Soil Management Plan

Naval Station Newport, Newport, RI

This Soil Management Plan (SMP) has been prepared to establish procedures that will be followed should future construction, demolition or maintenance activities at the Naval Station Newport (NAYSTA) require the need to manage disturbed or excavated soil. The plan cannot be used to manage soils on Navy Installation Restoration (IR) sites, soils with known contamination, such as PCBs, asbestos, or mercury, soils regulated by the State of RI with contamination other than arsenic, and on propelty leased to private entities (e.g .

pri vatized Housing) .

Background

The property, located in Newport, RI, was established in 1869 with the construction of a torpedo station. The Navy War College was added in 1884 and the site was used for sailor training and housing and fueling facilities during World War II. Post WWII the property footprint and training activities were reduced while research and development efforts were increased . The soils on the property were found to contain arsenic that exceeds regulatory levels during a property-wide site investigation that included the collection and analysis of more than 1000 soil samples These soils must be removed and disposed of, or covered with Department (i.e. State of Rhode Island Department of Environmental Management) approved engineered controls, consisting of building foundations, asphalt pavement, and landscaping and environmental land use controls (ELUR) in order to prevent direct exposure to regulated soils.

Applicable Area

This SMP, and affiliated ELUR (when applicable), restricts the property to industrial or commercial usage, and pertains to the entire property. See attached site figure.

Soil Management

The direct exposure pathway is the primary concern at the site. Individuals engaged in activities at the site may be exposed through incidental ingestion, dermal contact, or inhalation of entrained soil particles if proper precautions are not taken. Therefore, the following procedures will be followed to minimize the potential of exposure.

During site work, the appropriate precautions will be taken to restrict unauthorized access to the property.

During all site/earth work, dust suppression (i.e. watering) techniques must be employed at all times. In the event that an unexpected observation or situation arises during site work, such activities will immediately stop (such as olfactory or visual evidence of waste material or contamination, PCB contamination or asbestos debris disposal). Workers will not attempt to handle the situation themselves but will contact the appropriate authority for fUlther direction.

If excess soil is generated /excavated from the property, the soil is to remain on-site for analytical testing, to be performed by an environmental professional, in order to determine the appropriate disposal and/or management options. The soil must be placed on and covered with polyethylene/plastic sheeting during the entire duration of its staging and secured with appropriate controls to limit the loss of the cover and protect against storm-water and/or wind erosion (i .e. hay bales, silt fencing, rocks, etc).

Excavated soils will be staged and temporarily stored in a designated area of the property.

Within reason, the storage location will be selected to limit the unauthorized access to the materials (i.e. away from public roadways/walkways). No soil will be stockpiled on-site for greater than 60 days without prior Department approval.

Soils excavated from the site may not be re-used as fill on residential property.

Excavated fill material shall not be re-used as fill on commercial or industrial properties unless it meets the Department's Method 1 Residential Direct Exposure Criteria for all constituents listed in Table 1 of the Rules and Regulations for the Investigation and Remediation of Hazardous Material Releases (Remediation Regulations) .

Excavated soil to be reused on non-Navy commercial or industrial properties must be sampled and analyzed, by a qualified environmental professional, at a frequency of one sample per 500 tons for all constituents in Table 1. Copies of the laboratory analysis results shall be maintained by the site owner and included in the annual inspection report for the site, or the closure report if applicable. In the event that the soil does not meet any of these criteria, the material must be properly managed and disposed of off site at a licensed facility.

Site soils, which are to be disposed of off-site (and not reused off-site), must be done so at a licensed facility in accordance with all local, state, and federal laws. Copies of the material shipping records associated with the disposal of the material shall be maintained by the site owner and included in the annual inspection report for the site.

Best soil management practices should be employed at all times and regulated soils should be segregated into separate piles (or cells or containers) as appropriate based upon the results of analytical testing, when mUltiple reuse options are planned (i.e. reuse on site, reuse at a Department approved industrial/commercial property, or disposal at a Department approved licensed facility) .

All non-disposable equipment used during the soil disturbance activities will be properly decontaminated as appropriate prior to removal from the site. All disposable equipment used during the soil disturbance activities will be properly containerized and disposed of following completion of the work. All vehicles utilized during the work shall be properly decontaminated as appropriate prior to leaving the site.

At the completion of site work, all exposed soils that remain on the site (i.e. have not been removed to licensed disposal facility) are required to be recapped with Department approved engineered controls (i.e. 2 feet of clean fill or equivalent; building foundations;

4 inches of pavement/concrete underlain with 6 inches of clean fill; and/or 1 foot of clean fill underlain with a geotextile liner) consistent or better than the site surface conditions prior to the work that took place. These measures must also be consistent with the Department approved ELUR recorded on the property. Any clean fill material brought on site is required to meet the Department's Method I Residential Direct Exposure Criteria or be designated by an Environmental Professional as Non-Jurisdictional under the Remediation Regulations. The Annual Inspection Report for the site, or Closure Report if applicable, should include either analytical sampling results from the fill demonstrating compliance or alternatively include written certification by an Environmental Professional that the fill is not jurisdictional.

Worker Health and Safety

To ensure the health and safety of on-site workers, persons involved in the excavation and handling of the material on site are required to wear a minimum of Level D personal protection equipment, including gloves, work boots and eye protection. Workers are also required to wash their hands with soap and water prior to eating, drinking, smoking, or leaving the site.

Department Approval

In accordance with the Departments ' requirements, no soil at the property is to be disturbed after an engineering control has been implemented in any manner without prior written permission of the Department's Office of Waste Management, except for minor inspections, maintenance, and landscaping activities that do not disturb the contaminated soil that is left in place.

As patt of the notification process, the Navy shall publish a notice, annually in the Newport Daily News that indicates that soil contain arsenic above the Department's Method 1 Direct Exposure Criteria, that soil work is planned on the property, and that individuals will be notified if work is to be done adjacent to privately-owned property.

In addition, the Navy will prepare an annual report to be submitted to the Department that summarizes construction work done on the property were soil was removed and inspections of sites on the property were soils with arsenic have been left in place and land use restrictions have been applied.

For soil that is removed, the report will identify the location, quantity, and ultimate destination. For sites with land use restrictions the inspections will include the location of the site and certification that the engineering controls remain in place.
