10 | Shell Bank fire training area. | This site was used from 1943 to 1952 and from 1968 to 1980 for fire training. Fires
were deliberately set by igniting POL waste after it was poured onto old aircraft. This
site may also have received POL waste directly from a tank. Prior to 1971, a protein
foam was used to put out the fires during the training. Since 1971, aqueous film-forming
foams have been used to douse the fire. These foams consisted of fluorocarbon
surfactants with a petroleum base.
16B: two 20,000-gallon USTs removed in 1952. 16C: two 20,000-gallon tanks (aboveground?) was moved here from site 17A in 1968 and used till 1980. 16B and C stored diesel fuel, MOGAS, and leaded AVGAS. |

used fuels stored in two 20,000-USTs. Containers of fuel were also emptied into the
bermed area. Empty drums were seen near this site in 1968.
17B: This site is located east of 17A and was used to store PCB transformers removed from service. The transformers were stored in unlined areas on pallets. 17C. See site number 27. |
| 18/ OT-18 |
2 | Lynn Haven Defense Fuels Supply Point | This site was used from 1943 to an unknown date for the storage and dispensing of bulk
fuels. This site is no longer used. Bunker C fuel may have been dumped outside of the
west gate in early 1950s. This site was also used to steam clean drums and the wash
water was dumped on the ground behind the drum loading station.1
Six oil/water separators were used to treat stormwater and the effluent drained into North Bay. | |
| 18 | 2 | Sludge disposal areas | Since the 1950s, AVGAS, JP-4, and JP-5 have been stored at a tank farm at this location. Prior to 1969, tank sludges were buried within the diked areas. Sludges may have been removed during regrading and resurfacing.2 | |
| 18/ OT-18 |
2 | Underdrain field | Minor spills have occurred at the truck loading and railcar loading areas. An underdrain field was installed in 1980 beneath the railcar area. This field discharges to a series of oil/water separators. Bunker C fuel has been collected in the separators.2 | |
| A/ 19 |
18 | 4 | AAFES Service Station Former UST Area | Fuel tanks were installed in 1948 and found to be leaking in 1983. These tanks were replaced in 1988.5 This site is also known as Bldg 968 leaking underground storage tank. |

PUBLIC HEALTH ASSESSMENT CONCLUSION CATEGORIES
CATEGORY A : URGENT PUBLIC HEALTH HAZARD
This category is used for sites where short-term exposures (< 1 yr) to hazardous substances or conditions could result in adverse health effects that require rapid intervention.
This determination represents a professional judgement based on critical data which ATSDR has judged sufficient to support a decision. This does not necessarily imply that the available data are complete; in some cases additional data may be required to confirm or further support the decision made.
Criteria:
Evaluation of available relevant information* indicates that site-specific conditions or likely exposures have had, are having, or are likely to have in the future, an adverse impact on human health that requires immediate action or intervention. Such site-specific conditions or exposures may include the presence of serious physical or safety hazards, such as open mine shafts, poorly stored or maintained flammable/explosive substances, or medical devices which, upon rupture, could release radioactive materials.
* Such as environmental and demographic data; health outcome data; exposure data; community health concerns information; toxicologic, medical, and epidemiologic data.
ATSDR Actions:
ATSDR will expeditiously issue a health advisory that includes recommendations to mitigate the health risks posed
by the site. The recommendations issued in the health advisory and/or health assessment should be consistent with
the degree of hazard and temporal concerns posed by exposures to hazardous substances at the site.
Based on the degree of hazard posed by the site and the presence of sufficiently defined current, past, or future completed exposure pathways, one or more of the following public health actions can be recommended:
This category is used for sites that pose a public health hazard due to the existence of long-term exposures (> 1 yr) to hazardous substance or conditions that could result in adverse health effects.
This determination represents a professional judgement based on critical data which ATSDR has judged sufficient to support a decision. This does not necessarily imply that the available data are complete; in some cases additional data may be required to confirm or further support the decision made.
Criteria:
Evaluation of available relevant information* suggests that, under site-specific conditions of exposure, long-term exposures to site-specific contaminants (including radionuclides) have had, are having, or are likely to have in the future, an adverse impact on human health that requires one or more public health interventions. Such site-specific exposures may include the presence of serious physical hazards, such as open mine shafts, poorly stored or maintained flammable/ explosive substances, or medical devices which, upon rupture, could release radioactive materials.
*Such as environmental and demographic data; health outcome data; exposure data; community health concerns information; toxicologic, medical, and epidemiologic data.
ATSDR Actions:
ATSDR will make recommendations in the health assessment to mitigate the health risks posed by the site. The
recommendations issued in the health assessment should be consistent with the degree of hazard and temporal
concerns posed by exposures to hazardous substances at the site. Actions on the recommendations may have
occurred before the actual completion of the public health assessment.
Based on the degree of hazard posed by the site and the presence of sufficiently defined current, past, or future completed exposure pathways, one or more of the following public health actions can be recommended:
This category is used for sites when a professional judgement on the level of a health hazard cannot be made because information critical to such a decision is lacking.
Criteria:
This category is used for sites in which "critical" data are insufficient with regard to extent of exposure and/or toxicologic properties at estimated exposure levels. The health assessor must determine, using professional judgement, the "criticality" of such data and the likelihood that the data can be obtained and will be obtained in a timely manner. Where some data are available, even limited data, the health assessor is encouraged to the extent possible to select other hazard categories and to support their decision with clear narrative that explains the limits of the data and the rationale for the decision.
ATSDR Actions:
ATSDR will make recommendations in the health assessment to identify the
data or information needed to adequately assess the public health risks posed
by the site.
Public health actions recommended in this category will depend on the hazard potential of the site, specifically as it relates to the potential for human exposure of public health concern. Actions on the recommendations may have occurred before the actual completion of the public health assessment.
If the potential for exposure is high, initial health actions aimed at determining the population with the greatest risk of exposure can be recommended. Such health actions include:
If the population of concern can be determined through these or other actions, any of the remaining follow-up health activities listed under categories A and B may be recommended.
In addition, if data become available suggesting that human
exposure to hazardous substances at levels of public health concern is occurring
or has occurred in the past, ATSDR will reevaluate the need for any followup.
This category is used for sites where human exposure to contaminated media may be occurring, may have occurred in the past, and/or may occur in the future, but the exposure is not expected to cause any adverse health effects.
This determination represents a professional judgement based on critical data which ATSDR considers sufficient to support a decision. This does not necessarily imply that the available data are complete, in some cases additional data may be required to confirm or further support the decision made.
Criteria:
Evaluation of available relevant information* indicates that, under site-specific conditions of exposure, exposures to site-specific contaminants in the past, present, or future are not likely to result in any adverse impact on human health.
*Such as environmental and demographic data; health outcome data; exposure data; community health concerns information; toxicologic, medical, and epidemiologic data; monitoring and management plans.
ATSDR Actions:
If appropriate, ATSDR will make recommendations for monitoring or other
removal and/or remedial actions needed to ensure that humans are not exposed to
significant concentrations of hazardous substances in the future.
Actions on the recommendations may have occurred before the actual completion
of the public health assessment.
The following health actions, which may be recommended in this category, are based on information indicating that no human exposure is occurring or has occurred in the past to hazardous substances at levels of public health concern. One or more of the following health actions are recommended for sites in this category:
However, if data become available suggesting that human exposure
to hazardous substances at levels of public health concern is occurring, or
has occurred in the past, ATSDR will reevaluate the need for any followup.
This category is used for sites that, because of the absence of exposure, do NOT pose a public health hazard.
Criteria:
Sufficient evidence indicates that no human exposures to contaminated media have occurred, none are now occurring, and none are likely to occur in the future.
ATSDR Actions:
No public health actions are recommended at this time because no human
exposure is occurring, has occurred in the past, or is likely to occur in the
future that may be of public health concern.
