Subject: Statement of Qualifications to Assist in 2017 US EPA Community-Wide Brownfields Assessment Grant Award, City of Arcata, California
Dear Ms. Marsolan and Selection Committee Members:
Congratulations on receiving the US EPA Brownfields assessment grant! We recognize that funding is limited, and our approach is to stretch the grant award as far as possible for the purposes of encouraging infill development, minimizing human exposure, and limiting environmental effects.
As detailed in the attached SOQ, the City can trust that our team will provide the best value because:
• We have assisted in seven US EPA Brownfields sites within Humboldt County over the last ten years, and we know regulatory procedures and technical realities. At one of these sites, Tuluwat Village on Indian Island, we brought the project from Phase I site investigation to Phase III remediation and reuse. The Wiyot Tribe won two awards for this achievement, a US EPA Region 9 Excellence in Site Reuse Award (awarded in August 2017) and an American Council of Engineering Companies Engineering Excellence Award (2013).
• We have experience and background knowledge of the Little Lakes industrial site. SHN provided critical review of the Phase II investigations, assisted the city with stockpile characterization, performed the Kiln characterization, and assisted with the demolition and disposal of the Kiln materials. Key staff from those projects will bring their knowledge forward, should we be selected; they are Mike Foget, PE; Marty Lay, PE; Roland Rueber, PG; and Erik Nielsen, PG and CHG.
• We have a track record of site closures. Regulatory agencies trust our work, and we know how to chart a path toward closure. For example, for 35 CALFIRE sites, we have 31 of them closed (89%). Maps and tables of closed sites are provided in our SOQ.
• We create innovative and energy efficient remediation solutions. We have used numerous types of real- time data collection systems, and in one case, using an advanced analytical technique saved $2 million in further remedial action. Energy efficiency is realized by designing passive techniques, such as in-situ chemical oxidation, oxygen diffusion, or passive sub-slab ventilation.
• We are local. Our team is comprised of SHN, the Redwood Community Action Agency (RCAA), North Coast Laboratories, and Fisch Drilling. Selecting a local team will save money on mobilization and travel, allowing more to be spent on cleanup.

iv Executive Summary
Executive Summary
After checking our company’s projects database, we found that the City of Arcata was one of SHN’s early clients; in 1983, K. Jeff Nelson (the “N” in SHN) evaluated the water distribution system in the Sunny Brae and Baywood neighborhoods. Since then, we have worked with the City on many projects, providing civil engineering, environmental, geologic and geotechnical engineering, planning, and materials testing services. The City is a key client for us, and if selected, we will continue providing service to the best of our abilities.
The purpose of this Executive Summary is to 1) provide evidence that the SHN team is the best suited for a careful expenditure of the Brownfields grant funding, and 2) provide an overview of our approach to the Little Lake Industries investigation and remediation. Based on our experience and background knowledge of this site, we outline what we think is a reasonable approach, but we caution that regulatory agency staff will need to approve the results of investigations and remediation recommendations. The extent to which any consultant can provide a plan for the Little Lake Industries site will largely depend on how well they can communicate with agency staff, and the degree of trust already established with them. For evidence of the good will between SHN and agency staff, we present that SHN has closed over 100 contaminated site investigations and clean ups in our 30+ years of providing environmental services.
Overview of Approach to Little Lakes Site For our approach to the Little Lakes site, we are proposing a different kind of strategy. Available data is more than 10 years old, and the regulators SHN was working with on the site at the North Coast RWQCB have since retired. In addition, the City has redevelopment plans in place, and historical data available; therefore, it would be prudent to discuss with the oversight agency before proposing an additional course of action, to save time and valuable funds.
Our plan is to succinctly summarize the available data for the site in a technical memorandum with our recommendations for additional investigation based on the proposed re-use plans for the site. Prior work has not included the additional reuse scenarios for the site. This information would be submitted to the RWQCB, and a meeting would be requested to discuss a path forward. The technical memorandum would include our recommendations for additional sampling to fill data gaps, in light of the proposed development plans. Additional sampling is warranted based on the existing data set, but we would like to tailor the investigation to the RWQCB concerns. We feel that it is important to acquire regulatory “buy-in” on sites with existing data and a proposed redevelopment plan, rather than proceed with the more cut-and-dry EPA Phase I/II protocol approach for sites with no data. Following the meeting with the RWQCB, we would then prepare the EPA required SAP/QAPP and HASP for additional sampling. We would then implement the hazardous materials phase II investigation. Depending on remaining concentrations of contaminants of concern at the Little Lakes site, elements of the redevelopment plan can be incorporated into the final selected remedy. Any remedial action selected at this site will be appropriate for beneficial reuse.
1 Executive Summary
Evidence of the SHN Team’s Qualifications The team we have assembled is comprised of SHN, the Redwood Community Action Agency (RCAA), North Coast Laboratories (NCL), and Fisch Drilling. All are located within Humboldt County (NCL and SHN have offices in Arcata, and all fulfill the requirements of California Small Business Enterprises. Our proximity will translate into more funds spent on investigation, and less on consultant travel and mobilization. The SOQ provides detailed information, but the following points summarize and support our team’s qualifications:
We have assisted in seven US EPA Brownfields sites within Humboldt County over the last ten years, and we know regulatory procedures and technical realities. At one of these sites, Tuluwat Village on Indian Island, we brought the project from Phase II site investigation to Phase III remediation and reuse. The Wiyot Tribe won two awards for this achievement, a US EPA Region 9 Excellence in Site Reuse Award (awarded in August 2017) and an American Council of Engineering Companies Engineering Excellence Award (2013). SHN has successfully performed over 1,000 site investigations, designed and supervised installation, and operated various remedial systems for Brownfield-type properties (both commercial and industrial) sites in northern California.
We have experience and background knowledge of the Little Lakes industrial site. SHN provided critical review of the Phase II investigations, assisted the City with stockpile characterization, performed the kiln characterization, and assisted with the demolition and disposal of the kiln materials. Key staff from those projects will bring their knowledge forward, should we be selected; they are Mike Foget, PE; Marty Lay, PE; Roland Rueber, PG; and Erik Nielsen, PG and CHG.
SHN has worked on more than 50 mill sites in northern California (8 in Arcata). SHN has provided third-party technical review services to both municipal and industrial clients for sites SHN assisted with the demolition efforts at the Little Lakes location. ranging from Brownfields facilities to former mill sites.
2 Executive Summary
We have a track record of site closures. Regulatory agencies trust our work, and we know how to chart a path toward closure. For example, for 35 CALFIRE sites, we have closed 31 of them (89%).
We create innovative and energy efficient remediation solutions. We have used numerous types of real- time data collection systems, and in one case, using an advanced analytical technique saved $2 million in further remedial action. Energy efficiency is realized by designing passive remediation techniques, such as in-situ chemical oxidation, oxygen diffusion, or passive sub-slab ventilation.
Our team’s public engagement success is supported by our work with the City’s Old Arcata Road Improvement project design charrette.
We are sensitive to limited budgets. SHN’s standard practice for Phase II site investigations is to use the triad approach to fully define sites the first time, reducing the need for additional site investigation. Our philosophy in remedial investigations is to collect sufficient data to make decisions on the appropriate remedial action or to obtain site closure. We do not “study a site to death,” but we do feel strongly that it is cost effective to collect certain types of data early in an investigation, as opposed to remobilizing later to collect this data.
Within the Arcata city limits, SHN has worked on more than 60 environmental investigations and cleanups.
3 Consultant Proposal Information
Consultant Proposal Information
Consulting Team Information The team proposed for this work is comprised of SHN Engineers & Geologists (SHN), the Redwood Community Action Agency (RCAA), North Coast Laboratories, and Fisch Drilling. All are located within Humboldt County, and all fulfill the requirements of California Small Business Enterprises.
SHN began as Selvage and Heber in 1979, quickly became Selvage, Heber & Nelson, and is now known as SHN Engineers & Geologists. SHN is a privately held corporation, with approximately 30% of employees holding stock.

4 Project Understanding
Project Understanding
The City of Arcata has identified thirty-two (32) generating potential from the City’s tax base. The parcels as Brownfield sites. The Brownfields City’s achievement in obtaining this Brownfield Assessment Grant is intended to fund preparation grant is a step toward meeting the City’s General of an updated inventory of Brownfield sites within Plan goals of encouraging infill development of City limits, conduct at least eight (8) Phase I vacant, Brownfield, and underutilized land. Once Environmental Site Assessments (ESAs), complete the sites are cleaned up, the City will be able to four (4) Phase II ESAs for hazardous materials and facilitate beneficial uses that may include two (2) Phase II ESAs for petroleum sites, and plan redevelopment to meet housing and employment remedial action at two (2) sites. Additionally, the needs without major extensions of infrastructure City is requesting a general approach and strategy and services. to complete characterization of the former Little Lake Industries site in order to prepare a Remedial We also understand the strict budget constraints Action Plan.

The Little Lakes site has been cleared of structures, so areas of concern are accessible.
5 Project Approach
Project Approach
SHN’s approach to helping the City of Arcata meet its General Plan goals is to provide environmental services in a way that will best serve the City and move these sites toward productive redevelopment.
It is our understanding that the City, working with the Brownfields Stakeholder Advisory Group (BSAG), will select sites from a city-wide inventory of contaminated sites within the city limits. The City and BSAG will identify the highest priority sites that need further investigation. SHN will conduct streamlined Phase I investigations of these sites. One important priority-setting factor will be the redevelopment potential of each parcel.
Existing Phase I and Phase II data will be used to identify priority sites that are perceived as being highly contaminated, but in reality could be brought back into productive use in the community with relatively little effort.
Recognizing that the City has $300,000 in its grant budget, and based on previous experience, we believe that a full investigation of six priority sites may not be feasible. Therefore, we will work with the City to select the top priority sites to investigate; however, the City may select some of the sites which could be cleared with minimal Phase II efforts. SHN and City staff will identify parcels that the City would like to see developed based on proximity to existing infrastructure, transportation corridors, economic development potential, or other criteria that the City and BSAG will have developed. Those site(s) will serve as a positive display to the community, enabling the City to demonstrate that work is progressing and that sites are moving toward redevelopment.
The Phase II investigations will include developing Site Conceptual Models (CSMs) that will clearly show what needs to be done to remediate these sites. At this point, we will suggest potential additional funding sources so the City of Arcata can move clean-up activities forward.
Considerable effort will be placed on public engagement and community awareness. For this task, we have teamed with the Redwood Community Action Agency (RCAA). With the City, we will conduct meetings with the Brownfields Stakeholders Advisory Group and the public so everyone knows what is being planned and why. In our experience, keeping community members informed (especially in a close-knit community like Arcata) is paramount in securing public support and cooperation. Last year, SHN and RCAA provided community outreach services for the City’s Old Arcata Road design charrette.
6 Scope of Work
Scope of Work
Task 1 Project Initiation
To initiate work on this project, SHN and RCAA will participate in the first of six stakeholder meetings scheduled for this project. The first stakeholder meeting will be used to introduce the Brownfields program and this project to the public and outline the scope and goals of the project.
SHN will obtain the inventory of impacted sites within the City and the associated GIS database that identifies potential “at risk” properties.
Task 2 Conduct Phase I Environmental Site Assessments
PHASE I ESA Sites identified during the inventory will be ranked according to level of contamination and potential for redevelopment based on the criteria established by the City staff and the BSAG. We will work with the City to identify the highest priority sites. SHN will then conduct Phase I ESAs on each of the sites that have been selected (up to 8 sites).
Our Phase I team will work closely with the Project Manager, but will be spear headed by Mr. Roland Rueber, our Lead Environmental Assessor. In addition, Roland will be backed up by Marty Lay, who has extensive Phase I experience. Marty has worked and lived in Humboldt County for more than 40 years and has considerable personal experience with the area. This team has completed hundreds of Phase I ESAs and will gather and assemble all the available information and data as recommended by American Society for Testing and Materials (ASTM) E1527-13 standard and All Appropriate Inquiry (AAI ) standards quickly and efficiently.
In accordance with the AAI standards, we will review information regarding topography, geology, hydrogeology, and soils; and conduct site reconnaissance to observe on-site and adjacent site conditions. SHN will confer with the Humboldt County Division of Environmental Health (HCDEH), the Regional Water Quality Control Board, North Coast Region (RWQCB), the California Integrated Waste Management Board (CIWMB), and others to evaluate the information gathered in Task 1. This will result in a “ranking” of the sites by potential for suspected contaminants and development potential.
Eight Phase I ESA reports (one for each site, as requested) will conform to the ASTM Phase I ESA Standards (ASTM E1527–13), and be in accordance with applicable AAI standards. The reports will include a findings section that will summarize known or suspected, recognized environmental conditions at each site. A property profile report will also be prepared for each site and submitted to City staff for review.
7 Scope of Work
We will then meet with the City to discuss the Phase I ESA findings and decide which sites need no
PHASE further investigation, and which sites have recognized environmental conditions that warrant I ESA Phase II ESAs, as well as select up to three (3) Phase II ESA petroleum sites, and up to three (3) Phase II ESA hazardous materials sites, based on prioritization criteria set up by City staff and the BSAG.
We anticipate conducting two public meetings during the Phase II investigation program to update the City and community on the progress of the ongoing site investigations. Public Meeting #2 will occur at the end of Task #2 to present the inventory, Phase I results, and sites identified for Phase II investigation.
Task 3 Conduct Phase II Environmental Site Assessments (Hazardous Materials Sites and Petroleum Sites)
Once the sites of interest have been prioritized, we would prepare the EPA-required Sampling and Analysis Plan (SAP), Quality Assurance Project Plans (QAPPs), and Health and Safety Plans (HASPs). As a cost saving measure, some elements of the QAPP and HASP can be written so they can be applied to more than one site. As part of SAP development, SHN will seek approval from appropriate oversight regulatory agencies prior to submittal to the EPA.
Upon receipt of approval of our Phase II documents (SAP, QAPP, and HASP), we will mobilize our field team to conduct the Phase II investigations. These investigations will involve the collection of soil and groundwater samples in areas containing recognized environmental contamination.
The samples would be collected using a combination of traditional and rapid site assessment technologies to maximize the amount of data that can be collected for the money spent. Generally, samples will be collected with the assistance of a Geoprobe®, backhoe, or with hand equipment. These samples will be analyzed for constituents-of-concern consistent with former land use practices. To maximize flexibility in the field, a dynamic work plan using the EPA’s Triad Investigation Approach will be used to make real-time decisions regarding sample locations and analytical methods. Test kits and hand-held instruments will be used to field screen samples, the results being used to guide additional sampling where appropriate. We may use a Geoprobe® equipped with a Membrane Interface Probe (MIP) to identify the extent of any petroleum hydrocarbon contamination or volatile organic compounds (VOCs) in the field and to help define the extent of the contaminant plume and associated geology. This technique saves time and money by reducing the number of samples required for laboratory analysis and by providing real- time definition of the extent of contamination and site geology.
8 Scope of Work
Upon completion of the Phase II work at the selected sites, a report of findings will be prepared for each site and submitted to the City staff for review and comment. These reports will summarize the key findings from the Phase I investigations and describe the Phase II sampling activities, the results of the investigation, and recommendations, if appropriate. Based on findings, some site may be eligible to request “No Further Action” from the RWQCB. Each report will be organized in accordance with EPA reporting requirements and will include a site conceptual model. SHN will then address any comments, finalize the documents, and submit final copies to the City and appropriate regulatory agencies.
Stakeholders Meeting #3 will occur at the end of Task 3 to review Phase II results and present criteria for selecting sites to pursue for clean-up efforts.
Task 4 Remediation Planning
Based on the results of the Phase II ESA investigations, SHN will work with City staff and the BSAG to select two sites for remedial action. We will prepare a Remedial Action Plan (RAP) for each site (up to two sites). The selected remedy for each site will depend upon the proposed reuse of the site, and the anticipated timeline that the City would like to see the site remediated. SHN will then prepare an Analysis of Brownfields Cleanup Alternatives (ABCA) for each site which can then be used to pursue US EPA Brownfields remediation funds.
We anticipate conducting the fourth public meeting at this time. The purpose of this meeting would be to update the community with regard to our proposed corrective action and next steps.

9 Scope of Work
Task 5 Little Lakes Industries
Our approach to the Little Lakes site is a bit unorthodox, but has been effective in unusual situations, where there is existing data of known contaminant sources. As the available data is more than 10 years old, and due to the fact that the regulators SHN was working with on the site at the North Coast RWQCB have since retired, we are proposing a different kind of strategy. Since there are redevelopment plans in place, and historical data available, it would be prudent to discuss with the oversight agency before proposing an additional course of action, to save time and valuable funds.
Our plan is to succinctly summarize the available data for the site in a technical memorandum with our recommendations for additional investigation based on the proposed re-use plans for the site. Prior work has not included the additional reuse scenarios for the site. This information would be submitted to the RWQCB, and a meeting would be requested to discuss with them a path forward (a discussion of site conditions was requested by the new regulator via e-mail dated April 4, 2016). The technical memorandum would include our recommendations for additional sampling to fill data gaps, in light of the proposed development plans. Additional sampling is warranted based on the existing data set, but we would like to tailor the investigation to the RWQCB concerns. We feel it is important to get regulatory buy-in on sites with existing data and a proposed redevelopment plan, rather than proceed with the more cut-and-dry EPA Phase I/II protocol approach for sites with no data. Following the meeting with the RWQCB, we would then prepare the EPA required SAP/QAPP and HASP for additional sampling. As such, cost estimates would be similar to those for the hazardous materials phase II investigations, but would be tailored to site conditions. After conducting Phase II site investigation activities, SHN will prepare a phase II site investigation report. We anticipate public meeting number 5 to discuss the results of the phase II site investigation.
We will work with the City to evaluate cost estimates within the scope of the grant to make sure the investigation and any remedial action at this site is appropriate for beneficial reuse. Depending on remaining concentrations of contaminants of concern at the Little Lakes site, elements of the redevelopment plan can be incorporated into the final selected remedy.
Because the regulatory requirements have changed since the Phase II investigations, (along with the regulatory personnel), an innovative approach is required for the Little Lakes site. This can all be accomplished under the grant funding, and collaboration with the oversight agency will speed up the evaluation of current site conditions, and steps necessary for additional site investigation and potential remediation and clearance for beneficial reuse. Based on phase II results, and incorporating the redevelopment plans, SHN will prepare a RAP for each site. SHN will then prepare an ABCA which can then be used to pursue US EPA Brownfields remediation funds. We anticipate public meeting number 6 to discuss the selected remedy for the little lakes site and next steps.
10 Qualifications
We understand this site is a priority and involving the Estimated Costs regulatory agency will minimize costs for additional Little Lake Industries Site investigation, potential remediation, and beneficial reuse. Action Item Costs
Depending on remaining concentrations of contaminants of Site Summary and Meeting $6,000 concern at the Little Lakes site, elements of the SAP/QAPP, HSP, and Additional redevelopment plan can be incorporated into the final $30,000 Investigation selected remedy. Because this a known site with hazardous materials present, new regulatory personnel and a Remediation Plan (if needed) $8,000 redevelopment plan, we have estimated costs, shown to the right.
Qualifications
To meet the City’s redevelopment goals, SHN has assembled a team of professionals with experience in the investigation and remediation of Brownfield sites, including many Phase I and II contaminated sites. Two of our subconsultants, Fisch Drilling and North Coast Laboratories, are also Small Business Enterprises (Fisch Drilling’s recertification is pending) and have worked with SHN on many Brownfield-related sites, including most of those we list as relevant projects in this proposal. In addition, we have teamed with RCAA to help with facilitating public meetings and community outreach.
This section describes the unique qualifications the SHN team can provide to the City. As presented herein, SHN has the demonstrated local knowledge and redevelopment experience to successfully complete this project on schedule and on budget.
Demonstrated Competence and Relevant Experience SHN provides turnkey environmental site investigation and remediation services throughout northern California. We believe our unique positioning and daily interactions with local regulatory agencies bring value to the City of Arcata, based on our following attributes:
1. SHN’s standard practice for Phase II site investigations is to use the triad approach to define sites the first time, reducing the need for additional site investigation.
2. SHN has a good working relationship with City staff.
3. SHN enjoys a close relationship with the regulatory agencies. Our constant involvement with regulatory staff allows us to navigate the maze with The triad approach uses systematic project exceptional effectiveness, which translates into less planning, dynamic work strategies, and real- time to complete projects. time measurement technologies to effectively assess and manage contaminated sites.
11
Qualifications
4. SHN has provided third-party technical review services to both municipal and industrial clients for sites ranging from Brownfields facilities to former mill sites. 5. SHN has worked on more than 50 mill sites in northern California, including 8 in Arcata. 6. SHN has worked on more than 60 environmental investigation cleanups in Arcata. 7. SHN’s philosophy toward remedial investigations is only to collect sufficient data to make decisions on the appropriate remedial action or to obtain site closure. SHN is not in the business of “studying a site to death,” but does feel strongly that it is cost effective to collect certain types of data early in an investigation (as opposed to remobilizing later to collect this data). 8. SHN and its project team are in close proximity to the sites, which means lower mobilization and travel costs than consultants from Sacramento, the San Francisco Bay Area, or Portland. Lower consultant costs mean that more funds are available to remediate the sites.
Consistent and returning clients throughout northern California and southern Oregon is evidence of our environmental services capabilities. SHN has repeatedly demonstrated its capability with regard to assessing, permitting, designing, and implementing innovative and cost-effective remediation systems. In addition to winning awards for innovative remediation projects, our projects have often resulted in substantial savings to our clients. For example, SHN is the northern California environmental engineering consultant for PALCO/ Humboldt Redwood Company (HRC), Simpson Timber Company/Green Diamond, and Louisiana-Pacific (LP). We have been providing quality, effective environmental investigations and remediation design and implementation to PALCO/HRC, Simpson/Green Diamond, and LP for more than 30 years.
SHN understands that cleaning up the sites identified in this RFQ is an important aspect of the City of Arcata’s economic restructuring plan. SHN has performed at least 50 Brownfields redevelopment-type projects over the past 10 years. These sites include commercial properties (including abandoned gasoline stations and dry cleaners), former mill sites, industrial facilities, and waterfront properties.
SHN provided high-quality, cost effective environmental services to the Division of the State Architect (DSA) for 20 years. During that time, we met every project schedule, and have always been within budget for major contracts. We will do the same for the City of Arcata. SHN is the current northern California on-call environmental and hazmat engineering consultant for the California State Department of General Services (DGS)--Real Estate Services Division (RESD). Through that contract, SHN has preformed SHN performed a natural attenuation pilot study several Phase 1 ESA’s and is working on several hazmat at a CAL FIRE site and demonstrated that projects, including 12 CAL FIRE fuel-related sites for DGS- remediation as recommended by others was not RESD. We have proven work records with these state necessary; consequently, SHN closed the site. agencies and we will deliver the same competence and care to the City of Arcata.
12 Qualifications
Prior Experience with US EPA Brownfield’s Grants Brownfields are abandoned, idled, or underused industrial or commercial properties where expansion, reuse, or redevelopment may be complicated by real or perceived environmental conditions. Our staff is familiar with regulatory processes and procedures and can navigate our clients through the Brownfields process, especially sites located in Arcata. SHN understands Brownfield redevelopment and site remediation and has the technical expertise and field capabilities to ensure a successful program.
During the last decade, SHN has participated in 12 US EPA Brownfields projects, including the following:
City of Arcata Little Lakes mills site (Targeted Phase I, and phase II USEPA cleanup grant)
Tuluwat Village Indian Island on Humboldt Bay (Three separate Grants):
○ Phase II site investigation and preparation of Remedial Action Plan (EPA Brownfield Grant)
○ Phase III remediation cleanup grant (through Humboldt County Brownfield program part of a US EPA Brownfield Grant)

○ RMT II, former Samoa pulp mill – Secured clean up grant, prepared ABCA for debris pile removal, currently preparing QAPP, HASP and bid documents for removal action
This former auto wrecking yard in Rio Dell was part of SHN’s sitewide Brownfields investigations.
14 Qualifications
Prior Local Oversight Experience with Agencies SHN works closely with the regional boards and county oversight programs throughout northern California to achieve site closure, including the North Coast Regional Water Quality Control Board (RWQCB), the Department of Toxic Substances Control (DTSC), and the County of Humboldt Division of Environmental Health (HCDEH). The representatives of those agencies know and trust our work. With access to key agency decision makers, we obtain approvals quickly and push projects forward.
As demonstrated by the table below, our performance is reinforced by our ability to reach site closure. Nothing speaks to our relationships with regulatory agencies better than navigating the process and culminating in closing a site.

In addition to the investigation and remediation projects we’ve conducted for DGS RESD, SHN has performed thousands of such projects for a variety of public and private clients. SHN’s environmental services include assessing the site through geologic interpretation of the subsurface, soil vapor monitoring, and designing and implementing systems based on specific existing data/site constraints.
However, not all sites require an active remediation as a path to closure. SHN is expert in negotiating alternative solutions with regulatory agencies. We have the experience to prove that, at many sites, natural attenuation or institutional controls are adequate to protect human health and the environment. We find the best long-term solutions for the site.
Low-Threat UST Closure On August 17, 2012, the California Office of Administrative Law approved the Low-Threat UST Closure Policy. The policy was crafted to allocate limited financial resources to high-risk sites by bringing more rapid case closure to sites considered to have a low impact to human health and water supply sources.
We have been on the leading edge of implementing this policy, which is evident by having already obtained 10 closures with 5 more pending. We understand that the City must be watchful of its financial resources, and we have a proven track record for providing cost-effective and innovative solutions by SHN prepared a low-threat UST closure evaluation at the Price Trust site in Crescent optimizing available funds and providing services to sites, both City. Activities included removal of this UST low and high risk, as comprehensively as necessary with site tank. Based on data evaluation, this site was closure as the final goal. closed.

Experience with Hazardous Material Sites and Petroleum Hydrocarbons The proposed SHN team provides a wide level of expertise working with sites that have been impacted by hazardous materials commonly found at industrial sites and mills such as wood treating agents which contained penta chlorophenol (PCP), and Dioxins and Furans, chlorinated solvents, including perchloroethylene (PCE) and trichloroethylene (TCE) metals, and petroleum hydrocarbons. SHN are experts in the environmental audits and subsurface assessments. We routinely perform soil gas surveys, soil sampling, and groundwater well installation in order to determine the extent of contamination at sites, and we employ remediation techniques, such as in situ extraction (soil vapor, sparging, and pump and treat), and chemical injection. These activities are performed at sites which are impacted by hazardous materials and petroleum products, including former and current industrial locations.
Our experience in assisting clients to identify and remediate these harmful chemicals onsite is especially relevant given that use of hydrocarbons were synonymous with most industrial sites, PCE was widely known as the cleaning solvent most commonly employed by historical industrial activities and dry cleaning establishments. Our firm is fully committed to assisting our clients with tackling this important issue.
The following list presents a brief snapshot of projects SHN has been involved with that have been impacted by hazardous materials and petroleum hydrocarbons.

Use of Innovative Technologies SHN specializes in investigating and remediating contaminated sites using simple, creative, cost-effective technology, including passive remediation, monitored natural attenuation, and the triad system. We have employed several innovative methods to obtain real-time sampling data, such as the membrane interface probe, onsite laboratories, and field test kits. Using real-time data acquisition reduces cost, accelerates regulatory decisions, and can significantly shorten the duration of your project. SHN has won awards in recognition of the quality and innovative nature of our hazardous materials and remediation work. We are proud of our record of providing our clients with timely, cost-effective site closures.
SHN developed a compost blend to treat 10,000 cubic yards of PCP-contaminated soils at a mill site. This innovation led to an approximate savings of $300,000 compared to offsite disposal.
SHN saved a client approximately $2 million by using an advanced analytical technique, the petroleum fingerprint, and re-evaluating the closure plan (developed by another consultant). SHN proved to the regulatory agency that no further action was necessary. In situations such as this, our team is proud to be responsible stewards of our client’s financial resources and we strive to employ cost-saving measures whenever available.
Considering California’s ongoing drought conditions, while working at CAL FIRE’s Washington Ridge Forest Fire Station, SHN conserved water during a well pumping test for fire suppression rather than dumping it on the ground.

From 2004 through 2014, SHN provided site investigation, design, and remediation/infrastructure design services at the Tuluwat Village site on Humboldt Bay’s Indian Island. Soil and treated timbers contaminated with elevated levels of pentachlorophenol (PCP) and dioxin/furan compounds required removal at this culturally sensitive area. SHN decided to employ 40-hour OSHA HAZWOPER-trained archeologists to conduct “hand excavation.” Through our strategy, we kept site disturbance to a minimum, to protect and preserve the cultural aspects of the site. The Wiyot Tribe won two awards for this achievement, a US EPA Region 9 Excellence in Site Reuse Award (awarded in August 2017) and an American Council of Engineering Companies Engineering Excellence Award (2013).
SHN has also provided “out of the box” solutions in regard the firm’s work on the State of California’s CAL FIRE/ DGS sites. To save money for the State, SHN works with available site resources (such as excavators, surveyors, plumbers, and electricians) instead of hiring third-party subcontractors to provide various services, which saves money for California and its taxpayers. Our ability to adapt our methodology in the field is critical for remote sites.
Energy-Efficient Remediation In addition, we are experts in implementing energy efficient remedial techniques. Mike Foget is a Leadership in Energy and Environmental Design (LEED) Accredited Professional. Energy efficiency is directly related to remediation cost, primarily through on-going operations of any remediation system, particularly pumping or venting. The following table describes several “green” techniques in which SHN is expert.
SHN’s Energy-Efficient Techniques Technique Benefit Requires less run time per day than soil vapor extraction, and can be solar Bioventing powered.
Mixes contaminated soils with fertilizer and a bulking agent ex situ to promote Composting bioremediation, and eliminates hauling offsite for disposal.
Injects ozone into the groundwater. These systems typically require less energy Ozone Sparging than traditional air sparging.
In Situ Chemical Oxidation Does not require the use of mechanical pumps, blowers, or compressors. Uses bottled oxygen to slowly diffuse oxygen into the groundwater as opposed to Oxygen Diffusion air compressors (which are used for air sparging).
Passive Sub-Slab Ventilation Requires no external power for removal of vapor intrusion hazards.
Uses grasses or trees to enhance microbial activity in soil and groundwater and Phytoremediation with trees, also works for hydraulic control of groundwater plumes as opposed to soil vapor extraction or pump-and-treat systems.
In Situ Bio-Stimulation Enhances natural biodegradation processes by addition of nutrients and oxygen.
Enhances bioremediation by the addition of known degraders of target In Situ Bio-Augmentation contaminants and nutrients and electron donors.
19 Qualifications
Injection of hydrogen peroxide reduces toxicity and is used to reduce contaminant mass by oxidizing contaminants in soil and groundwater. Hydrogen peroxide breaks down oxygen and water.
Quality Control Systems SHN uses a series of internal project management tools that enable our project managers to more easily plan and execute their assignments. A quality advisor (QA) provides guidance, support, and quality assurance to the project manager throughout each project. Together, the project manager and the QA develop a project management plan for the specific job at hand. The project management plan is used to ensure that the project manager has carefully considered and documented all key phases of the project in order to create an accurate scope, schedule, and budget. The project management plan is used as a management and monitoring tool to facilitate successful project execution.
SHN encourages our project managers to share key components of the project management plan with the client, to facilitate clear communication and understanding of project roles and responsibilities, and project objectives.
Health and Safety Protecting the health and safety of our employees, the public, and the environment is a priority for SHN. All SHN environmental staff members are OSHA-trained and certified, including 40-hour Hazardous Waste Site Operations and 8-hour Refresher courses.
SHN has assigned Kaila Benton-Vitz (a Certified Industrial Hygienist) as site health and safety officer for this project. Both she and Mr. Foget (our Principal-In-Charge) have advanced health and safety training as specified in OSHA, 29 CFR 1910.120.
20 Qualifications
Expertise and Innovation Phase I ESA’s: Our local knowledge of many of the existing contaminated sites in Arcata is based on over 30 years of experience. Four of our key team members each have more than 15 years of experience investigating and remediating contaminated sites in Humboldt County, many of those in Arcata. Of the mill sites listed in Andrew Whitney’s Brownfields master thesis, our team has worked on over 70% of the Arcata sites. We grasp the nuances of historical and sometimes unreported practices at these local mill sites, and we understand the local lithology and hydrogeology. The BSAG will not require any “ramp up” or research time needed to become familiar with Arcata and the listed sites. Both Marty Lay and Mike Foget are also experienced with site civil engineering and public works The membrane interface probe is a screening tool that infrastructure, so we can provide those aspects provides both geologic and relative contaminant data and criteria for prioritizing and selecting sites. in the field. This reduces the number of samples traditionally collected for lab analysis. With this

(MIP) technology to collect real time data during site investigations. We continue to use this approach for hydrocarbons and volatile organic compounds screening during field investigations to decrease the number of mobilizations and site visits needed, which decreases costs. For Brownfields sites, we implement the EPA’s Triad Approach, which allows the use of a dynamic workplan and has the flexibility to use real time field data; these methods facilitate defining the extent of the contaminants of concern. In addition to using the MIP, we will likely use an X-Ray Fluorescence analyzer, a nuclear device in a SHN performed a hazmat evaluation for CAL FIRE at the nuclear free zone, to screen for metals in real Iaqua Buttes lookout station in Humboldt County. time, OVA meter to screen for volatile organic Using our hand-held x-ray fluorescence analyzer, we compounds, and field test kits for other were able to acquire testing results instantly in the field instead of sending samples to the lab for analysis. contaminants such as PCP, which is typically associated with wood treatment at former mill facilities.

Qualifications
Remediation Planning: Because of the North Coast’s distances to urban centers, remediation costs are significantly higher than in other parts of the state. SHN has over 30 years experience in conducting successful remediation locally, and we have been creative by necessity to make cleanups cost efficient. We are aware that out-of-area firms that have not conducted cleanups in Humboldt County are surprised by high transportation costs, high mobilization costs, and difficulties in scheduling out-of-area contractors with whom they are familiar.
Each remediation is site specific to the contaminant of concern, time line to achieve no further action (or deed restriction), and type of reuse. We have been successful implementing a “treatment train” approach by addressing the source through removal, destruction, or isolation, then monitoring the dissolved plume to demonstrate if it is stable or decreasing, and depending on the site’s reuse, some type of cap or barrier and deed restriction. For example, at the Tuluwat Village site, we directed a removal of 10% of the contaminated soil volume, but achieved a 90% reduction in total contaminant mass.
When time and available space allow, we develop energy efficient, “low tech” solutions that are generally more cost effective than highly engineered solutions. We note that many of Arcata’s sites are former mill sites, which almost always have lots of space. If we are dealing with petroleum hydrocarbons, volatile organic carbons, or even PCP, we have successfully bioremediated sites via in situ technologies (such bio sparging) and ex situ technologies (such as composting). At several sites, we have designed and permitted passive bioventing.
We have also recommended clean up technologies that do not require any infrastructure (as side from monitoring wells) such as mobile dual phase extraction (portable high vacuum) that removes contaminated soil vapor and ground water from a source area to reduce concentrations that will allow natural biodegradation to occur. Another method without extensive infrastructure is injection of strong oxidants that break down contaminants of concern into basic elements or compounds such as carbon, water, oxygen, chloride and carbon dioxide. With metals contamination, we typically consolidate and remove materials with hazardous levels, and then design fixation or isolation of the residual metals to reduce exposure below thresholds. At the former LP pulp mill, we will screen the debris piles with our XRF analyzer to determine the concentrations of metals in the debris; materials that are acceptable for reuse will be kept on site as a sub-base material for proposed site development projects.

SHN provided both environmental and civil engineering services while helping preserve cultural artifacts, and assisted with removal of marine debris located in the intertidal zone.
Permitting SHN coordinated all permitting with local, State, and Federal agencies required for this project. SHN conducted bench tests to identify the oxident to Brownfields Investigation Plan reduce PCP and dioxin but not to impact the cultural midden. SHN aided in the preparation of the remedial action plan and environmental documentation for this site under the direction of the EPA. We negotiated with the California Regional Water Quality Control Board to protect and preserve the cultural aspects of the site while removing a minimal volume of the most impacted soil.
Treatability Study SHN helped the Tribe identify additional funding for the bench-scale treatability study that determined the soil can be further remediated by means of a shallow application of In Situ Chemical Oxidation (ISCO) formulation, without adversely impacting the shell mound and other culturally sensitive materials. A comparison of soil analytical results from co-located pre- and post-ISCO soil samples, indicates that the ISCO solution was effective in reducing concentrations of COCs.

Investigation and Remediation at Former LP Pulp Mill, Samoa, CA (1997; 2009-Ongoing)
Project Relevance Local former mill site Chlorinated solvents & petroleum hydrocarbon contamination Preparation of feasibility studies Preparation of plans and specifications Selection and development of remedial action Consultation with State and Federal regulatory agencies
This pulp mill facility operated from 1964 to 2008, and is currently inactive. The facility used chlorine prior to conversion to hydrogen peroxide (1994) for bleaching pulp. In 1994, LP converted the pulp mill into a totally chlorine-free operation. Site structures and process equipment remain, with the removal of above ground storage vessels beginning in 2011. The EPA recently completed the transfer and removal of approximately two million gallons of process chemicals, removed sludge, and performed tank demolition.
In 1997, SHN completed an initial site investigation which indicated the presence of petroleum hydrocarbon, chlorinated halocarbons, metals, and resin and fatty acids in groundwater at various locations around the site. SHN subsequently conducted a tidal influence study that indicated that groundwater flow beneath the eastern portion of the site was affected by daily tidal fluctuations in Humboldt Bay. Although low-level groundwater contamination was found beneath the site, SHN successfully argued to the RWQCB that no remedial action be performed at the site and that only groundwater monitoring be These images present a conceptual representation of conducted. demolition phases at the LP pulp mill site.

Remedial Implementation for Northcoast Environmental Center, Arcata, CA (2011-Ongoing)
Project Relevance Brownfields site located in Arcata In situ chemical oxidation remediation Borings for soil/groundwater sampling Two infiltration galleries for the application of sodium permanganate Passive remediation
Located in Arcata, the subject site has contained various businesses since the 1930s, including a dry cleaning operation during the 1970s and early 1980s. A heating-oil tank was removed from the property and, in 2005, the County of Humboldt closed the site with regard to impacts from fuel release. The 2005 targeted Brownfields assessment phase II report identified that soil and groundwater at the site were impacted by tetrachloroethylene (PCE). PCE is the most commonly used dry cleaning solvent and a common contaminant that adversely affects soil and groundwater quality. Because exposure to PCEs can cause serious illness and poses a significant risk to the adjacent areas at large, the property owner needed to find a way to remediate the site to satisfy RWQCB requirements.
In May 2011, SHN supervised the installation of five borings for the collection of soil and groundwater samples for treatability testing for the purpose of collecting data to evaluate and develop an appropriate in situ chemical oxidation (ISCO) remediation program for the site. Later that year, approximately 40 cubic yards of PCE- SHN installed a passive soil vapor extraction trench to remove VOC’s from the shallow subsurface located impacted soil just south of the former heating-oil next to a building at the NEC site. tank was extracted from the site.

SHN conducted chemical injection on April 17 and April 2012. As part of the chemical injection, approximately 2,700 pounds of sodium permanganate solution were injected into more than a dozen temporary injection points at the site. The use of temporary injection points allowed SHN to place chemicals directly into targeted locations where elevated chlorinated hydrocarbons existed. The use of temporary injection points also allowed SHN to place ISCO chemicals directly into low- permeability zones in the site soils where recalcitrant compounds (such as PCE) tend to Application of permanganate solution by way of Geoprobe temporary injection points. reside, further enhancing the effectiveness of the ISCO remediation zone.

SHN’s Phase I team gathered and report progress on the ongoing site investigations, assembled all the available information and data as present the inventory and Phase I results, review recommended by ASTM and All Appropriate Phase II results, and finally to update the Inquiry (AAI) standards, which resulted in a community with regard to our findings “ranking” of the sites by potential for suspected (contaminants of concern and the next steps). contaminants and development potential. Phase I ESA reports (one for each site) conformed to the ASTM Phase I ESA Standards, in accordance with applicable AAI standards. The reports summarized known (or suspected) recognized environmental conditions at each site. SHN then met with the City to discuss the Phase I ESA findings and decide which sites need no further investigation, and which sites had recognized environmental conditions that would warrant Phase II ESAs.
Once the sites of interest had been prioritized, SHN SHN used a hand auger to collect soil samples from prepared the EPA-required work plan, Quality areas with limited access. Assurance Project Plans (QAPPs), and Health and Safety Plans (HASPs). As another cost saving measure, some elements of the QAPP and HASP were written so they could be applied to more than one site. Upon receipt of approval of Phase II documents (work plan, QAPP, and HASP), SHN conducted the Phase II investigations (collection of soil and groundwater samples in areas containing recognized environmental contamination). SHN used a Geoprobe® equipped with a Membrane Interface Probe (MIP) to identify the extent of petroleum hydrocarbon contamination in the field and to help define the extent of the contaminant SHN used MIP for field screening of sample locations during the Rio Dell Brownfields investigations. plume and associated geology. The report of findings for each site summarized the key findings from the Phase I investigations and described the Phase II sampling activities, the results of the Project Reference investigation, and recommendations, if Kyle Knopp, City Manager appropriate.

Halvorsen (Old Carson) Mill Site Phase I and Phase II Environmental Site Assessments, City of Eureka, CA. Assisted in the preparation of a detailed Phase I ESA of this former lumber mill and foundry site. The 14-acre site is situated adjacent to Humboldt Bay
and has been developed since the mid-1800s. The Phase I research identified previously unknown sources of potential contamination that were subsequently investigated. Three levels of Phase II investigation were developed and presented to the client. Each level of investigation was progressively more comprehensive and intended to provide a more accurate assessment of potential clean up costs. SHN installed 54 test pits and 5 temporary well points to determine the lateral extent of soil and groundwater contamination at the site. Both organic and inorganic constituents were detected at the site. The sawmill area contained petroleum hydrocarbons in various locations as identified by the Phase I investigation. The foundry portion of the

Conducted a Phase I ESA for the Orick Mill “A” facility, and for the former CA #2140 Simonson Lumber mill located in Smith River, CA. Site assessments were conducted for the purpose of due diligence. The Orick mill is being demolished; therefore, SHN conducted a survey for asbestos containing materials, which were identified and abated prior to demolition activities occurring. Phase II soil and groundwater
investigations have been conducted on the Smith River truck shop and mill site parcels, and some Phase III work has also been completed. These assessments and studies are being completed to prepare specific parcels for sale and reuse.
Price-Costco, Eureka Site Development Project, Eureka, CA. Conducted Phase I research and evaluation, Phase II sampling and site characterization, and Phase III site mitigation of approximately 18,000 tons of contaminated soil. This nine-acre site had many probable sources of petroleum hydrocarbon contamination, including underground and aboveground fuel storage tanks, a fire training facility, an asphalt batch plant, a sewer treatment plant, a race track, and uncontrolled fill. In order to
characterize the site properly, SHN collected 160 soil samples from 62 test pits/sampling locations. SHN also installed seven groundwater monitoring wells to characterize groundwater conditions beneath the site. Subsequently directed the excavation of contaminated soils from 11 areas on site and assisted with oversight of the treatment of contaminated soils with an on-site thermal desorption treatment unit. Assisted with on-site sampling of excavations, and oversight of excavation and treatment of soils with using a mobile laboratory. Due to the rapid pace of the project
(the COSTCO store was under construction), SHN phased the cleanup to first clear the building pad area, and conducted cleanup activities 24 hours a day, 7 days a week. The treated soil was backfilled and compacted into the excavations. After further groundwater characterization and subsequent intrinsic bioremediation, the site achieved regulatory closure.

Re: Letter of Reference for SHN Engineering
He’ ba’ lo’ Mr. Crider,
For time immemorial the Wiyot Tribe has been stewards of its ancestral natural resources, including the waters of Wigi, known today as Humboldt Bay. As you are aware, we have recently completed an ongoing cleanup on the Tribe’s sacred Tuluwat Village midden on Indian Island. This multiyear project has involved a complex array of funding, permitting, project management, and implementation. SHN Engineering has been involved with the Wiyot Tribe since early in the process and has assisted with all aspects of the project. They have assisted with identifying and applying for funding, including through the Humboldt County Economic Development Division and US EPA, ; preparing and applying for permitting and managing permit compliance for multiple agencies including the CA Coastal Commission, State and Regional Water Boards, Army Corp of Engineers, and more; identifying innovative solutions such as cost-savings measures for dioxin testing and treatment; prepared technical reports; and have helped the Tribe manage multiple contractors to see the project through to fruition.
Through all of this work, their commitment to the success of the project and the health of the Humboldt Bay environment has been very apparent. Work was always completed in a timely manner and they were always very responsive to us as a client. I can wholeheartedly recommend their services and would be happy to answer any other questions regarding the quality of their work.
Čawokš,
Stephen Kullmann Wiyot Tribe Natural Resources Director
