Control all Site ~lated discharges to Conoy Creek and the tributaries so that PASWQS are· satisfied*.

Coritrol all Site related discharges to Conoy Creek and the tributaries to prevent future impacts to sediments related to the Site contaminants of concern.

·Prevent to the extent technically practicable, lnfihration and the resulting lea::hate generation In the southern portion of the landfill (which Is potential source for the Identified groundwater impacts and an area with doWnward hydraulc grSclients).

Continue to collect and treat landfill gas.

Comment No. 1;

§3.3 (page 6) ·.

SCA asserts that a fenceline around the Landfill prevents exposure· to contaminated . waste, sons, and sediments. Additional measures designed to prevent exposure from

ingestion and dermal contact (such as capping, etc.) must be included in ihe Feasibility. Study since the fenceline does not satisfy the long-term protectiveness provisions and · other requirements of CERCLA and the NCP. · ·

Response to Comment No.1;

Cappin~ alternatives· are included ·in the Feasibility Study ~S) report. · ·

Comment No. 2; ·

§5.2 (page 14) .

SCA must in~lude air monitoring in the general response acti9ns for landfill gas and alr/d~ controL

Response to Comme~t No. 2;

On-going landfill gas monitoring is an ·integral part of each retained alternative. Air monitoring .~d dust control will be impl~mented during CO:f'struction.

Comment No. 3:

· §5.2.1 (page 15)

SCA must explain· the .~ature of. ·the proposed "upgrades." to· the existing . gas management system and must specify the conceptual d~sign of such "upgrades".

Response to Comment No, 3;

· SCA has submitted a request for a determination of need for an all permit to PADER. . Based upon PADER's determination, SCA will either continue its current operation of the · existing flare or will. upgrade· the open flare to an enclosed flare sy~tem. 1be possible upgrade is discussed in the FS report.

EPA will not select a pro~able ()r potential r~mediaJ action until the RI and .FS .reports have been· fully reviewed and evaluated. The Agency does not endorse SCA's opinions on the "po~ential remedial action" that are depiCted in Figures 5, 6, and 7 •.

Furth~r explanation must be provid~d 'on why subsurface drains wo:Wd not be effective, · Particularly for leachate. · · ·

Response to Comment No. i2:

SCNGolder conSider that the existing toe.drain is effective for the northern e~tremlty of the Landfill. However, installation or extension of the subsurlace drains back through the center and to the southern portion of the. Landfill would no~ be expected to be as effective as downward vertical gradients provide a driVing force for leachate. migration . directly to the bedrock beneath the fill rather than laterally to subsurface··drains. In addition; Construction of su~ drains may prove difficult if unweathered bedrock is · e~countered above the desfred grade of .any proposed drains.· Given. the expected . effective~ess of cover alternatives retained for detailed analysis, significant generation of additional leachate is not :expected. · ·

There Is no apparent reason for separating the chemical oxidation technologies. The· FS must include chemical oxidation alternatives that use combinations of oxidants and the: eval~ation of this technology should be_ appro.ached as broadly as possible.

The TSER a~d Appendix E broadly diSc:uss. cheinlcal. oXidation technologies as . technologies which include UV radiation with either hydrogen peroxide and/or ozone. Just as there are several manufacturers of air stripping technology processes, there are ~several types of chemical oxidation technologies that include _UV-peroxidation, UV-ozonation, and UV-peroXidation and ozonation. The final choke of the precise treatment

. process will be made during Remedial Design, if needed, should chemical, oxidation be selected-as the prlm~ry· treatment' process. . · · · . · · .

Some leachate exists in a fairly thln·saturated thickness in the soillweathered bedrock at · shallow depth ben~ath the landfill. ·.-However, a considerable portion of leachate · conStituents migrate downward to the shallow water table and then continue to move

do\vnward and downgradient within the groimdwater under the influence of vertical and lateral hydraulic gradients. The source control extraction ~ells proposed as part of the retained alternatives h~ve been conceptually designed to intercept this impacted groundwater (see Appendix 'D). · ·

Bedrock conditions that preclude application of vertical barriers must be better · explained. ·

Res.ponse to Comment No. 17: · I .

Vertical barriers can be broadly described _as vertical structures of clay, steel or concrete which restrict the lateral movement of impacted groundwater. Besides the inherent , diffiClllty of trying to advance· and install these structures in dipping bedrock (of varying. strengths of strata), these structUres would not be expected to be very effective for vertical · groundwater flow under the influence of downward vertical gradients existing beneath. · a major part of the Site.

The ~ue of carbon adsorption of vinyl chloride has ~en considered in. the FS Report_ an~ as dl~sed below. It should be noted that vinyl chloride Will adserb onto carbon, but as with some other compounds such as acetone~ the carbon usage rates will be higher than considered "normal". :The requirement to address· higher usage rates for the less

Appendix E of the FS Report discusses metals an~ vinyl chloride removal with respect tO site-specific influent.

Potential fouling of any GAC unit selected will be given due consideration during Remedial Design. ·

Vinyl chlorlde Will adsorb onto carbon. However, to meet the very low discharge criteria mentioned in the above co~ent, excessive carbOn may be used in the process to obtain these·effllJent limits.

It Js acbtowledged that it i~ mo~e difficult ·for. th~ chemi~aloxidation pr~cess to destroy saturated orgarucs (e.g., trichloroethane) than unsatUrated organics· (e.g. trichloroethylene). Specifically, higher energy inputs, higher chemical doses and longer retention times are generally required· to effectively treat saturated compounds. However, there are othet treatment technologies which should more efficiently treat these compounds .and ~ese technologies (e.g. air stripping and GAC) are lnc:luded in the treatment processes discuss~d in Appendix E of the FS _ Report. . · · · ·

Leachate flow from the toe-dram collection system eXisting at the site is .known to. vary considerably from high flows in early spring, to. very .low flows in late sumnter/fall when the grouriclwater table likely drops below ~e level of the collector drains. ·Thus, for the latter condition the only leachate collected via the system is that resulting from "trickle" flow through the waste itself.
