problem then. This approach does not reduce the volume, toxicity, mobility and bioaccumulation of hazardous substances or maintain protection over time or prevent additional exposures of the offsite population to hazardous substances as contemplated by CERCLA. It merely responds to additional releases of hazardous substances after they may have occurred.

Since about 1994, the PRPs have theorized that all of the offsite contaminants, volatile organic compounds and heavy metals, are being naturally attenuated. Further, they claim that no cap is needed to address the residual waste mass in the landfill itself. Based upon its significant knowledge of Ohio geology and the new information gathered, and its review of the existing record, Bennett and Williams hypothesizes that the contaminants have been flushed from the landfill into the downgradient ponds, streams, wetlands and bogs, which serve as discharge points for groundwater from the landfill.

(See the Bennett & Williams report for detail.) Depending on which theory is correct, the final remedy for the site may differ.

Although the USEPA admits that it does not know what is going on at the landfill, it has proposed to accept the theory of natural attenuation promoted by the PRPs and base the final remedy upon it. The Geraghty and Miller and Sharp and Associate reports that the PRPs submitted to the Agency contain a good discussion of the mechanisms of natural attenuation; however, they do not provide sufficient empirical scientific data to demonstrate that natural attenuation is in fact occurring at the site for both the volatile organic and heavy metal contaminants. If the natural attenuation is the correct scientific explanation for what is occurring at the IEL Site, it can and should be supported by reliable substantive empirical data. To date, it is not.

Internal USEPA memoranda of Linda Kern dated July 1995, Ross Del Rosario dated December 17, 1997 and Mary Randolph, Ph. D. in March of 1998 (which are in the administrative record) discussing natural attenuation at the IEL Site all indicate that insufficient data exist to support the theory that natural attenuation, capable of remedying all of the hazardous substances at the site, is occurring. Mr. Tom Shalala, a certified professional geologist with the firm of Clayton Environmental, experienced in Ohio geology, resides within one quarter mile of the Industrial Excess Superfund Site. He testified at the public hearings held by the USEPA Ombudsman and the USEPA in association with the proposed changes to the remedy that the quantity, quality and nature of the scientific evidence that the USEPA is relying upon to adopt a natural attenuation remedy at IEL falls seriously short of that generally considered sufficient by the USEPA and the professional environmental community (See Ombudsman's transcript and

USEPA transcript attached as Exhibits B and C, respectively and incorporated herein). Bennett and Williams presents a comprehensive review of the natural attenuation issue in their report. They, too, indicate that insufficient hydrogeological, geochemical and microbial evidence exists to support the conclusion that natural attenuation is a proper remedy, even when accompanied by a cap. In addition, the mistakes of fact made during the site characterization alter the assumptions underlying the natural attenuation theory. Bennett and Williams also explain that the protocols for determining the viability and fact of natural attenuation at a site established by the USEPA at its own Kerr Environmental Research Center and suggested in the relevant scientific literature on the issue have not been followed at IEL.

The expert opinions of Dr. Mary Randolph, Linda. Kern Tom Shalala, James Titmas (another local expert who testified during the Ombudsman's Hearing) (See Exhibit A) and Bennett and Williams all agree. Others who offered public testimony during the hearings also agree that the record does not support natural attenuation at the facility. The site-specific conditions are not conducive to natural attenuation and the substantive evidence falls short of demonstrating that the fluctuating contaminant levels are attributable to natural attenuation.

The members of the relevant scientific community who have reviewed the data submitted in support of natural attenuation at the IEL Site have found mistakes of fact, serious substantive flaws in the methodologies used and a serious lack of evidence supporting the theory. The theory has not survived peer review. The PRPs' claim of natural attenuation falls outside the range where experts might reasonably differ. Only the PRPs and their experts believe that natural- attenuation has been shown to be

occurring at the site and that it is sufficient to protect human health and the environment from the organic compounds and heavy metals that have been released from IEL. They stand to save, literally, millions of dollars from the proposed remedy change. To adopt natural attenuation as part of the remedy at the IEL site based upon the information currently in the record will be arbitrary and capricious and contrary to law as no sound science supports the decision and, therefore, no rational connection exists between the site conditions and natural attenuation.
Significant New and Relevant Information.
During their review of this matter, Bennett & Williams and the Board of Lake
Township Trustees identified significant new and relevant information not currently in -the administrative record, which is included in the Bennett and Williams report and the comments of the Board of Lake Township Trustees. When factored into the site characterization, this new information significantly changes the conceptual understanding of the site and requires additional site characterization before a final remedy may be selected and designed. It is of such significance that the USEPA must reconsider its remedy selection in its light. (As the Board's investigation continues, it will update and amend these comments with any new information it finds.)

A.      Irrigation Wells

By way of example, Bennett and Williams found in the public records of the Ohio Department of Natural Resources, information regarding groundwater production rates for the two irrigation wells located on the sod farm adjacent to the landfill. In the remedial investigation and the site characterization, these wells were assumed to be

nonproductive.They are not. This new information significantly alters the hydrogeological picture of IEL.

The 1994 USGS report indicates that groundwater flow from the IEL is radial; however it "quickly" returns to the regional east-west flow. No one has determined how quickly. That same report assumed that the irrigation wells were not in use. The pumping rates of the wells reported to Ohio Department of Natural Resources by the well owner rebuts this assumption. In 1998 alone, the irrigation wells pumped 16.4 millions of gallons of water for irrigation! Any conclusions drawn from this erroneous underlying assumption are likely incorrect. Relying upon this USGS report, the USEPA determined, for instance, that the farms and land to the east and south of the landfill were not affected by the landfill and would not receive an alternate water supply. That determination may or may not be correct. This new information requires the USEPA to reevaluate the groundwater flow patterns at the landfill and reconsider its decision regarding the extent of the alternate water supply.

As discussed in greater detail in the Bennett and Williams report, information regarding the irrigation wells confirms the Science Advisory Board determination: new background wells must be installed and integrated into the groundwater monitoring system for complete understanding of the local groundwater regime.

B.         Residential Development of Property to East and South of Landfill.

The Board of Lake Township Trustees has recently learned that farmland east of IEL, adjacent to the sod farm, has been sold for residential development (See Exhibit D attached and incorporated hereto) The area is not served by city water. The area is not in the No Drill Zone established by the County Health Department for the landfill (see Exhibit E),

because it was previously thought to be upgradient of the landfill. To protect the health of the people who will live in this development and drink the groundwater, the issue of groundwater flow direction to the east and south of the IEL Site must at last be put to rest. The impact of the pumping of the irrigation wells must be determined. If

,

contaminated groundwater is pulled eastward by the irrigation wells, the groundwater may not be used for drinking, irrigation or any other purpose as exposure pathways through various environmental media will be closed. The design of the cap may have to be changed and an alternate water supply installed. See Bennett and Williams report for more detail on this issue.

The health of the residents of the area is at stake. Indeed, the information regarding the massive pumping of groundwater by the sod farm combined with the impending residential development of land east of the landfill triggers § 118 of CERCLA which demands that the USEPA place a high priority on this site. Failure to respond to this new information will be arbitrary and capricious and contrary to law and against the public interest.
C.       
Construction of New Stormwater System.

In addition, the USEPA is hereby advised that the stormwater system along Cleveland Avenue and elsewhere in IEL vicinity is going to be upgraded in the next few years. Any design of the remedy at the site must be coordinated with the county engineer and other agencies involved in this endeavor. Care must be taken that the new stormwater system will not compromise the Industrial Excess Landfill in its current condition or with a cap in place. Conversely, care must be taken to ensure that the installation of the cap will not compromise the stormwater system.
 

Similarly, care must be taken to ensure that construction of either project will not damage or the other. More importantly, the potential exposure of construction workers to hazardous substances such as heavy metals and volatile organic compounds that have left the site and may have entered or accumulated in the existing stormwater system and the adjacent soils must be assessed and a worker health and safety program developed for a stormsewer construction workers.

The additional site assessment work recommended in the Bennett and Williams report must be completed before the storm sewer design is completed and construction is begun to identify what soils may be contaminated. Only in this way can USEPA prevent unnecessary exposures of the workers to hazardous substances, or volatilization of VOCs.

Community Involvement.

The USEPA has not provided the public with a meaningful opportunity to comment on the proposed remedy. First as set forth in Exhibits F and G, and H the agency did not provide adequate time in which to comment. More importantly, the USEPA did not provide sufficient detail on the proposed remedy. As set forth in the Bennett and Williams report, little detail - on the changes to the proposed cap was provided. Similarly, only general statements that a groundwater monitoring program that may include radiochemical parameters will be instituted, were provided. Conceptually the idea is fine, as is motherhood and apple pie. The key to providing an opportunity for meaningful public involvement as required by the NCP, is to provide sufficient details so the public can understand what is really to be done. Without reasonable detail on a proposed remedy, the comment period is meaningless. Public involvement is a cornerstone of the NCP and CERCLA. Failure to comply with the communit
