76 YEARS: Hunters Point & the Dawn of Nuclear Era
On July 16, 1945, the USS Indianapolis departed Hunters Point Naval Shipyard carrying components of a bomb code-named “Little Boy,” including half of the highly enriched uranium then in existence in the world. It was headed to Tinian Island in the Pacific. On August 6, the Enola Gay left Tinian and dropped the assembled atomic bomb on Hiroshima.

Sailors – and their clothing – contaminated by nuclear work at HPNS were washed at the site, with the contaminated rinse water going down the drains and leaking into the soil through breaks in the lines.
22
Naval Radiological Defense Laboratory
In addition to the decontamination of ships from the Pacific nuclear tests, the Naval Radiological Defense Laboratory was established at HPNS.
It participated in all Pacific nuclear tests from 1950-1958 as well as doing extensive research at HPNS with large quantities of radionuclides, including nuclear weapons debris brought back for analysis.
23
An array of animals were irradiated and injected with radioactivity at HPNS, potentially contaminating portions of the site by releases from excrement and incineration of carcases.

could contaminate more than 200 million metric tons of soil above EPAs default Superfund preliminary remediation goal
a millionth of an ounce if inhaled will cause cancer with a
virtual 100% statistical certainty
To put these large amounts into perspective
HPNS was declared a Superfund site in 1989
The subsequent botched cleanup has been riddled with scandal and failure of oversight
27
The present crisis regarding the botched HPNS cleanup
28
at 90-97% of HPNS survey units.
EPA did not publicly disclose this; PEER had to obtain the EPA findings under FOIA and make them public.

Tetra Tech Falsifications

97% of measurements were found to be suspect
31
EPA Found Only 3% of Samples to Be Free of Falsification
32
33
Unprecedented Falsification
“The vast scope of the signs of falsification found is unprecedented nationally.”
34
Tetra Tech Scandal is just
the Tip of the Iceberg
35
How did the Navy and EPA Fail to Catch Such Monumental Falsification for So Many Years?
These failures of oversight were not limited to the Tetra Tech matter, but extend to the whole cleanup.
II. EPA Repeatedly Approved Navy HPNS Cleanup Goals That Were Even at the Time Extremely Outdated, Non-protective & Inconsistent with EPA CERCLA Guidance,
and Thus Violated CERCLA 120(a)(2)
36
Under Section 120(a)(2) of CERCLA, the Navy Is Required to Use Standards
Consistent with EPA’s Superfund Guidance, But EPA Failed to Require it to Do So
37
“No department, agency, or instrumentality of the United States may adopt or utilize any such guidelines, rules, regulations, or criteria which are inconsistent with the guidelines, rules, regulations, and criteria established by the [EPA] Administrator under this chapter.”
EPA Has Historically Required Federal Agencies Comply with CERCLA 120(a)(2) and Employ Standards Consistent with EPA Guidance
38
Example:
“CERCLA section 120(a)(2) prohibits Federal Facilities from adopting or utilizing any rule, guidance or criteria applicable to CERCLA remedial actions that are inconsistent with EPA CERCLA remedial action requirements. This section makes clear that Federal Facilities are held to the same standards and requirements as non-federal facilities.”
December 12, 1997, letter from Woolford and Luftig, EPA OSWER (OLEM predecessor) to DOE’s Berube.
OLEM CERCLA Radiation Guidance Makes Clear That Cleanup Approaches from Other Agencies Should Not Be Used; Approaches That Do Not Follow OLEM Policies & Guidance Should Not Be Used
39
Q10. For CERCLA risk assessments at remedial sites, is it appropriate to use guidance or
approaches developed by other Federal, State or Tribal Agencies or by International
or National Organizations?
A. EPA has made the policy decision that risks from radionuclide exposures at remedial sites
should be estimated in the same manner as chemical contaminants, which is consistent
with EPA’s remedial program implementing guidance (e.g., EPA 1997g, 1999d, 2000f). Consequently, approaches that do not follow the remedial program’s policies and
guidance should not be used at CERCLA remedial sites. Should regional staff have
questions, they should consult with the Superfund remedial program’s National Radiation
Expert (Stuart Walker of OSRTI at the time this fact sheet was issued, at (703) 603-8748
or walker.stuart@epa.gov), before using guidance from other organizations that is not
already incorporated into this and other EPA Superfund remedial program guidance.
OSWER 9285.6-20 “Radiation Risk Assessment at CERCLA Sites: Q&A,” June 13, 2014
Q16. What calculation methods or multimedia radionuclide transport and exposure models are recommended by EPA for Superfund risk assessments?
A. The PRG calculators (U.S. EPA 2002a, 2007, 2009a), which are used to develop risk-based PRGs for radionuclides, are recommended by EPA for Superfund remedial radiation risk assessments.

Despite the Requirements that Cleanup Standards be Consistent with EPA’s CERCLA Guidance, the Navy is Using Standards that are Inconsistent with that Guidance.

42
The Navy’s Hunters Point Release Criteria
43
The HPNS remedial goals were put forward in an Action Memorandum and then repeatedly used in Records of Decision (RODs) that were approved by EPA. The soil goals, however, came from EPA 1991 PRGs and the building standards from a 1974 AEC guidance (Reg. Guide 1.86) and 25 mrem/yr based on RESRAD. None of these were consistent with EPA guidance. As the Navy stated:
Soil Cleanup Goals Are Extremely Outdated
44
Radionuclide | Navy Remediation Goals for Soil (pCi/g) | 2021 EPA Default PRG for soil (pCi/g) | How many times weaker are the Navy’s Remediation goals? |
Radium-226 | 1.861 | 0.00192 | 969 times weaker |

Thorium-232 | 1.690 | 0.0017 | 994 times weaker |
Uranium-235 | 0.195 | 0.00708 | 28 times weaker |
45
The cancer risk from the Navy Soil Cleanup Standards is, according to the EPA’s PRG Calculator, 2.12 x 10-3, meaning
1 in every 473 people would get a cancer from the radioactive contamination.
This is 2,120 times higher than EPA’s risk goal and 21 times higher than the upper end of the risk range.

The Navy’s Soil Cleanup Standards Would Allow 332 millirem per year, the Equivalent of ~166 Chest X-rays Annually, Year After Year
The Navy soil standards, approved by EPA, would allow the public to receive essentially a chest X-ray every other day for decades, with no medical benefit, and no informed consent.
[Note that OLEM guidance declares any ARAR (Applicable or Relevant and Appropriate Requirements) over 12 millirem/year presumptively non-protective.]

The Navy’s release criteria were supposedly based on 10-6 risk
But the criteria the Navy used--soil PRGs from 1991 and the Atomic Energy Commission’s 1974 Reg. Guide 1.86 values for buildings--were wrong and inconsistent with EPA CERCLA guidance, in violation of CERCLA 120(a)(2) and greatly exceed 10-6, indeed exceed the upper limit of the risk range.
The errors need to be corrected and current 10 -6 PRGs used
10-6 is the CERCLA Point of Departure
“The 10-6 risk level shall be used as the point of departure for determining remediation goals for alternatives when ARARs are not available or are not sufficiently protective because of the presence of multiple contaminants at a site or multiple pathways of exposure” 40 CFR 300.430(e)(2)(i)(A)(2)
51
To Fall Back From 10-6 Requires Consideration of the 9 Balancing & Other CERCLA Criteria--
Which Has Never Been Done at HPNS
“Nine criteria for evaluation. The analysis of alternatives under review shall reflect the scope and complexity of site problems and alternatives being evaluated and consider the relative significance of the factors within each criteria.”
40 CFR 300.430(e)(9)(iii)
52
The Nine CERCLA Threshold, Balancing, & Modifying Criteria
53
1. Overall protection of human health and the environment
2. Compliance with ARARs (applicable or relevant and appropriate standards)
3. Long-term effectiveness and permanence
4. Reduction of toxicity, mobility or volume
5. Short-term effectiveness
6. Implementability
7. Cost
8. State acceptance
9. Community acceptance
Current Time Urgent Matter
Despite CERCLA 120(a)(2) requiring the use of cleanup guidance consistent with EPA’s, the Navy is refusing to use EPA’s Building PRG Calculator for setting cleanup standards for contaminated buildings at HPNS. We have reason to believe--in part because of EPA strenuous resistance to providing in a timely fashion documents under FOIA related to the Navy-EPA disagreement--that the Region may be intending to cave in to Navy demands on the matter, and to do so without informing and getting approval from OLEM top leadership.
54
Adverse National Impacts Were This to Happen
This could not only place people in the Hunters Point area at risk but could impact cleanup of large numbers of other contaminated sites across the country, where Responsible Parties have been pushing to use less protective standards not consistent with EPA’s guidance. This pending action could undermine EPA authority nationally.

The Navy’s Building Remedial Goals for External Contamination Are Vastly Less Protective than Those Specified by EPA Guidance
58
The Navy cleanup levels for external contamination would produce cancer risks, according to EPA’s BPRG calculator, of
~1 x 10⁻2 -- ~1 in every 100 people exposed would get a cancer from the contamination.
That is about 10,000 times higher than the EPA risk goal and about 100 times higher than the upper limit of the risk range.

61
The Navy cleanup levels for settled dust would produce cancer risks, according to EPA’s BPRG calculator, of 1.6 x 10⁻² -- 1 in every 62 people exposed would get a cancer from the contamination.
That is 16,000 times higher than the EPA risk goal and 160 times higher than the upper limit of the risk range.

64
The Nonprotective HPNS Cleanup Standards Also Have Contributed to Radioactive Waste Being Shipped to Disposal Sites Not Licensed for LLRW
This is part of a larger national issue involving troubling efforts within EPA to allow radioactive waste to be disposed of in Subtitle C, and perhaps even Subtitle D, landfills.
65
EPA Refusal to Admit & Fix the Cleanup Standards Errors
Rather than admit it made an error in approving the Navy’s woefully non-protective cleanup standards for soil and buildings, and committing to fixing them, EPA is instead misusing the 5-Year Review process to allow contamination levels 100 times higher.
66
III. Navy & EPA Quietly Shifted Remedy from Cleanup to Coverup
67
Navy shifts from remediating to covering up contamination
68
The 1997 Record of Decision (ROD) for Parcel B called for excavation and off-site disposal of contaminated soil. (1997 Parcel B ROD, p. 49, 65)
Work at Parcel B found far more contamination than the Navy had anticipated. (Amended Parcel B ROD, p. 1-5)
In the 2009 Amended ROD for Parcel B, the Navy changed its remedy to rely on covering rather than removing contamination:
“...the consideration of parcel-wide covers to address soil contamination instead of excavation represents a fundamental change in the scope of the remedy for soil.” (Amended Parcel B ROD, p. 1-4)
Remedy now relies primarily on “durable covers,” which are defined in the RODs as 2 feet (or in some cases 3) of “clean soil”
or 4 inches of asphalt.
69
Among the Key 9 Criteria are Community Acceptance
“Community acceptance. This assessment includes determining which components of the alternatives interested persons in the community support, have reservations about, or oppose. This assessment may not be completed until comments on the proposed plan are received.”
40 CFR 300.430(e)(9)(iii)(I)
70
Violation of Community Acceptance�(one of the 9 CERCLA Criteria)
71
Rather than clean up HPNS to the most protective standards to allow for unrestricted use, much of the contamination will now be left in place and unenforceable restrictions will be placed on the future uses of the site, contrary to official San Francisco policy.
Proposition P: Public Overwhelmingly Supports Highest Cleanup Standards, Unrestricted Use
Passed in 2000 with 86.4% in favor
“While the federal government is required by law to clean up the Shipyard, the Navy says it will cost too much to do a thorough job. Instead, the Navy plans to leave behind so much contamination that it will increase the risk for cancer resulting from exposure to the property, requiring the construction of barriers and the restriction of future land uses.”
“Hunters Point Shipyard [must] be cleaned to a level which would enable the unrestricted use of the property - the highest standard for cleanup established by the United States Environmental Protection Agency.”
72
SF Board of Supervisors Adopts Prop P as Official City and County Policy
“WHEREAS, Although the federal government is required by law to clean up the Shipyard, the Navy says it will cost too much money to do a thorough job. Instead, the Navy plans to leave behind so much contamination that the property may expose occupants and visitors to an unacceptable risk of cancer unless the Navy imposes legal restrictions on land use and constructs physical barriers; and
…
WHEREAS, The United States government should be held to the highest standards of accountability for its actions; and
73
74
WHEREAS, The United States Navy has demonstrated that it is not committed to responsible site management or cleanup and many in the Bayview Hunters Point community believe the department's disdain for its duties in this neighborhood stems from the racial make-up of its residents; and
WHEREAS The Hunters Point Bayview community wishes the Hunters Point Shipyard to be cleaned to a level which would enable the unrestricted use of the property - the highest standard for cleanup established by the United States Environmental Protection Agency; and
75
RESOLVED, That the Board hereby declares that Proposition P ... shall be the official policy of the City regarding the remediation of the Shipyard and sets forth a standard of remediation acceptable to the community;

EPA Tries to Get Around This by Claiming That All Gardens Will Be Raised Beds With Impermeable Bottoms
Completely unenforceable; nothing can grow under such circumstances; a regulatory fiction designed to allow vastly higher concentrations of contaminants than permitted for unrestricted residential use.

With the Garden Pathway Included, the Risk Associated with the Navy Remediation Goals is Far, Far Outside the Acceptable Risk Range
When the garden pathway is included, as it should be, the PRG-based risk is 2 x 10-3, far, far above the upper end of acceptable risk levels.
When chemicals are included, as they must be, the risk is even further into the the 10-3 range, vastly exceeding acceptable risk.

EPA’s National Chemical Regional Screening Levels Need to Include the Garden Pathway, as the Radionuclide PRGs Do
For years there has been internal recognition at EPA that it needs to include the garden pathway in its Regional Screening Levels (RSLs) for chemicals, paralleling what the Radionuclide PRGs have long done. Direction should be given to initiate a scientifically thorough process of doing so. This is particularly important because communities of color disproportionately rely on homegrown fruits and vegetables.
[Adding the homegrown produce pathway for toxic chemicals will require, as the Rad PRGs have done, use of extensive actual measured values for root uptake of the various contaminants into different types of edible plants (Bv-wet values), and not instead resorting to a simple, non-empirical formula based on Kow, that has been shown to be highly inaccurate.]

Coverup, not Cleanup of Contamination
98
Original cleanup promise: removal of contaminated soil
Contamination was found to be ubiquitous and cleanup costs higher than anticipated, so Navy modified cleanup plan to rely on covering contamination with 2 feet of “clean” soil or 4 inches of asphalt
Now, majority of contamination will be left in place on site, beneath a thin soil or asphalt cover
Development of the site will require tearing up the thin soil or asphalt covers and the contaminated soil beneath in order to build residences, shops, utility infrastructure, etc.

101
The years or decades of intense construction, involving tearing up the soil and asphalt covers and existing building foundations and digging deep into the contaminated soil beneath will produce potential for widespread dispersal of contamination and exposures to people.

ASK #1: Fix the Soil Cleanup Standards
Direct that the soil cleanup standards for Hunters Point be corrected so they are set at 10⁻⁶ for unrestricted residential use, based on the EPA PRG calculator using the EPA defaults and consistent with Prop P.
Commence a scientifically rigorous process to include the garden pathway in EPA’s national Regional Screening Levels for toxic chemicals, parallel to how it has been done in its radionuclide PRGs.
