Emergency Response

1.1.2 Site Description
 
The Samoa Pulp Mill Site is a 70 acre former industrial pulp manufacturing facility.  The pulp mill was constructed in 1963 by Georgia Pacific.  In the early 1970's Louisiana Pacific acquired and ran the facility until 1990.  From 1990 until 2008 various smaller groups owned and operated the facility.  The last operating owner of the facility was the Evergreen Pulp Company which ran the facility until 2008.  Evergreen experienced financial difficulties and "walked away" from the mill site without properly closing operations.  Sometime in 2009 a venture group called Freshwater Tissue Company purchased the facility site with intent of converting to a tissue mill.  This quickly failed to reach fruition and Freshwater began scrapping the facility and consolidating hazardous waste.  In August of 2013 Freshwater Tissue Company sold the facility to the Humboldt Bay Harbor, Recreation, and Conservation District (the “Harbor District”). The facility is currently staffed with 2 part-time Humboldt Bay Harbor District employees.

1.1.2.1 Location

The Samoa Pulp Mill Site is located within Humboldt County in Samoa, CA.  The Site is approximately 70 acres of industrial pulp processing operations and is situated on the North Spit of Humboldt Bay.  The facility is on the shore line of Humboldt Bay and has an industrial wharf on the Bay.  The Pacific Ocean is located within 800 yds to the west of the facility.

1.1.2.2 Description of Threat

The primary concern was 11 ASTs containing approximately 3 million gallons of highly caustic liquids (pH greater than 13).  Five of these ASTs were not designed to store caustic liquids and periodic seismic activity (6.8 earthquake occurred off coast of Humboldt Co. 3/9/2014) caused grave concern regarding their stability.  Additionally, there were a half dozen ASTs containing 2000-3000 gallons of sulfuric acid (pH less than 1), 3,000 tons of corrosive sludges in uncontained areas, approximately 3000 gallons of turpentine, and several thousand containers of various types (i.e., compressed gas cylinders, paints/thinners, mercury containing gauges and equipment).

2. Current Activities
  2.1 Operations Section
   

2.1.1 Narrative

The first five tanks of pulping liquor transferred for reuse were the tiled concrete tanks (Tile Tanks).  These tanks were never intended to store the black and green pulping liquors that were transferred into them by Freshwater Tissue Company.  The decision to start with these tanks was based on a 6.8 magnitude earthquake that occurred off the coast of Humboldt County on March 10, 2014 (see Polrep 7) and the fact that this earthquake had caused more cracks and resultant leaks.  Once the Tile Tanks were emptied our contractor began moving liquors from the remaining tanks that were constructed of steel.  The Tile Tanks were never cleaned of the pulp slurry residue. 

 

The tops of the Tile Tanks are made of fiberglass and are in various states of decay and disrepair.  This allowed rainwater in and over the course of the past two years, several feet of rainwater accumulated inside them.  The pH of the contaminated rainwater was approximately 11-12.  This rainwater was neutralized with citric acid and sprayed around the southwest corner of the site.

 

The pH of the pulp slurry that remains in the Tile Tanks is 7-9 and is non-hazardous waste.
