USA AAR–100% Grid Sampling/4' OE Removal- Site OE-53, Former Fort Ord, CA 

Final: 30 September 2001 

Statement of Explanation 

The work, which was accomplished on this site, was performed by CMS Environmental, Inc. (CMS) 

which was the UXO contractor on Fort Ord from August 1995 through September 1998. In June of 

1998 CMS was sold and the name of the company became USA Environmental, Inc. (USA). In July 

1998 USA began to conduct work on Fort Ord as a sub-contractor to CMS. In September the novation 

was complete and USA became the prime contractor for Contract Number DACA 87-96-D-0019. 

One of the results of this change is that USA is now reporting on work performed by CMS. The one 

noticeable difference and apparent inconsistency is the use of “USA” in the headers for each page, 

while “CMS” is referenced in the text. This disparity is unavoidable, as USA Environmental did not 

exist when these operations were being performed and CMS Environmental now no longer exists on 

Fort Ord.

Chapter 1: Overview 

1.0 INTRODUCTION 

An Ordnance and Explosive (OE) grid sampling and a four (4) foot removal action was completed on 

Site OE-53 (EDC) with the objective of removing all UXO items from the site to a depth of at least 

four (4) feet where such items could be detected from the surface using magnetometers. Site OE-53 

(EDC) (formerly know as Shoulder Launched Projectile Area) is located north of the Multi-Range 

Area (MRA) between Parker Flats Road and Parker Flats Cut-off. Site OE-53 (EDC) is identified in 

the Final Phase 2 Engineering Evaluation/Cost Analysis (EE/CA) (April 1998) as Land Use Group III, 

Institutional/public, commercial, industrial, residential and as such may be subject to additional 

development in the future. Site OE-53 (EDC) encompasses approximately three hundred ten (310) 

acres and is rated medium for both terrain and vegetation difficulty. Figure 1-1 shows the boundaries 

of Site OE-53 (EDC) and figure 1-2 on the following page shows the location of this map within the 

former Fort Ord.

1.1 AUTHORITY 

CMS was tasked under Contract Number DACA87-96-D-0019 Task Order 0004 to perform vegetation 

removal, perimeter survey, 100% grid sampling, survey and 4' OE removal from OE-53 (EDC). The 

Sacramento District Office of the U.S. Army Corps of Engineers (CESPK) administered this contract. 

Work under Task Order 0004 commenced in June of 1998 (survey). Authority for these operations is 

as follows: 

(a) The work performed under this task order falls under the authority of the Base Realignment and 

Closure Act (BRAC) and was executed to search for ordnance and explosives (OE) that 

constituted an imminent and substantial endangerment to the local populace and site personnel. 

(b) Department of Defense (DoD) is the removal response authority with respect to incidents involving 

DoD military weapons and munitions or weapons and munitions under the jurisdiction, custody or 

control of DoD as identified by 40 CFR Section 300.120(d). 

(c) These actions are consistent with the Comprehensive Environmental Response, Compensation and 

Liability Act (CERCLA), section 104 and the National Contingency Plan, sections 300.400(b) and 

300.400(c) 

(d) Consistent with the above, no Federal, State or Local permits were required nor were obtained for 

the detonation of UXO on-site. 

(e) The provisions of 29 CFR 1910.120 (OSHA Hazardous Waste and Emergency Operation) apply to 

this site.

1.2 HISTORY OF ORDNANCE AND EXPLOSIVE USE IN THE SITE 

The following information was obtained from the Revised Archives Search Report (ASR). Shoulder 

Launched Projectile Target Area “C”. The hill, located between the two flats, was a target area for the 

rifle grenades and shoulder-launched projectiles. The firing points were near a small building across 

the flat to the west. The hill was also assaulted by rifle grenades and shoulder launched projectiles 

form the east. This use occurred in the 1940’s, 1950’s, and 1960’s. The hill south of the large flat at 

Parker Flats was a target area for rifle grenades and ground/tube launched projectiles. The firing point 

was near the road on the northeast side of the flat. The main target was a tank hull placed at the 

intersection of two roads. This use occurred in the 1940’s, 1950’s, and 1960’s. A site inspection in 

May of 1996, USACE OE Safety Specialist discovered one 3” Stokes mortar with unknown filler. A 

second visit revealed 75mm fragments, two 3” Stokes mortars and unidentified projectile 

fragmentation.

Chapter 2: Operation Approach 


This chapter provides a description of the specific activities involved in meeting the requirements of 

the Work Plan as it applies to Site OE-53. Results of daily operations are recorded in Daily Operations 

Journals, included in this report as Appendix I. Grid Operations Records are included as Appendix J. 

Relevant portions of this Work Plan are included in this report as Appendix F. 

2.1 SITE VISIT AND SITE–SPECIFIC WORK PLAN 

A site visit was conducted by CMS on June 5-9, 1995. The Site-Specific Work Plan (July 21, 1995) 

makes no mention of Site OE-53, but states, “Other sites determined to be contaminated as the result of 

on-going OE sampling on Fort Ord can be added or substituted for cited acreage as information 

becomes available.” 

2.2 COMMUNITY RELATIONS 

USA has not received any requests for community relation’s activities in relationship to Site OE-53. 

2.3 LOCATION SURVEYS AND MAPPING 

Surveying activities commenced on June 2, 1998 on Site OE-53 using global positioning system 

(GPS). The total area of Site OE-53 (310.30 acres) contains one thousand three hundred fifty-seven 

(1357) 100’ by 100’ grids and partial grids. The survey team commenced staking fifty-two (52) 100' X 

100' grids for 100% grid sampling. The northern most boundary of Site OE-53 was established on 

February 4, 2000. By April 3, 2000, the entire site was completed and all grids were staked. Work 

Plan procedures for surveying and mapping are included in Appendix F. Planimetric maps are 

included in Appendix E. 

2.4 BRUSH CUTTING OPERATIONS 

Due to the heavy vegetation density on Site OE-53, mechanical vegetation removal was required on 

most of these grids. Manual brush cutting techniques using chainsaws and rotary trimmers were 

incorporated to compliment the mechanical operations in the heavily wooded areas. Brush cutting 

began on June 2, 1998 and continued through April of 2000. Procedures for mechanical and manual 

brush cutting procedures are listed in Appendix F, Work Plan Excerpts. 

2.5 PRIOR SAMPLING OPERATIONS 

The revised ASR (1997) states that this site has not been investigated as of this time. 

2.6 RESULTS OF WORK PERFORMED BY CMS/USA ENVIRONMENTAL 

Two separate phases of work were performed on Site OE-53: 

(a) 100% grid sampling 

(b) 4' OE removal 

Each phase will be discussed in detail as a distinct operation in the following sections. A listing of 

UXO encountered during each phase is listed in tabular form in the corresponding subparagraph of this 

section. A complete site listing of UXO and OE scrap is presented in Appendix C. 


Page 2-1



2.6.1 100% GRID SAMPLING 

100% grid sampling, to a depth of 4 ft below ground surface (bgs) was performed on fifty-two (52) 

100' X 100' grids on Site OE-53. This phase of the work started on June 10, 1998 and was completed 

on September 21, 1998. Six hundred sixteen (616) occurrences OE or OE scrap items were recovered 

from forty-seven (47) of the fifty-two (52) sample grids. Nineteen (19) items recovered contained 

energetic material or hazardous components. Scrap removed from these fifty-two (52) grids was 

comprised of 453 pounds of OE scrap and 841 pounds of non-OE scrap. UXO recovered during the 

100% grid-sampling phase is listed in Table 2-1 below:

2.6.2 FOUR FOOT OE REMOVAL OPERATIONS 

A decision was made by the government to conduct a 4' OE removal operation on the site. USA started 

four (4) foot OE removal operations on the remaining one thousand three hundred and five (1,305) 

grids beginning in September of 1998. Work was completed in December 2000. A total of twelve 

thousand eighty-six (12,086) occurrences of UXO/OE scrap were encountered on these grids OE Scrap 

11,584 Pounds/Non-OE Scrap 27,180 Pounds. One thousand two hundred ninety-one (1,291) 

contained energetic material or hazardous components. As the original five hundred and twenty two 

(522) 4’ OE Removal grids inside OE-53 were completed a protocol was developed by USA 

Environmental Inc. to be used by USACE SPK as an interim guidance on following the OE on the 

edge of a completed site. The protocol involved additional removal/sampling for 200 ft beyond the 

location of Projected ordnance items and 100 ft beyond all thrown or placed ordnance items. This 

protocol considered significant discovery of OE related scrap as a reason for additional 

removal/sampling of the surrounding area. This “Follow the OE” protocol added an additional 192.30 

acres to the original size of OE-53. The removal effort ceased when contact with boundary OE-50 to 

the west; BLM land to the east; the Multi Range Area to the south; and an arbitrary line to cease 

operations to the north was designated by the USACE SPK. A description of these items is listed in

2.7 DEMOLITION OPERATIONS 

UXO items encountered at Site OE-53 were destroyed by CMS/USA using demolition procedures. 

There are two categories of UXO items which may be encountered: 1) items with energetic materials 

or hazardous components unsafe to move which are therefore detonated where found and 2) items with 

energetic materials and hazardous components deemed safe to move which were relocated to a safe 

holding area until consolidated demolition shots were scheduled. Consolidated demolition shots to 

dispose of UXO from the safe holding area were held at Range 45 and in the fuel break, areas of 

former Fort Ord used for demolition operations because they are sufficiently remote from dwellings, 

the terrain affords good visibility for the demolition team and the areas are less likely to be subject to 

intruders because of their locations inside the fenced Multi-Range Area (MRA). UXO items from Site 

OE-53 were also destroyed in demolition operations in Sites OE-37, OE-10A, OE-44 and OE-42. 

Explosives Usage Records from the OE database related to the destruction of the UXO from Site OE- 

53 are included in this report as Appendix G. All demolition was accomplished as specified in the 

Work Plan and described in Appendix F of this report. 

2.8 ORDNANCE SCRAP AND OTHER SCRAP RECOVERED 

Ordnance scrap is defined as a military munition or components thereof, which contain no explosive, 


Page 2-5



pyrotechnic or chemical agent. These can be, but are not limited to, practice munitions without 

spotting charges, drill rounds, inert training munitions or expended ejection munitions. Fragments of 

military munitions, which have functioned as designed or were recovered from areas where munitions 

have been intentionally destroyed, are ordnance scrap if they have no explosive, pyrotechnic or 

chemical filler. These items pose no imminent threat to public safety but may require venting or some 

other action prior to release from government control. Table 2-3 below lists, in pounds, both ordnance 

(OE) scrap and non-ordnance scrap (nails, cans, fence posts etc.) recovered from Site OE-53. Table 2-4 

describes OE scrap (fragments) items recovered and recorded by weight (pounds). Table 2-5 lists OE 

scrap items recorded by quantity (each). Appendix H addresses the disposition of the ordnance scrap.

2.9 QUALITY ASSURANCE AND QUALITY CONTROL TESTS 

Throughout operations at Site OE-53 CMS and USA performed daily operational checks and Quality 

Control (QC) inspections of its work. Procedures for quality control are specified in the Work Plan 

included as Appendix F. No deficiency reports were written during inspections of the work done in 


Page 2-11



Site OE-53. Quality Control and Quality Assurance inspections for the 100% sample grids and 4' OE 

removal grids are located in Appendix K and L respectively. 

2.10 ANALYSIS OF EFFECTIVENESS 

Information extracted from the ASR and the USACE OE Safety Specialist site visit accurately 

forecasted the ordnance types encountered at Site OE-53. While a variety of ordnance types were 

ultimately found on the site as predicted by this data, all UXO and ordnance scrap recovered from Site 

OE-53 was compatible with information provided in these documents. The design UXO (the deepest 

penetrating ordnance type found by on-site investigators) for Site OE-53 is recorded in the April 1998 

Phase II EE/CA as a 37mm projectile (the EE/CA Phase II referenced the M48 75mm projectile, which 

can be expected to penetrate up 4.9' in sand. Types found on this site were the 75mm Mk 1, shrapnel 

projectiles). Comparison data presented in this report references the M48 as no data is presented for 

the Mk1 shrapnel version of this item. Note 1 in Table 2-6 states that the deepest detection depth at the 

former Fort Ord is 3.9’ for the 75mm Shrapnel MK1. Both 75mm and 37mm projectiles are believed 

to penetrate deeper than can be detected using the Schonstedt GA-52Cx magnetic locator. Table 2-6 

below lists the calculated penetration capabilities of ordnance recovered from Site OE-53 and the 

estimated depth at which the ordnance may be expected to be found using the Schonstedt GA-52Cx 

magnetic locator.

2.11 CONCLUSIONS 

USA was able to confirm the ASR that rifle grenades and tube-launched projectiles used in OE-53. 

The location of firing points could not be determined. The two (2) phases of UXO remediation 

conducted on Site OE-53 are complete. Ordnance and ordnance scrap was removed from the fifty-two 

(52) 100' X 100' sampling girds accomplished in September 1998. These grids were investigated to 

four (4) feet bgs by the use of GA-52Cx Schonstedt Flux Gate Magnetometer. Nineteen (19) instances 

Page 2-12



of UXO were recovered from these sample grids. 

The remainder of the one thousand three hundred and five (1,305) grids on OE-53 was investigated to 

four (4) feet bgs beginning September 1998. This effort produced one thousand three hundred twentynine 

(1329) occurrences of UXO and eleven thousand seven hundred sixty-one (11761) instances of 

OE scrap. OE scrap removed from site OE-53 was comprised of a variety of munitions used for troop 

training and fragments of 37mm and 75mm projectiles, 60mm, 81mm mortars and Levins Projectors. 

Because some of the ordnance scrap on this site appears to have been placed or buried, (such as live 

and expended pyrotechnics found 36"-48" bgs), it is possible that buried or placed UXO/OE scrap may 

still exist on Site OE-53. 

Looking at the data USA Environmental Inc. has published, in Cost and Schedule Reports, the OE 

Database and the Contract Closure Report can render a professional opinion. 

Penetrated Ordnance: 

1. 92% of the 75mm M49 either the HE or Common M1 version were found within 24" of the surface. 

2. The Schonstedt was able to locate projectiles down to a maximum depth of MK1 Shrapnel at 30" 

(one inch deeper than the Huntsville Penetration Study) and MK 1 Common at 48" in (sand) which is 

(deeper 19" deeper than the Huntsville Penetration study). 

3. 91% of all Shrapnel projectiles recovered were expended. This seems to reflect a very high 

percentage function as designed. 

4. We have found UXO Shrapnel Projectiles down to 30" below ground surface and expended 

shrapnel projectiles down to the same level. 

When the Ordnance Detection and Discrimination Study (ODDS) is reviewed for which instruments 

were effectively locating items in the first 24" (which is where the majority of UXO and OE scrap is 

located) the Schonstedt was rated as one of the best. 

2.12 RECOMMENDATIONS 

It is the evaluation of USA management personnel in consultation with USACE OE Safety Specialists 

that the existence of buried UXO within the site is possible. The results of this OE removal effort on 

Site OE-53 support the following recommendations: 

(a) In view of the extent of the investigation and removal efforts conducted on this site, the 

demonstrated ability of UXO Technicians to detect and remove deeply buried munitions, and 

comparing maximum penetration data with USA's OE database for the penetrating ordnance 

located on Site OE-53, it is unlikely that penetrating ordnance exists on this site. 

(b) The presence of buried ordnance located on the site at depths to 48" dictates the possibility exists, 

(but is considered unlikely), for more occurrences of deeply buried ordnance which is beyond the 

detection capabilities of the Schonstedt GA-52Cx. Therefore further investigation using the same 

technology would be ineffective. 


Page 2-13



(c) It is the opinion of this contractor that, taking into account the extensive sampling and intrusive 

activities conducted in this site, this action has resulted in a high degree of certainty that no further 

OE response is needed if current and planned reuse does not require intrusive activities below the 

four foot (4’) clearance depth. If the reuse of the property does require activities below the 4’ 

clearance depth it is the recommendation of the contractor to have a UXO construction support 

team on stand by during the intrusive operations, or to bring in technologies that have the 

capabilities of detecting anomalies at depth greater than 4’ bgs. 

(d) Due to the extent of removal efforts in the north, south and the east of site OE-53 and the sampling 

conducted in MOCO-2 and clearance of OE-44 EDC there is a strong indication that penetrating 

ordnance could be beneath the surface of Parker Flats Road and Eucalyptus Road bordering Site 

OE-53. It would be the contractor’s recommendation that the Government use a technology that is 

capable of investigating the potential of anomalies below the surface of the road.

Chapter 4: Recapitulation 


The 100% grid sampling, and four (4) foot OE removal action on Site OE-53 was accomplished by 

CMS and USA Environmental Inc. between June 1998 and November 2000. Authorization was 

provided under Task Order 0004 under Contract Number DACA87-96-D-0019. This chapter 

recapitulates the information contained in this report and describes the specific lessons learned during 

this operation. 

4.1 RECAPITULATION OF THE REPORT 

4.1.1 SITE DESCRIPTION 

Site OE-53 is located north of The MRA between Parker Flats Road and Eucalyptus Road. At the time 

of the sampling and OE removal actions, the site encompassed approximately three hundred ten (310) 

acres. Site OE-53 is identified in the Final Phase 2 Engineering Evaluation/Cost Analysis (EE/CA) 

(April 1998) as Land Use Group III, Institutional/public, commercial, industrial, residential and as 

such may be subject to additional development in the future. 

4.1.2 PRIOR SAMPLING RESULTS 

The 1997 Revised Archive Search Report (ASR) states that Site OE-53 has not been investigated as of 

this time. Based upon a site inspection conducted on the site by an USACE OE Safety Specialist. OE 

items located on the site included 75mm projectile shrapnel and 3” Stokes Trench Mortars. 

4.1.3 PARAMETERS OF SAMPLING 

CMS performed 100% grid sampling on fifty-two (52) 100' X 100' grids in June 1998. This action was 

completed by USA in June 1998 with nineteen (19) occurrences of UXO containing energetic 

materials being located. 

USA Environmental performed additional expansion sampling on two hundred and thirty-six (236) 

surrounding the northern most sample grids. This 4' removal of grids was cleared by USA in March 

and April 1999. Twenty-three (23) UXO items were located and destroyed during subsequent 

demolition operations, conducted mainly on Range 43. One item was blown in place as it was deemed 

unsafe to move to another disposal site. 

4.1.4 BRUSH REMOVAL OPERATIONS 

Vegetation removal operations required for Site OE-53 were accomplished by mechanical and manual 

brush cutting crews. CMS/USA subcontractor, Timberline Logging, provided mechanical brush 

cutting. Manual cutting was accomplished by a team of laborers escorted by a UXO Technician 

provided by CMS and USA. 

4.1.5 100% GRID SAMPLING OPERATIONS 

Fifty-two (52) 100' X 100' grids were 100% investigated between June 25, and June 23, 1998. 

Nineteen (19) instances of UXO were reported from these grids and four hundred fifty-three (453) 

pounds of fragments or pieces of ordnance scrap was located and removed. Eight hundred and forty-

one (841) pounds of OE scrap and non-ordnance scrap respectively was collected and removed from 

these grids. 

4.1.6 FOUR FOOT OE REMOVAL 

During the four (4) foot OE removal phase of this action, which entailed investigating a total of twelve 

thousand eighty-six (12,086) occurrences of UXO/OE scrap that were encountered within site OE-53. 

One thousand two hundred ninety-one (1,291) contained energetic material or hazardous components. 

Scrap collected and removed consisted of eleven thousand three hundred eight-four (11,384) pounds of 

OE scrap, and twenty seven thousand and one hundred and eighty (27,180) pounds of non-OE scrap. 

The total scrap removed during these two phases is eleven thousand eight hundred thirty-seven 

(11,837) pounds of OE scrap and twenty eight thousand and twenty one (28,021) pounds of non-OE 

scrap. 

4.1.8 SUMMARY OF COSTS 

This total cost of these two (sampling/removal) actions at Site OE-53 was $64,137.47 for the sampling 

effort and $753,941.05 for the four (4) foot removal. Seventy one thousand, three hundred twenty-four 

(71,324) personnel-hours were devoted to this site. 

4.1.9 SUMMARY OF RECOMMENDATIONS 

It is the evaluation of USA management personnel in consultation with USACE OE Safety Specialists 

that the existence of buried UXO within the site is possible. The results of this OE removal effort on 

Site OE-53 support the following recommendations: 

(a) In view of the extent of the investigation and removal efforts conducted on this site, the 

demonstrated ability of UXO Technicians to detect and remove deeply buried munitions, and 

comparing maximum penetration data with USA's OE database for the penetrating ordnance 

located on Site OE-53, it is unlikely that penetrating ordnance exists on this site. 

(b) The presence of buried ordnance located on the site at depths to 48" dictates the possibility exists, 

(but is considered unlikely), for more occurrences of deeply buried ordnance which is beyond the 

detection capabilities of the Schonstedt GA-52Cx. Therefore further investigation using the same 

technology would be ineffective. 

(c) It is the opinion of this contractor that, taking into account the extensive sampling and intrusive 

activities conducted in this site, this action has resulted in a high degree of certainty that no further 

OE response is needed if current and planned reuse does not require intrusive activities below the 

four (4) foot clearance depth. If the reuse of the property does require activities below the 4’ 

clearance depth, it is the recommendation of the contractor to have a UXO construction support 

team on standby during the intrusive operations, or to bring in technologies that have the 

capabilities of detecting anomalies at depth greater than 4’. 

(d) Due to the extent of removal efforts in the south and the west of site OE-53 and the sampling 

conducted in MOCO-2 and clearance of OE-44 EDC there is a strong indication that penetrating 

ordnance could be beneath the surface of Parker Flats Cutoff and Eucalyptus Road bordering Site

OE-53. It would be the contractor’s recommendation that the Government use a technology that is 

capable of investigating the potential on anomalies below the surface of the road. 

Looking at the data USA Environmental Inc. has published, in Cost and Schedule Reports, the OE 

Database and the Contract Closure Report can render a professional opinion. 

Penetrated Ordnance: 

1. 92% of the 75mm M49 either the HE or Common M1 version were found within 24" of the surface. 

2. The Schonstedt was able to locate projectiles down to a maximum depth of MK1 Shrapnel at 30" 

(one inch deeper than the Huntsville Penetration Study) and MK 1 Common at 48" in (sand) which is 

(deeper 19" deeper than the Huntsville Penetration study). 

3. 91% of all Shrapnel projectiles recovered were expended. This seems to reflect a very high 

percentage function as designed. 

4. We have found UXO Shrapnel Projectiles down to 30" below ground surface and expended 

shrapnel projectiles down to the same level. 

When the Ordnance Detection and Discrimination Study (ODDS) is reviewed for which instruments 

were effectively locating items in the first 24" (which is where the majority of UXO and OE scrap is 

located) the Schonstedt was rated as one of the best.
