CALL TO ORDERThe NAVSTA Newport Restoration Advisory Board (RAB) gathered at the Officers’ Club for their bimonthly meeting on Wednesday, May 16, 2012. The meeting started at 6:35 p.m. See enclosure (1) for the meeting agenda and enclosure (2) for the attendance list.
David Dorocz, the Navy Co-Chair, opened the meeting and welcomed the group.
APPROVAL OF PREVIOUS MINUTES
Kathy Abbass stated that the electronic mail she received only included the May meeting agenda and not March meeting minutes. Dave Dorocz stated that he will resend the March 21, 2012 meeting minutes. The March 21 and May 16 minutes will both be approved at the next RAB meeting on July 18, after all members have had a chance to review them.
PRESENTATION: NEW RI REQUIREMENTS FOR ARSENIC
Deborah Moore made a presentation on the new Rhode Island regulations for arsenic in soil. The presentation is included in enclosure (3). Deborah Moore highlighted the similarities and differences between the 2004 regulations and the new 2011 regulations. The biggest change is that now there are three categories for arsenic contamination instead of two. The 2004 regulations had one set of remedial options for arsenic releases between 7 and 15 ppm and another set of remedial options for arsenic releases above 15 ppm. The 2011 regulation has three categories of arsenic contamination: 7-15 ppm, 15-43 ppm, and above 43 ppm. In both the 2004 and 2011 regulations, the criteria are the same for both residential and industrial land uses. These regulations apply when arsenic is the only contaminant in soil, so they will likely not apply to any of the IR sites.
The average surface soil arsenic concentration at Naval Station Newport is between 15 and 43 ppm. Naval Station Newport has a Soil Management Plan (SMP) signed by the Navy and RIDEM. The SMP is based on the old 2004 arsenic regulations. The Navy is currently working with RIDEM to update the SMP to the new 2011 regulations. Previously, under the old SMP, the Navy placed 2 feet of clean fill as surface soil for all construction projects. If the new SMP is approved, the Navy will only need to use 6 inches of clean fill for all construction projects, in accordance with the 2011 RIDEM regulations. This change would be a significant cost savings for the Navy.
Manuel Marques asked why different states have different regulations for arsenic. Kymberlee Keckler replied that different assumptions are used by different states to calculate the criteria for arsenic, but that the numbers are similar.
David Brown asked what happens if there are other contaminants in addition to arsenic. Deborah Moore replied that if arsenic is not the only contaminant, then other regulations are used.
David Brown asked if the new soil could be more contaminated than the soil that was removed. Deborah Moore replied that all clean fill is tested to ensure that it is below residential criteria for all contaminants.
PRESENTATION: DRAFT STUDIES PENDING AGREEMENT
Steve Parker explained the Document Review Status (enclosure 4). This table shows the current progress of each of the draft documents. This table is more detailed than the Site Summary Chart (enclosure 5) which just provides a general overview of site progress.
FIELD WORK UPDATE
Steve Parker stated that groundwater sampling for natural attenuation parameters is currently being conducted at NUSC. Field work at the ethyl blending plant at Tank Farm 1 will begin before the July RAB meeting.
TOPICS/PRESENTATIONS FOR UPCOMING MEETINGS
Ginny Lombardo suggested discussing Carr Point at the July RAB meeting.
The public meeting to present the Proposed Remedial Action Plan for the NUSC Site (Site 08) will be held immediately following the RAB meeting on July 18. This is part of the public comment period for that proposed remedy, and comments will be taken orally at that time from a stenographer.
To allow for ease of public participation in the public meeting portion, the July RAB meeting will be held at an off-site location, and that location will be announced later.
Thurston Gray reported that 5 of 16 members were present at the meeting. Two members were excused. There are no new members in the works.
David Brown distributed an article about an explosion at the Naval Underwater Ordnance Station in 1955 (enclosure 6). David Brown wondered if this explosion may have impacted any of the IR sites. Deborah Moore stated that Building 115, where the explosion occurred, is not located near any of the IR sites.
The next meeting of the RAB will be held on July 18, 2012 at 6:30 PM. The July RAB meeting will be held at an off-site location, and that location will be announced later. The public meeting for the NUSC proposed plan will be held immediately following the RAB meeting on July 18.
Meeting adjourned at 7:45 PM.
