Portsmouth Naval Shipyard Toxic Exposure and the PACT Act

Portsmouth Naval Shipyard toxic exposure claims involving asbestos do not qualify for presumptive service connection under the PACT Act and must proceed through the direct service connection pathway. At Rank and Pay, we examine military records and statutory guidelines to help veterans navigate Department of Veterans Affairs (VA) claims accurately. If you served at Portsmouth Naval Shipyard, establishing service connection requires showing a current diagnosis, verified in-service exposure, and a medical nexus linking the two.

Many veterans assume that recent toxic exposure legislation created automatic coverage for shipyard duty. The Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics Act of 2022, known as the PACT Act, expanded presumptive conditions for burn pits, Agent Orange, and other specific airborne hazards. The PACT Act did not add a statutory presumption for asbestos-related illnesses.

Veterans who served at shipyards cannot rely on geographic location alone to establish a service connection for asbestos disease. You must pursue direct service connection under standard VA disability regulations. For a broader overview of statutory presumptions, review our guide to PACT Act eligibility and the main PACT Act resource hub.

History of Toxic Materials at Portsmouth Naval Shipyard

Portsmouth Naval Shipyard (PNSY) sits on Seavey Island in the Piscataqua River between Kittery, Maine, and Portsmouth, New Hampshire. Established in 1800, the installation represents one of the oldest continuously operating shipyards in the United States Navy. Over the past century, the shipyard has specialized in submarine construction, overhaul, and scheduled maintenance.

During peak World War II operations, Portsmouth Naval Shipyard employed roughly 23,000 workers and built more than 78 submarines. Throughout this era and subsequent decades, shipbuilders and military personnel routinely handled asbestos. The material served as standard thermal insulation for boilers, steam pipes, gaskets, deck coverings, and fireproofing bulkheads due to its heat resistance and low manufacturing cost.

Submarines feature tight, enclosed compartments with shared ventilation systems. Whenever maintenance teams removed or replaced thermal insulation, microscopic asbestos fibers entered the ambient air. Service members working in reactor spaces, auxiliary rooms, propulsion plants, and living quarters inhaled or ingested these durable mineral fibers.

Why Asbestos Claims Require Direct Service Connection

Direct service connection requires affirmative proof that an in-service event caused your current medical condition. Because asbestos exposure lacks a statutory presumption, VA does not assume your condition arose from military service. The burden of proof rests on the claimant to connect their present diagnosis to documented shipyard duties.

Asbestos-related diseases feature long latency periods, often taking 20 to 50 years to produce symptoms. This delayed onset means most veterans receive diagnoses decades after leaving military service. Because of this gap, VA scrutinizes post-military employment histories to see if civilian work could explain the condition.

A successful direct service connection claim bridges that multi-decade gap with medical rationale. You must demonstrate that your military exposure at the shipyard was at least as likely as not the cause of your pulmonary illness.

VA Adjudication Under the M21-1 Manual

VA claims adjudicators process asbestos claims using specific administrative procedures. These rules are codified in the M21-1 Adjudication Procedures Manual, Part VIII, Subpart iii, Chapter 7, Section B, titled "Development and Examination Requests for Claims Based on Exposure to Asbestos."

The M21-1 manual directs the claims processor to determine whether military records show credible evidence of in-service asbestos exposure. The processor must examine your military occupational specialty, specific vessel assignments, and facility duties at Portsmouth Naval Shipyard. Adjudicators also evaluate whether your pre-service or post-service civilian jobs involved asbestos exposure.

Finally, the manual instructs processors to weigh the latency period when developing the claim for a medical examination. If service records establish exposure and latency fits known medical timelines, the processor orders a Compensation and Pension (C&P) examination. The examining medical examiner must address whether the military exposure caused or contributed to the current disease.

VA Diagnostic Codes and Disability Ratings for Shipyard Exposure

VA rates asbestos-related conditions under Title 38 of the Code of Federal Regulations (38 CFR § 4.97). Each respiratory condition maps to a specific Diagnostic Code (DC) with distinct rating criteria.

Mesothelioma and Lung Cancer (Diagnostic Code 6819)

Mesothelioma and lung cancer receive evaluation under Diagnostic Code 6819, which covers malignant neoplasms of the respiratory system. Active malignancies under Diagnostic Code 6819 receive an automatic 100 percent disability rating.

This 100 percent rating continues during active disease and throughout any ongoing treatment, including chemotherapy, radiation, or surgical recovery. Following the completion of active treatment, VA schedules a mandatory re-examination. If the malignancy enters remission, VA re-evaluates the condition based on any lingering respiratory impairment. Learn more about rating standards for malignant respiratory conditions in our guide to respiratory cancer VA ratings.

Asbestosis and Interstitial Lung Disease (Diagnostic Code 6833)

Asbestosis is evaluated under Diagnostic Code 6833, which governs interstitial lung diseases. Unlike malignancies, asbestosis does not automatically qualify for a 100 percent rating. VA applies the general rating formula for interstitial lung diseases based on Pulmonary Function Test (PFT) scores.

The rating formula evaluates two primary measurements: Forced Vital Capacity (FVC) and Diffusion Capacity of the Lung for Carbon Monoxide (DLCO). The specific percentage ratings break down as follows:

A veteran who is dependent on supplemental oxygen or develops pulmonary hypertension receives a 100 percent rating regardless of other pulmonary test numbers. You can calculate how these ratings combine with other service-connected conditions using our VA disability rating calculator.

Evidence Checklist for a Shipyard Asbestos Claim

To establish direct service connection for toxic exposure at Portsmouth Naval Shipyard, you must assemble three core elements of evidence. Omitting any of these three components results in claim denial.

Follow this numbered checklist when compiling your claim packet:

  1. Current formal medical diagnosis: You must submit medical records showing an active diagnosis of an asbestos-related disease, such as mesothelioma, asbestosis, or lung cancer. Imaging reports, biopsy results, and PFT records provide documented baseline clinical evidence.
  2. Proof of in-service shipyard exposure: You must provide military service records, official personnel files, transfer orders, or certified lay statements (buddy statements) placing you on Seavey Island or aboard submarines undergoing overhaul during periods when asbestos was in active use.
  3. Competent medical nexus opinion: You must include a written opinion from a qualified physician stating that your diagnosed condition is at least as likely as not related to your in-service asbestos exposure. Review our detailed nexus letter guide to understand how physicians format and support these medical assessments.

Once you submit these materials, VA schedules a C&P exam to verify pulmonary limitations and confirm the nexus opinion before assigning a final rating.

Comparison: PACT Act Presumptions vs Asbestos Direct Connection

Comparing statutory presumptive claims with shipyard asbestos claims highlights why direct service connection requires more preparation. Presumptions relieve the veteran of proving an in-service nexus, whereas asbestos claims demand evidence for every link in the chain.

The following table outlines the operational differences between these two claim types:

Claim Feature PACT Act Presumptive Pathway Shipyard Asbestos Direct Pathway
Legal Authority Public Law 117-168 (PACT Act 2022) 38 CFR § 3.303 and 38 CFR § 4.97
Medical Nexus Requirement Presumed by law for designated locations and illnesses Required; claimant must supply or establish via C&P exam
Exposure Verification Service records showing deployment to qualifying zones Specific evidence of shipyard assignment and asbestos handling
Adjudication Manual Standard M21-1 Part VIII presumptive toxic exposure provisions M21-1 Part VIII, Subpart iii, Chapter 7, Section B
Latency Consideration Covered under statutory presumptive timelines Claims processor must weigh decades of latency against civilian work history

If your service also included shipboard duty elsewhere, compare your assignments against our Blue Water Navy ship list or review our guide to Agent Orange domestic storage sites for separate exposure criteria.

Asbestos Bankruptcy Trusts and VA Disability Compensation

Veterans diagnosed with asbestos-related illnesses often discover that private manufacturers set up court-ordered trust funds following bankruptcy proceedings. These asbestos bankruptcy trust funds exist to compensate victims harmed by industrial insulation products used aboard Navy vessels.

Compensation received from an asbestos bankruptcy trust fund is completely separate from VA disability compensation. Filing a trust claim does not disqualify you from receiving tax-free monthly VA disability payments. VA does not offset, reduce, or recoup your monthly disability compensation based on funds recovered from a private asbestos trust.

You may pursue both avenues simultaneously. VA disability compensation provides monthly financial support and medical care through the Veterans Health Administration. Asbestos trusts provide financial recoveries from the manufacturers who supplied hazardous materials to military shipyards.

Who This Guidance Does Not Serve

This claims pathway does not serve civilian shipyard workers who never served on active military duty. Civilian employees injured at Portsmouth Naval Shipyard fall under the Federal Employees' Compensation Act or the Longshore and Harbor Workers' Compensation Act, administered by the United States Department of Labor rather than VA.

This guidance also does not serve veterans who lack an official medical diagnosis. Suspected toxic exposure without an identifiable, diagnosed illness cannot receive a VA disability rating. If you suspect exposure but currently show no symptoms, arrange a screening with a pulmonologist before filing a disability claim.

What Would Change This Claims Pathway

Our assessment of this claims pathway would change if Congress enacted legislation adding shipyard asbestos exposure to the statutory presumptive list. If lawmakers created a blanket presumption for submarine overhaul facilities, veterans would no longer need to secure private medical nexus letters or prove specific material handling.

Until such legislation passes, direct service connection remains the mandatory framework for all Portsmouth Naval Shipyard asbestos claims. Prepare your medical records and exposure statements under current M21-1 standards so your claim receives fair consideration.
