1. Site

a. Name: Operation and Maintenance of Sand Creek Barrier System, Rocket Ridge Area of Open Demolition Area #2 (ODA2), Ravenna Army Ammunition Plant (RVAAP), Ravenna, Ohio. Under U.S. Army Corps of Engineers (USACE) Omaha District, see Figure 1.

b. State: Ohio

c. This O&M work is being performed under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), as amended by the Superfund Amendments and Reauthorization Act of 1986 (SARA), and is part of a Time Critical Response Action (TCRA). If subsequent response actions are determined to be necessary, an ESS will be prepared and submitted for review and approval as necessary to support that response.

2. Anticipated Dates

a. Start: May 31, 2008

b. Complete: July 31, 2009

3. Purpose

a. To prevent the downstream movement of munitions and explosives of Concern (MEC) and Munitions Debris (MD) within Sand Creek.

b. Inspection and removal of Munitions and Explosives of Concern (MEC) and Munitions Debris (MD) accumulated on the screens.

c. MEC Storage at Earth Covered Magazine number 1501 located at ODA2, Disposal of MEC by blow in place (BIP), or at the ODA2 demolition site.

4. Site Background and Current Conditions

a. Rocket Ridge is a steep embankment approximately 500 feet long and 25 feet high located adjacent to Sand Creek within ODA2, approximately 2,700 feet upstream of the George Road Bridge.

b. ODA2 was used for munitions demilitarization, including detonation of large caliber munitions and off-specification bulk explosives that could not be deactivated or demilitarized by any other means. The Rocket Ridge slope was used for the disposal of demilitarized munitions, although not all munitions appear to have been completely demilitarized.

c. Munitions were transported from the demolition site to Rocket Ridge and dumped at the top of the slope. Sand Creek flows in an eastward direction along the northern boundary of the Rocket Ridge Area of ODA2, at the toe of the slope. Due to the steep slope of the disposal



Ravenna, Ohio


area and the stream bank erosion resulting from high water events, some of the munitions materials have reached Sand Creek.

d. On 18 June 2007, a rifle grenade containing white phosphorus exploded on the slope of Rocket Ridge. A survey conducted on 5-6 November 2007 upstream of the George Road Bridge identified a piece of munitions debris approximately 1,200 feet downstream of Rocket Ridge. Thirteen additional magnetometer anomalies from buried sources were found in the stream between the piece of munitions debris and the location of the barrier system. The sources of these subsurface anomalies have not been investigated.

e. In order to prevent the downstream movement of MEC within Sand Creek, the Army constructed a barrier system. The barrier system will be installed across Sand Creek approximately 2,700 feet downstream of Rocket Ridge and 40 feet upstream of George Road Bridge. The barrier location is downstream of the farthest visible piece of munitions-related material that may have migrated from Rocket Ridge.

5. Executing Agencies

a. U.S. Army Corps of Engineers, Omaha District

6. Scope of Investigative/Characterization Action

a. The O&M phase of the Sand Creek Barrier System is focused on inspecting and removing the debris accumulated on the screen and assessing the integrity of the construction. This will be on a monthly basis.

b. Inspection of any MEC and Material Potentially Presenting an Explosive Hazard (MPPEH) found on the screen.

c. Storage and disposal of MEC and MD found on the screen.

7. Safety Criteria

a. The MEC that has been discovered, or is expected to be on site is 75-millimeter (mm) and 105-mm projectiles, booster cups, three 500-pound bombs, white phosphorus rifle grenades, fuzes, and burster tubes. The MGFD identified is the 500 lb Bomb M64A1. During the course of this investigative action, if MEC with a greater fragmentation distance is encountered, the MSD will be adjusted in accordance with DDESB Technical Paper 16, operations will continue, and an amendment to this ESP submitted for approval expeditiously.

b. See Table 7-1 for Minimum Separation Distances.

Notes:

1. See Figure 2 for calculation sheets and documentation of MSD. 2. Denotes MGFD during intrusive operation within the area indicated.

c. Any occupied buildings or public roadways in the MSD areas will be evacuated and/or roadways blocked to prevent non-essential personnel from entering during the conduct of intrusive investigations. There are no occupied buildings or public roadways in the MSD areas, see Figure 2.

d. The accumulated debris will be inspected for MEC/MD. Those items that are unfuzed and safe to move will be collected and placed in Igloo 1501 located at OD-2. If an item is fuzed or otherwise unsafe to move, the item will be BIP.

e. If a smaller MEC item is identified, demolition operations will be conducted using sandbag mitigation in accordance with (IAW) HNC-ED-CS-S-98-7, August 1998 and the DDESB Fragmentation Database if permitted in the publications.

f. Prior to initiating any disposal activities at RVAAP, the Contractor will submit the MEC Demolition/Disposal Notification to the Ohio EPA, as provided in the MEC Notification Procedure dated March 8, 2005 (Appendix C).

8. Methods of Disposal

a. A portable ATF approved Type 2, Class ABC magazine has been previously sited for proper storage of explosives at RVAAP. The magazine is sited inside explosive storage igloo 7-C-1 in the RVAAP C-Block explosives storage area (Figure 3). The portable magazine is provided lightning protection by the existing lightning protection system intended to protect the earth-covered magazine 7-C-1. The portable magazine is approximately 44” tall, with the earth-covered magazine being approximately 10’ tall. The lightning system for 7-C-1 extends approximately 3’ above the earth-covered magazine, and the grounding system for the Type II magazine is connected into the earth-covered magazine.



Ravenna, Ohio


b. The portable magazine will be used for the storage of both 1.1 and 1.4 class explosives to be used for demolition operations. All 1.1 and 1.4 explosives stored in the main body of the magazine will be of compatible storage categories. Blasting caps and other initiators used for demolition operations will be stored outside the magazine in the attached 18” x 18” x 18” “cap” box that is welded to the outside of the magazine. The NEW for the demolition material magazine will be a maximum of 100 pounds NEW (Figure 3).

c. An existing Earth Covered Magazine number 1501 located at ODA2 will be used for the storage of MEC that have been inspected by UXO-qualified personnel and determined to be “acceptable to move” (Figure 3). The ODA2 is a restricted explosives storage area within the RVAAP. Access to the ODA2 area is controlled through RVAAP Post 1 Security. The magazine will be afforded a lighting protection system IAW Department of the Army (DA) Pamphlet (PAM) 365-64.

d. The ESQD arc for intentional detonations when conducting BIP or disposal at ODA2 is 2,501 feet and is depicted in Figure 4.

9. Maps

Figure 1 shows the regional location of the Sand Creek Barrier within the Ravenna Army Ammunition Plant. Figure 2 depicts the Hazardous Fragmentation Distance around each investigation area. Figure 3 identifies the Inhabited Building Distance and Public Traffic Route Distance for the explosive storage magazines. Figure 4 identifies the Maximum Fragment Range – Horizontal (MFR-H) distance each area for the munition with the greatest fragmentation distance (MGFD).
