Agent Orange Storage Sites United States and Presumptive Rules
Military service at domestic bases where tactical herbicides were tested or stored can support a disability claim, but that service is generally not automatically presumptive like active duty in Vietnam. At Rank and Pay, we examine the evidentiary criteria established by the Department of Veterans Affairs (VA) so you know what service records and medical documentation your claim requires before filing. Veterans seeking benefits for herbicide exposure at these domestic installations must meet rigorous evidentiary standards.
This guide is not for veterans who served boots on the ground in the Republic of Vietnam or in covered inland waterways, as those veterans qualify under standard statutory presumptions and should consult our VA Agent Orange exposure guide instead. Congress or the VA could expand statutory presumptions to cover domestic testing locations automatically in future legislation, which would eliminate the requirement for individual exposure records and medical nexus opinions.
Under federal regulations, presumptive service connection allows qualifying veterans to bypass the requirement to prove that an in-service incident caused their current medical disability. When a veteran has documented service in Vietnam, Thailand, or designated offshore waters, the law concedes chemical exposure automatically. That statutory concession does not extend to domestic installations. If you served at one of these domestic testing or storage installations, you must establish direct service connection by submitting affirmative evidence of chemical contact.
Confirmed Testing and Storage Locations
Official Department of Defense (DoD) records identify specific military installations where tactical herbicides were tested, used, or stored outside the primary combat theater in Vietnam. The Department of Veterans Affairs publishes this historical inventory on its public health website to assist adjudicators and veterans evaluating toxic exposure claims. Veterans should avoid unofficial third-party summaries that claim an exact total count of installations, because relying on unverified base names can lead to wasted claims and procedural denials.
Domestic Facilities on the Department of Defense Inventory
Documented domestic herbicide projects took place under controlled testing, training, and logistical operations at selected installations across the country. Sourced Department of Defense records confirm operational handling at two specific mainland locations:
- Fort Chaffee, Arkansas: Official military records document tactical herbicide testing conducted on specific dates in 1967. Personnel stationed at the installation during those exact dates can use those published records to document that chemical testing occurred during their period of service.
- Port of Mobile, Alabama: The military operated the U.S. Army Gulf Outport at the Port of Mobile as an official logistical transshipment point. Department of Defense documentation verifies herbicide storage and shipping operations at this facility between 1965 and 1968.
The authoritative roster of locations, testing dates, and chemical formulations is maintained on the official VA domestic herbicide test and storage list. You should check your military personnel records against that published directory rather than relying on unofficial summaries.
Johnston Island Storage after Operational Removal
Tactical herbicide inventories were also transported and stored at locations outside both the continental United States and the Republic of Vietnam. Following the conclusion of operational spraying in Southeast Asia, the Department of Defense relocated remaining chemical stocks to Johnston Island on Johnston Atoll in the Pacific Ocean. Sourced records confirm that herbicide barrels were stored and maintained on Johnston Island between approximately 1972 and 1977. Veterans who served on Johnston Island during that operational period have documented proof that tactical herbicides were present on the installation.
For verified installations located in overseas territories and international stations outside Vietnam, consult the VA list of herbicide tests and storage outside Vietnam. You can also examine the broader Department of Defense research records on the VA herbicide tests and storage overview.
Evidence Requirements for Agent Orange Storage Sites United States Claims
Direct service connection for herbicide exposure at domestic military installations requires three distinct elements of evidence. Because domestic locations do not qualify for statutory exposure concessions, an adjudicator must review your submission under general service connection rules. Missing any single component will result in a formal denial.
- Verified presence during operational dates: You must provide military personnel records, travel orders, or unit morning reports confirming that you were physically assigned to the base during the exact dates documented in the dod herbicide test sites list. Being assigned to an installation months before testing commenced or years after storage barrels were removed does not establish chemical exposure.
- A current medical diagnosis: You must have a formal, documented medical diagnosis of a chronic medical condition or physical disability. The diagnosis must be active and established through competent clinical records.
- A medical nexus opinion: You must provide a written opinion from a qualified medical provider establishing a causal link between your diagnosed condition and chemical exposure at the domestic facility. The letter should state that it is at least as likely as not that your condition resulted from herbicide contact during your military duties. Review our VA nexus letter guide for detailed instructions on structuring this clinical opinion.
Presumptive Conditions and Title 38 Regulations
Title 38 of the Code of Federal Regulations (CFR) defines the medical conditions that federal health authorities associate with tactical herbicide exposure. Under 38 CFR § 3.309, the VA recognizes specific cancers, type 2 diabetes mellitus, Parkinson's disease, ischemic heart disease, and peripheral neuropathy as scientifically linked to herbicide agents. When evaluating agent orange exposure outside vietnam, having a diagnosis for an illness recognized in 38 CFR § 3.309 strengthens the clinical foundation of your claim.
However, the regulatory list does not replace the requirement for individual proof of exposure. When a claim involves a domestic storage installation, the adjudicator uses 38 CFR § 3.309 to confirm biological plausibility, but the veteran must still substantiate physical presence and medical causation. To learn how federal authorities continue to update recognized conditions, review our guide to PACT Act presumptive conditions and the Agent Orange 2026 additions.
Comparison of In-Country Presumptions and Domestic Exposure Claims
The evidentiary burden for domestic herbicide exposure claims is substantially higher than the standard applied to in-country Vietnam veterans. Understanding how statutory categories differ helps prevent procedural misunderstandings when preparing your submission.
| Claim Category | Exposure Presumption | Required Service Documentation | Medical Nexus Requirement |
|---|---|---|---|
| Vietnam In-Country and Territorial Waters | Conceded automatically by federal statute | DD-214 or personnel orders showing service within borders or territorial seas | Not required for conditions recognized under 38 CFR § 3.309 |
| Domestic Test and Storage Installations | Not presumptive; direct connection required | Personnel records proving physical presence during exact DoD project dates | Mandatory medical opinion linking diagnosis to installation exposure |
| Johnston Island Herbicide Storage Site | Not presumptive; direct connection required | Service records proving assignment to Johnston Island between 1972 and 1977 | Mandatory medical opinion linking diagnosis to storage facility duties |

Documenting Claims for Agent Orange Storage Sites United States Installations
Assembling a direct service connection claim for domestic herbicide exposure requires methodical compilation of your military service history. Follow these administrative steps before filing your application:
- Retrieve your Official Military Personnel File (OMPF): Request your complete military personnel file from the National Archives, including duty assignment records, unit morning reports, performance evaluations, and temporary duty travel vouchers.
- Cross-reference official project dates: Compare your service dates against the verified operational windows published on the official VA domestic herbicide test and storage list. Confirm that your unit was physically present during documented testing or storage operations.
- Gather civilian and VA treatment records: Secure complete clinical documentation establishing an active medical diagnosis for your condition.
- Provide documentation to your medical provider: Give your treating physician copies of your verified service records and the published Department of Defense testing documents. Ask your provider to evaluate the chemical toxicity of the specific herbicides tested.
- Secure an independent nexus evaluation: Request a written medical opinion addressing whether chemical exposure during your domestic assignment contributed to your current condition.
- Submit your application: Complete VA Form 21-526EZ, attaching your service timeline, the relevant Department of Defense test records, your clinical diagnosis, and your medical nexus letter.
Common Mistakes in Domestic Herbicide Claims
Filing a domestic herbicide claim without matching exact testing dates represents the most frequent cause of claim denials. Adjudicators evaluate these cases strictly against military history logs.
- Assuming base assignment alone establishes exposure: Military bases cover expansive areas. Being stationed at Fort Chaffee outside the specific testing dates in 1967 does not substantiate chemical contact.
- Submitting a claim without a medical nexus letter: Many veterans assume that submitting a diagnosis for an illness listed in 38 CFR § 3.309 is sufficient on its own. Without an affirmative medical opinion connecting that condition to domestic base duties, the VA will deny service connection.
- Confusing generic industrial waste with tactical herbicides: Many military installations had burn pits, industrial solvent dumps, or fuel spills. While hazardous, those materials do not constitute tactical herbicide exposure and must be claimed under separate toxic exposure provisions.
