Stakeholder Final, Historical Records Review Ravenna Army Ammunition Plant, Ohio EXECUTIVE SUMMARY Under contract with the United States Army Corps of Engineers (USACE), Omaha District; engineering- environmental Management, Inc. (e2M) has prepared the following Historical Records Review (HRR) Report for the other than operational ranges and sites with known or suspected unexploded ordnance (UXO), discarded military munitions (DMM), or munitions constituents (MC) at Ravenna Army Ammunition Plant (RVAAP), located in Portage and Trumbull Counties, Ohio. These Munitions Response Sites (MRSs) at RVAAP are being evaluated under the United States (US) Army Military Munitions Response Program (MMRP). The intent of the HRR is to perform a limited-scope records search to document historical and other known information on the MRSs identified at RVAAP to supplement the United States (US) Army inventory of closed, transferring and transferred (CTT) military ranges and defense sites with UXO, DMM or MC; and to support the Technical Project Planning (TPP) process designed to facilitate decisions on those areas where more information is needed to determine the next step(s) in the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) process. Primary sources of information researched as part of the data collection effort for the HRR included an installation site visit; a review of existing historical documents, maps/drawings, photographs, and investigative reports comprising the Administrative Record (AR); interviews with installation personnel; and reviews of the US Army CTT Range/Site Inventory, Archive Search Report (ASR), and supporting documentation. After reviewing the information collected during the HRR, the following conclusions have been made for the MRSs at RVAAP: • Nineteen MMRP-eligible sites were identified during the US Army CTT Range/Site Inventory. • Since the completion of that phase, Winklepeck Burning Grounds (WPG) (RVAAP-005-R-01)1 has been addressed under Base Realignment and Closure (BRAC) and Installation Restoration Program (IRP) funding. Chemical contamination at the MRS was addressed under the IRP, whereas BRAC funding was used to address explosive safety. Further, the MRS is no longer eligible for the MMRP since the parcel is being developed as an operational range (Mark 19 Range) by the Ohio Army National Guard (OHARNG). Therefore, this MRS has been removed from the MMRP. 1 Army Environmental Database-Restoration (AEDB-R) Number January 2007 (revised) i USACE Omaha\MMRP\Ravenna AAP\HRR Final\Ravenna Final HRR 011907 Stakeholder Final, Historical Records Review Ravenna Army Ammunition Plant, Ohio • The remaining eighteen MRSs qualify due to the demolition and/or disposal activities that were conducted which resulted in the potential presence of munitions and explosives of concern (MEC) and/or MC, and where releases occurred prior to September 2002. Furthermore, based on additional information collected during the HRR, the original site descriptions, acreage, and/or boundaries for six of the MRSs were modified. These modifications are summarized below: • Ramsdell Quarry Landfill (RVAAP-001-R-01), realignment of the MRS boundary and increase in acreage from 3.79 acres to approximately 13.43 acres; • Demolition Area #2 (RVAAP-004-R-01), realignment of the MRS boundary and increase in acreage from 14.91 acres to approximately 32.95 acres; • Load Line #1 (RVAAP-008-R-01), realignment of the MRS boundary and decrease in acreage from 163.62 acres to approximately 4.63 acres; • Load Line #12 (RVAAP-012-R-01), realignment of the MRS boundary and decrease in acreage from 77.58 acres to approximately 1.0 acre; • Landfill North of Winklepeck (RVAAP-019-R-01), realignment of MRS boundary and increase in acreage from 7.55 acres to approximately 14.05 acres; and • Firestone Test Facility (RVAAP-033-R-01), realignment of the MRS boundary and increase in acreage from 0.25 acres to approximately 0.91 acres. Ramsdell Quarry Landfill (RVAAP-001-R-01) Based on information provided by the Installation, the MRS boundary identified during the US Army CTT Range/Site Inventory may not capture the full extent of MEC, which may extend further to the north and south of the current MRS location. This was supported by information presented in the IRP reports which revealed the landfill is not situated in the bottom of the quarry where open burning/open detonation (OB/OD) operations took place, but rather along the southern and western rim of the excavation, which correlates to the location of the current MRS boundary. Based on this, it is understood the current MRS boundary does not completely encompass the OB/OD area formerly used to thermally treat explosives waste and munitions, thus the MRS boundary must be expanded. Further, under the MMRP any MEC that may be present in a capped and closed landfill is not eligible since this is considered a “Response Complete”. Therefore, the MRS boundary has been expanded to the north to include the entire quarry area and to the south to include an area outside the quarry that was identified by the Installation as potentially containing MEC. In addition, the former landfill area has been removed from further consideration as part of the MRS. January 2007 (revised) ii USACE Omaha\MMRP\Ravenna AAP\HRR Final\Ravenna Final HRR 011907 Stakeholder Final, Historical Records Review Ravenna Army Ammunition Plant, Ohio Demolition Area #2 (RVAAP-004-R-01) The 2003 US Army CTT Range/Site Inventory reported that Demolition Area #2 encompassed approximately 14.91 acres, which included a 2.5 acre interim Resource Conservation and Recovery Act (RCRA) unit that was permitted to demilitarize munitions. During the HRR research it was determined that the locations of two known munitions burial sites (i.e., Burial Sites 1 and 2) and a dump area known as the Sand Creek Disposal Area (also referred to as Rocket Ridge) had not been mapped as part of the MRS during the inventory. These areas, and the areas located between them, were found to be MMRP- eligible and have now been included as part of the Demolition Area #2 MRS. Two areas located within the MRS footprint were determined to be non-MMRP eligible. The 2.5 acre interim RCRA unit and a majority of the area that was previously used as a 40millimeter (mm) prototype test range that overlies the interim RCRA unit have been removed from consideration as part of the MRS (RVAAP-6.A.4). Only the small portion of the old prototype test range that extends to the north and outside of the interim RCRA unit is MMRP-eligible and will be included as part of the MRS. The interim RCRA unit will be closed in accordance with all applicable state and Federal regulations and requirements at the end of the IRP investigation. Based on the realignment and addition of new areas, the MRS footprint has been increased to approximately 32.95 acres. Additional information was provided by the Installation that indicated that there is a bomb disposal area located near the northwestern portion of the MRS. While this could not be corroborated by additional documentation, the area will be recommended for further investigation during the site Inspection (SI) process. Load Line #1 (RVAAP-008-R-01) Based on the findings of IRP investigations conducted at the former load line and input from Installation personnel, the only MEC (i.e., residual propellant pellets) present at the MRS is located beside Buildings CB-13, CB-13B, and CB-14, as well as in the area of the former popping furnace. Therefore, the MRS boundary was reduced to those immediate areas surrounding the buildings (i.e., CB-13, CB-13B, and CB-14) and the popping furnace. Load Line #12 (RVAAP-012-R-01) Several IRP investigations have been conducted at the former load line with only one reported finding of potential MEC (i.e., 90mm projectiles). Furthermore, all buildings that were located at the MRS were decommissioned and have been removed, along with any potential MEC. Input from Installation personnel indicated the only suspect area at the MRS is associated with the area immediately surrounding the location where the 90mm projectiles were discovered. Based on the January 2007 (revised) iii USACE Omaha\MMRP\Ravenna AAP\HRR Final\Ravenna Final HRR 011907 Stakeholder Final, Historical Records Review Ravenna Army Ammunition Plant, Ohio comprehensiveness of IRP investigations conducted to date at the load line, and input from Installation personnel, it is reasonable to reduce the size of the boundary to the area immediately surrounding the location where the 90mm projectiles were found. Landfill North of Winklepeck (RVAAP-019-R-01) Installation personnel have reported that potential MEC (booster cups and other nondescript items) is present on the slope leading down to the small stream, outside of the current MRS boundary. To capture this potential MEC, the MRS boundary has been adjusted to cover the area between the landfill and the small stream as identified by Installation personnel.
