2.1.1 Narrative/On Site Activities
Over the last Beginning in early March, project activities included multiple site walks with ERRS and/or START contractors to discuss issues
including site layout and preparatory activities, site resource needs and
logistics, subcontracting issues, and administrative site functions. Site walks occurred with both contractors on
March 14th and 31st while EPA met with on site with ERRS contractors
only on April 7th. During the
March 31st site walk, adjoining property owners met with EPA and
contractors to discuss site objectives and lease agreements to the proposed
site activities.
Mobilization to the site for the initiation of preparatory
construction activities occurred on April 11.
The site currently is divided into three work zones: the landfill area defined as the exclusion zone, bounded by the northeastern adjoining property, Airport Auto Wrecking, state highway 3 on the northwest, and adjoining private undeveloped properties on the south east side. Some of the adjoining prosperities on the southeast,and south west of the landfill boundary has been leased for use as the command post, stockpile area, and haul routes. Additionally access through other adjoining properties to the northeast of the landfill has also been acquired.
April 11 - EPA and contractors mobilized initial site
resources including temporary staging of the EPA Mobile Command Post (MCP). Primary site activities consisted of a safety
call including EPA/START/ERRS contractors and a site walk including all
contractors. Initial ERRS heavy
machinery rentals were delivered to site.
April 12 - ERRS begins construction of the primary haul road
planned for moving staged landfill waste off-site. The haul road, approximately one mile in
length, starts at the eastern extent of the Bremerton National Airport and
continues northeast towards the staging area.
Haul road construction included clearing and grubbing of the roadway and
road rolling of on-site fill material used for the base of the roadway. Fill material primarily originated from the
stockpile (laydown) area adjoining the landfill to the southwest.
A site walk with the landowner leasing access
to the site in the area of the haul road occurred. Issues associated with haul road
construction, areas acceptable for borrow and areas of concern to the landowner
in the area of the landfill.
April 13 – ERRS continues construction along haul road and
begins clearing and grubbing on landfill cap.
Electrical contractor on site for installation of utility poles. An additional pole was also installed on the berm near the southwest tip of the landfill, this pole is intended
for placement of a time lapse camera for documentation of the landfill excavation activities.
April 14 - Construction of the stockpile area is
initiated. Activities included
clearing and grubbing of the area and excavation and grading of stockpile cells
used to segregate the primary waste streams from the landfill. The stockpile cells will also allow for sampling results to be received prior to off site transportation. START contractor video recorded conditions of the property at the Airport Auto Wrecking adjoining the site to the northeast due to the need to access the property for activities associated with upstream creek diversion. START also recorded the roadway leading to the job trailer portion of the site off Hwy 3 SW through the Alpine Evergreen business park and along the fenceline of residential properties located along the haul road to the site.
April 15 – START Principal Engineer arrives on-site and
performs site walk with EPA, ERRS, and START to discuss sediment control and
stormwater protection activities. An approximate 800-gallon double-walled diesel tank is delivered to site. Installation of silt fence along sensitive areas of Haul road also occurred.
April 16 - Excavation continues for stock pile area and cells.
April 18 - ERRS Transportation & Disposal (T&D) Coordinator mobilizes to site to coordinate site walk and bid meeting with Disposal subcontractors. Representatives from five (5) disposal companies attended the meeting and surveyed the site conditions to prepare bids for the T&D Request For Proposal (RFP). ERRS activities include on-going site prep activities for stockpile area. The double-walled diesel tank was re-staged along haul road at entrance to stockpile area with upgraded secondary containment.
April 19 - Haul Road activities continued by laying down large aggregate material for road base.
Kitsap Count Public Health personnel visited the site escorting a reporter for the digital edition of the Kitsap Sun. OSC Rodin granted a videotaped interview to the reporter for the piece. Additionally initial discussion with Kitsap Health District in regards to notifying residents downstream of the site, due to the potential for future creek flows to change as a result of the landfill which has restricted creek flow for multiple decades.
Job trailers arrived and were staged at the command post area southwest of the stockpile area. START demobilized the MCP.
April 20 - ERRS installed sediment controls including stormwater catch ponds and
vegetation along the northwestern boundary of the stockpile area
anticipating potential discharges from this area.
START performed background soil sampling in the areas that could be impacted as a result of pending landfill excavation activities. A total of 8 composite samples were collected from the stockpile area, haul road easement, and the command post area. The samples were submitted for subcontract laboratory analyses for a range of analytes including VOCs/SVOCs/Metals/Herbicides/Pesticides/Dx/Gx/Asbestos.
April 21 - Sand for containment cell construction begins arriving on-site and stockpiled as haul road is extended to the stockpile area. An access road was cleared along the northeastern site boundary adjoining Airport Auto Wrecking facility leading to upstream end of Gorst Creek; this roadway will be used to access and maintain a pumping system for future creek flow diversion stream diversion.
ERRS further developed the haul road leading from the landfill to the stockpile area. Additionally, access to the upstream portion of the creek was provided by excavating a two-step bench with sediment controls installed to provide access for future pumps, which will be used for creek flow diversion.
Washington State Labor and Industries (WA LNI) contacted OSC Rodin with concerns regarding asbestos wastes which may be removed from the site.
April 22 - ERRS begins laying out sand used to construct the containment cells in the stockpile area. Surface debris was being segregated and stockpiled as clearing activities continued.
April 23 – Construction activities from previous day continued. Due to
difficulties in acquiring sand from an off-site source to construct the cells,
a source of native soil was secured on site. ERRS continued to clear the
landfill surface.
To date, approximately 1,200 tons of 2"-4" aggregate material has been delivered to site and laid down as road base for the haul road leading. Approximately 300 tons of < 5/8" aggregate material has been delivered for the service route along the northeastern boundary of the site to service pumps and provide access to the upstream portion of Gorst Creek; 660 tons of sand has been delivered for liner protection and protection of native soils from wastes staged in the stockpile area.
