Range SustainabilityEnvironmental Program Assessments (RSEPA)4• Executes a range compliancemanagement process to ensure longtermsustainability using a phasedapproach▫ Ensures compliance with applicableregulations▫ Identifies and assesses potential for offrangemigration of munitions constituents(MCs) at land-based ranges• Provides a technically defensibleapproach for assessing theenvironmental condition of land-basedoperational ranges• Provides a framework for informeddecisions about when and how toproceed with a comprehensiveassessment and protective measures, ifnecessary

Range SustainabilityEnvironmental Program Assessments (RSEPA) Approach• Range Condition Assessment (RCA)▫ An RCA is conducted to determine if steps are necessary to maintaincompliance and to determine if further analysis is required to assess arisk of an off-range release. Review every five years.• Comprehensive Range Evaluation (CRE)▫ If further analysis is required after the RCA, a CRE will be conducted toverify and confirm if an off-range release of MCs has occurred or if thereis significant risk that an off-range release could occur. Conduct asneeded.• Sustainable Range Oversight During Off-Range ComprehensiveEnvironmental Restoration, Compensation, and Liability Act(CERCLA) Response (SRO)▫ An SRO is conducted in the event an off-range release has occurred.The focus of this phase is to ensure range sustainability is maintainedwhile proceeding through the CERCLA process for off-range releases.Conduct as needed.5

8San Clemente Island (SCI)• Southernmost of eight CaliforniaChannel Islands• 50 nautical miles (nm) south of LongBeach, Calif., and 68 nm (126kilometers) west of San Diego• Approximately 18 nm long and 4 nmacross at its widest point• Controlled by Navy since 7 November1934 under President Roosevelt’sExecutive Order• Land- and water-based ranges andoperations areas (OPAREAs)• Maritime setting and proximity tomainland make it ideally situated andfrequently usedW-291 (Special Use Airspace) too big to depictDue to its unique capabilities, SCI supports multiple training activities from every Navy Primary Mission Area(PMAR), and provides critical training resources for Expeditionary Strike Group (ESG), Carrier Strike Group (CSG),and Marine Expeditionary Unit (MEU) certification exercises

Summary of Land-BasedRanges with Munitions Usage• Special Warfare Training Areas (SWATs)▫▫▫▫Munition use limited to inert rounds and small quantities of explosives composition C4 and bulk2,4,6-trinitrotoluene (TNT)SWATs 1 through 6 used for Special Operations basic and advanced trainingDemolition practice on land takes place in the existing bermed demolition range in SWAT 2 and,occasionally, in SWAT 1Grenade explosions occur within a certified grenade range located in the Northwest Harbor area(SWAT 2)• Missile Impact Range (MIR)▫▫▫▫▫Developed as heavily instrumented, threat representative target set for research and developmentaltesting of missiles (for example, the Joint Standoff Weapon and the Tomahawk Land Attack Missile)Equipped with multiple camera stations to record impacts and detonations of weaponsContains fixed ground targets, including simulated structures and actual aircraftNo live munitions recorded fiscal year (FY) 01, FY02Space and Warfare Systems Command (SPAWAR) recovers missile remains after each shot• Shore Bombardment Area (SHOBA)▫▫▫Two impact areas for live-fire and inert ordnance training exercises for ships, aircraft, and groundforcesEncompasses almost 14,000 acres with over 3,000 acres designated as impact areas (more than2,000 acres for Impact Area I, 1,000 acres for Impact Area II, and 70 acres for the Bomb Box)Small arms, air-to-ground weapons, surface-to-surface weapons, ship-to-shore, and othercategories of munitions (such as surface-to-air, air-to-air)10

11Summary of Range Condition Assessment (RCA) – 2004• Ranges complied with environmental laws, regulations, and self-imposed military requirements with fewexceptions that were already in process of being addressed (for example, multi-year EnvironmentalImpact Statement)• Potential for migration from Special Warfare Training Areas (SWATs) 1 and 2, and Missile Impact Range(MIR) was considered unlikely▫ Limited munitions usage (few locations, limited quantities, few types) in the SWATs 1 and 2, and MIR▫ Predictive modeling not necessary• More munitions usage at Shore Bombardment Area (SHOBA)▫ Operational range site models (ORSMs) indicated greatest potential for migration from SHOBA▫ Predictive modeling was conducted in RCA▫ Predictive modeling in SHOBA showed potential for dissolved munitions constituents (MCs) to migrate toland-water interface via overland flow▫ Modeling assumptions were known to be overly conservative (for example, concentrations at solubility limits,little/no degradation or adsorption), but there was no way to quantify the degree of conservatism or reduce theconservatism without additional data collection▫ Navy decisions: (1) site-specific media sampling in SHOBA to be collected during five-year review to providemore data to evaluate off-range migration potential and (2) policy revision needed to require predictive modelvalidation if concern is NOT identifiedAdditional challenges for RCA at the time – Range Sustainability Environmental Program Assessments (RSEPA) policydevelopment was in early phase and no other RCAs were completed or under way

13Summary of Five-Year Review• Collected 35 multi-incremental surface soil and five discrete surface water samples from Shore BombardmentArea (SHOBA) in March 2007 and analyzed all samples for perchlorate (SW6850) and explosives (SW8330B)• Collected samples from various points inerosion channels running through SHOBAand into Pacific Ocean to determine ifmunitions constituents (MCs) are migrating toland/water interface• Collected soil samples from the upper 2inches or water samples from standing pools• More sampling in Impact Area II than inImpact Area I due to access/safety issues,but Impact Area II used more heavily thanImpact Area I (therefore, bias seemsappropriate)• Ensured sampling included down-gradientfrom Bomb Box and at land/water interfaceChallenges for sampling included presence of sensitive munitions, hazardous work environment,restricted work schedules, limited accessibility, and transportation/shipping constraints

14Summary of Five-Year Review (cont’d)• Only seven munitions constituents (MCs) were detected: 2,6-dinitrotoluene (DNT);octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX); nitrobenzene; nitroglycerin; perchlorate;hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX); and 2,4,6-trinitrotoluene (TNT)• Only HMX was detected in any water sample and only detected in one sample (not detected in duplicate)• Primary spatial trend observed in results was explosives detected in up- and mid-gradient sample locationswith degradants detected in mid- and down-gradient sample locations (natural attenuation)▫ More compounds detected in samples collected at the land/water interface than mid- and up-gradient▫ Many of compounds detected at the land/water interface were degradation products▫ No explosives detected in samples downstream from the Bomb Box at the land/water interface, suggestingeither complete degradation and/or limited mobility in the erosion channelMost explosives weredetected in SC-S-05Location SC-S-36 wasnear the land-oceaninterfaceLocation SC-S-32illustrates all of thesampling incrementsLocationSC-SW-04 shows thetypical amount ofstanding water inchannelsSC-SW-01 was takenfrom this natural poolSample SC-S-14 wastaken in mid-gradientzoneAll detected concentrations fall below action levels established in the Field Sampling Plan
