Dave Cook Discusses Consent Decrees, Cleanup and Ecology’s Healthy Housing Program for Contaminated Sites at the WA Brownfields Conference on May 30, 2019

On May 30, Aspect’s Dave Cook will co-present on affordable housing development from the environmental consulting perspective at the Washington State Brownfields Conference in Spokane.

Brownfield properties represent opportunity. Dave will talk about innovative ways to turn blighted property into affordable/work force housing. Aspect’s first-of-its-kind work on the Mt Baker Housing Association’s Gateway project in the Mt Baker/Rainier Valley neighborhood in Seattle has become an example of what is possible. Mt Baker Housing Association (MBHA), as a non-profit, took on a significantly contaminated site to redevelop as affordable housing where the cost of the cleanup is more than the value of the five properties combined. Dave will join Scott O’Dowd of Ecology, Conor Hansen of MBHA and Mike Dunning of Perkins Coie to describe how these properties were purchased, investigated, liability managed, and the cleanup financed—all keys that made this pioneering project successful and sparking the State’s new Healthy Housing program .

Andrew Austreng, Jon Turk, and John Warinner will be presenting Thursday and Friday May 2 and 3rd at the American Water Works Association (AWWA) ‘River Runs Through It’ 2019 Section Conference in Vancouver, WA. Andrew will present on the Othello, WA Aquifer Storage and Recovery project; Jon Turn will showcase groundwater recharge strategies for a unique project involving reclaimed water in Kitsap County; and John Warinner will discuss challenges and opportunities of managing groundwater across two state lines in the Walla Walla subbasin.

The annual AWWA conference is one of the largest conferences for water professionals in the Pacific Northwest.

New GIS Tool Helps Remove Barriers to Salmon Habitat Connectivity

Clean, cold water. Lush riparian vegetation. Gravels for spawning. These are some of the elements that create healthy habitat for salmon. The Upper Columbia region has some of the best in the Pacific Northwest. Unfortunately, not all of this habitat is within the salmon’s reach. Removing barriers such as culverts and dams is a top priority for salmon recovery goals, but there are thousands of barriers, limited resources to remove them, and a diverse group of stakeholders with issues to address. What everyone wants to know first is: how do we decide WHICH barriers to remove?

Instream barriers such as culverts like this can limit fish passage to available habitat.

Enter a New Tool for Fish Habitat Decision Making

In partnership with the Cascade Columbia Fisheries Enhancement Group, the Upper Columbia Salmon Recovery Board, the Upper Columbia Regional Technical Team (RTT), and a technical steering committee, Aspect created a GIS-based decision support tool that summarizes the overall quality of ecological conditions surrounding each instream barrier within the Wenatchee Basin. This custom spatial model provides insight into critical questions regarding barrier-removal priority:

  • Is there habitat available upstream from the barrier that salmon currently cannot access?

  • Is that available habitat of sufficient quality for salmon?

  • Is there known fish usage near the barrier already?

  • Are there barriers downstream blocking fish access?

This prioritization tool provides salmon-recovery stakeholders with a common approach to answer these questions. The variables under consideration at a barrier—upstream habitat quality, local stream temperature, connectivity to other barriers, etc.—each receive a score. Those scores are then added up to a total priority tier ranking for that barrier. By assessing each barrier through this scoring process, we’ve created an actionable apples-to-apples comparison of habitat benefits associated with barrier removal.

A preview of barrier removal ranking priority data.

A preview of barrier removal ranking priority data.

A Tier 1 ranking indicates the top priority for removal, indicating more biological benefit gained from a barrier’s removal. Tier 4 ranking is the lowest priority ranking, indicating little biological benefit gained from a barrier’s removal. UCSRB and the RTT use these categories to guide decisions on proposed project funding. The rankings are updated as available data sources improve.  Preview the results HERE. This tool will allow stakeholders to align and coordinate their barrier removal work towards the larger common goal of salmon-habitat connectivity within the Upper Columbia and throughout the state.

MTCA Turns 30

Happy 30th Birthday to the Model Toxics Control Act (MTCA)­—Washington’s citizen-led law put in place to help cleanup over 7,000 sites statewide. Those thousands of cleaned up sites have led to a cleaner environment, better human health, and thriving communities. The interpretation or implementation of it has had some bumps and difficulties, but on balance MTCA has been very beneficial to the common good and, as the video discusses, an example nationally of a successful cleanup process. As a firm that helps clients interpret and cleanup sites, Aspect is proud to be a part of its effect on all of us.

Checkout Ecology’s short video for the history and highlights of this important and innovative law.

Carla Brock Chairs WA’s Geologist Licensing Board

Associate Geologist Carla Brock was recently appointed as Chair of the Washington State Geologist Licensing Board by her fellow board members. The board is comprised of six licensed geologists and one public member and is responsible for licensing geologists; updating the rules and regulations governing the practice of geology in the state of Washington; and investigating violations of the regulations. Carla is starting her second year of a four-term appointment to the board.

Washington State is a member of the National Association of the State Boards of Geology (ASBOG), which develops standardized written examinations for administration by the 32 member states and Puerto Rico, assessing qualifications of applicants seeking licensure as professional geologists. In addition to her duties on the state board, Carla participates as a Subject Matter Expert (SME) on ASBOG’s Council of Examiners (COE). The COE is comprised of SMEs from across the country and convenes twice a year, immediately following administration of the tests, for examination development and validation workshops. The COE spends two days reviewing test questions and answers to maximize the fairness and quality of the examinations as measures of competency. The COE is not all work, each meeting includes lunchtime presentations by local experts on interesting and relevant topics and a third day in which local experts lead a geologic field trip.

Carla just returned from the spring COE, which was held in Nashua, New Hampshire and is proud to support ASBOG but also enjoys the opportunity to connect with colleagues from across the country and to learn about local geology.

Talking Field Data Collection at 2019 OCEAN Connect Conference on April 11

Over the past decade or two, technological advancements have presented opportunities to streamline field data collection. However, migrating field staff to a paperless workflow requires more than choosing the right software and hardware.

On April 11, Aspect’s John Warinner and Robyn Pepin will cover this topic and give tips on how to effectively convert field data collection from paper to digital process at the 2018 Oregon Conservation Education and Assistance Network (OCEAN) Connect Conference in Sunriver, Oregon.

Key areas of the presentation will include:

  • Overview of commercial off-the-shelf software and reporting systems

  • Case studies and lessons learned by Aspect’s field and data teams

  • Successful talking points to convince decision makers

Taylor Dayton Presenting on Water Rights as Mortgage Assets to NAPMW - April 12

Taylor Dayton, Water Resources Engineer

Taylor Dayton, Water Resources Engineer

Aspect Water Resources Engineer Taylor Dayton, EIT, will present at the National Association of Professional Mortgage Women (NAPMW) LPO Seminar in Lake Chelan on Friday, April 12, 2019. The presentation will explore water rights as assets in the mortgage industry - how water rights are created, moved, lost, and valued. Taylor will also speak to the recent Hirst decision and “fix” and how it affects eastern Washington water rights and development.

The State’s Longest-Running Water Rights Adjudication is Coming to an End

In 1977, James J. Acquavella’s name was listed first on the summons when Ecology filed a petition for an adjudication to determine the legality of all claims for surface water in the Yakima River Basin – birthing the Ecology v. James Acquvella, et al water rights case. Forty-two years and 2,500 claimants and interested parties later, it is coming to a close. Some takeaways for this milestone moment in Washington state water management are:

  • Starting in 1977, the Department of Ecology v. Acquavella adjudication is the longest-running general adjudication in state history, determining the validity and establishing priority of surface water claims in the Yakima Basin.

  • With the issuance of the Final Decree by Yakima County Superior Court, water right holders in the Yakima Basin will finally have certainty over the authorized quantities and purposes and places of use of their water right claims.

  • Adjudicated water right certificates will be issued by Ecology for all claims determined by the Court to be valid; water right holders will no longer need to get approval of the Court to complete a change or transfer a water right, but instead file applications with Ecology like everywhere else in the State.

  • During the adjudication, stakeholders in the Yakima Basin continued to lead the state in providing innovative approaches to water resource management challenges, including early adoption of water banking and mitigation markets to ease permitting of new water rights, and development and implementation of the Yakima Basin Integrated Plan.

Aspect has worked on a variety of Aquavella claims over the decades – including hundreds of due diligence water right evaluations; helping buyers/sellers move and change these rights; and developing water banks through the State’s Trust Water Right Program to support efficient transfer of existing rights and permitting of new, mitigated water rights.

Recognizing World Water Day

Water is a scarce resource for many worldwide. The United Nations has designated today, March 22nd, as World Water Day to raise awareness of the billions of people—about 3 in 10—living without safe water. As earth science professionals, this message strikes a chord with Aspect staff who spend many of our work hours towards helping clients find, produce, and manage water. Supporting NGO goals – like the UN’s “water for all by 2030” – is important to us. Whether it’s organizations like UN or Engineers Without Borders USA, please join us in learning more about these worthy causes.

International Women’s Day at Aspect

Aspect celebrated International Women’s Day with a gathering and conversation sparked by a video produced by Lean In as part of their 50 Ways to Fight Bias program. The video defined the common biases women experience at work and beyond:

  • Performance (underestimating women’s experience and performance)

  • Attribution (women get less credit for success, more blame for failure)

  • Likability (been agreeable can be seen as less competent, while being assertive can make one less likeable)

  • Maternal (choosing to become a parent can be seen has having less commitment to career)

  • Affinity (people tend to gravitate towards people who are similar in appearance and background; when only white men hold positions of power, this has a negative effect on women and people of color)

  • Compounded discrimination + Intersectionality (the compounding affect of bias due to gender, race, sexual orientation, disability, and other attributes)

Thirty-three percent of Aspect’s staff of 107 are women, including 15 percent of Aspect’s technical/engineering staff, which is slightly higher than the statewide percentages for female engineers –11 percent in Oregon and 12 percent in Washington. In 2018, 21 percent of our technical hires were women.

The theme for International Women’s Day 2019 was Balance for Better, encouraging action towards creating a more gender-balanced world. Some of our staff modeled the “Balance for Better” pose to show our commitment to finding that balance.

The $82 Million Icicle Creek Subbasin Watershed Plan Hits a Milestone

This Seattle Times article provides an in-depth look at the complex mix of aging alpine dams, world-renowned wilderness area, and the potential of changing climate patterns in the Icicle Creek Subbasin. The spotlight’s on this North Central Washington region as the 6+ year Icicle Creek Subbasin strategy hit a recent milestone with the release of the project’s Programmatic Environmental Impact Statement.

Since 2012, Aspect has been the facilitation and technical lead for this effort, serving a broad working group of city and county agencies, tribes, fisheries, irrigators, and the community. The overall program is designed to improve instream flows, assist in agricultural sustainability, and provide for local domestic growth beyond the year 2050 at an investment of $82 million over the next 10 years.

Tales from Bertha: Till, Fill, and Dewatering

As Seattle weathers the close of one historic stretch of Highway 99 and awaits the opening of a brand new one (at the time, the largest soft-ground tunnel bore in the world), we’re recapping a tale that played out in connection to one of the more dramatic milestones of the tunneling project: Bertha gets stuck.

In December 2013, the mega tunnel boring machine known as Bertha overheated and broke down 1,000 feet into its journey. Eager to keep the project moving, crews working for Washington State Department of Transportation (WSDOT) quickly designed and excavated a deep rescue shaft to get in front of the stuck machine and repair it. It was a complicated effort to drill down to Bertha considering the unique geology and human history that has defined Seattle’s waterfront.

How an Inch of Displacement Can Cause Trouble

Stabilizing the ground to create the 130-foot-deep shaft required a significant amount of dewatering [1] that had to be done quickly. This dewatering caused the surrounding soils to settle much more than was anticipated from the planned tunnel construction—the settlement reached over a wide half-mile radius, and about an inch in some places, and even more than that close to the shaft.

An inch may not seem like a lot, but for the underground maze of City of Seattle (City) utility infrastructure, including aging, brittle water and sewer lines (some over 100 years old), any additional settlement was problematic. This unforeseen settlement was enough to trigger an expedited program to assess and replace the utilities where risks were unacceptably high. The City, in need of expertise on local geology, hydrogeology, tunneling, and soil behavior, brought on Aspect to investigate problems resulting from the rescue shaft construction and help design repairs.

The aerial image of the Seattle waterfront shows locations of satellite radar altimetry points TRE Altamira used to measure precise changes in ground surface elevation from May 2014 through February 2015, which included the period of Bertha rescue shaft dewatering. The colors of the dots represent the cumulative change in elevation, with hot colors showing subsidence and cool showing uplift. The orange and red areas show the broad pattern of ground subsidence associated with the shaft dewatering. For more information on this technology, visit TRE Altamira.

Aspect’s role was four-fold: determine what parts of the City’s infrastructure were being most affected by the settlement; assess vulnerability of other areas further along the tunnel route; assist with geotechnical engineering recommendations for replacing infrastructure damaged by the settlement; and help the City understand the cause of the settlement.

Till + Fill + Development = Complex Subsurface Challenges

Our investigation started with an extensive review of the waterfront’s underlying geology. Deep beneath the City lies a complex history of multiple glacial advances and retreats, separated by long interglacial periods. Sediments from glaciations include tills, layers of glacial lake and marine silts and clays, and sheets of glacial outwash sand and gravel. These glacial soils are interbedded with floodplain silts and sands and gravelly channel deposits transported by rivers flowing from the surrounding mountains, including lahar deposits (large volcanic mudflows) from as far away as Mount Rainier.

These strata were deposited in more-or-less horizontal and generally orderly ways, then subsequently compressed and compacted by repeated advance of glacial ice sheets. In the Pioneer Square area, a present-day look at the resulting stratigraphy is, however, far from orderly, due to its setting within the Seattle fault zone. This zone of tectonic compression repeatedly ruptured during prehistoric earthquakes, and much of the strata are now sheared, tilted, overthrust, and truncated. All of this was then overlain by weak estuary, beach, and tide flat deposits—and then extensively modified by humans.

This map shows the rescue shaft – and the southern portion of the tunnel route – in or below what was formerly the beach and tide flats of Elliott Bay. Pioneer Square was a tidal marsh area. These areas were infilled over the century with sawmill wood waste and soil fill, making the ground throughout the (now) Pioneer Square area both geologically and historically complex.

A major part of Aspect’s analysis focused on the location, thickness, and nature of the weak and shallow soils draped above the strong glacial soils, intertwined with the historical changes that occurred as Seattle developed its waterfront. The Pioneer Square area was a small upland Native Americans had lived on for millennia. Occidental Square was a shallow coastal lagoon, and most of the area south of King Street was tide flats. As timber and shipping industries flourished in the 1800s, much of the waterfront was developed with piers and trestle bridges, then filled with sawdust and wood waste from waterfront mills and soft muck sluiced from nearby hills.

On top of all that, roads, sewer lines, water lines, and buildings were constructed on the new ground. Not surprisingly, these weak fills have settled over time, resulting in bumpy roads, tilted sidewalks, and tall curbs in the Pioneer Square neighborhood. But these same soils were also highly susceptible to further consolidation when the water table was rapidly lowered by the Bertha rescue shaft dewatering.

Historical Record Sleuthing

To assess the areas of vulnerable underground utilities, we dug into the historical records—maps dating from the original land surveys of Seattle to locate the original shorelines, and previous drilling investigations going back decades to reveal the subsurface data. Aspect compiled soil records of hundreds of borings and wells to develop a database that could be mapped in three dimensions and used to identify the areas where weak soils were present. When combined with the City’s utility maps, Aspect’s weak-soils map allowed the City to easily spot areas where weak soils and vulnerable infrastructure overlapped.

Aspect also assisted the City in pursuing remote surface elevation surveying techniques including use of synthetic aperture radar (InSAR), a satellite-based radar distance measuring technique that permits detection of precise changes in ground surface elevation over time. These studies looked at time-series analysis of data beginning well before tunneling started through shaft dewatering and continuing to the time of the study. They showed an unmistakable correlation between rescue shaft dewatering and broad areas of ground settlement.

Dewatering: The Science of Making a Wet Excavation Dry

Dewatering the excavation required pumping, but at a rate and depth to keep water pressure low (too high could risk “blowing out” the bottom of the 130-foot-deep shaft). There are two aquifers beneath the rescue shaft site and Pioneer Square area – one shallow and one deep. Because the shaft bottom sat in the “deep” aquifer, pumping targeted that aquifer, which was thought to be confined from the shallow aquifer and the vulnerable utilities sitting above it.

However, because settlement happened in the shallow aquifer area, Aspect’s forensic analysis looked at answering several questions: how susceptible are the utilities to pumping a deep aquifer? Does pumping the deep aquifer cause dewatering of the much shallower aquifer? And if so, does pumping the deep aquifer or dewatering the shallow aquifer cause most of the settlement that the City was observing? Understanding the hydrogeologic connections between pumping the two aquifers and the net effects of dewatering on soil behavior required multidisciplinary consideration of many factors.

This graph from TRE Altamira shows the elevation of a single point on the map near the area of greatest ground subsidence. The dots show the date of the satellite pass, and the elevation difference from the baseline series. The sharp drop in elevation between October and December 2014 corresponds to the period when shaft dewatering began. These satellite altimetry data correlated well with elevation control data collected by others using traditional on-the-ground surveying methods.

To understand the amount of shallow dewatering that had occurred, Aspect developed a comprehensive groundwater monitoring program that instrumented existing wells to collect data while the dewatering pumps were running. Then, once the pumps were shut off, before and after comparisons of water levels could be made to see the changes brought on by dewatering. Data collection continued until dewatering had ceased and groundwater levels had returned to normal.

Fixing the Faults Caused by the Fault

Ultimately, the project team concluded that there had been localized impacts to the shallow aquifer that were related to pumping of the deep aquifer. Some of those impacts were the result of leakage from the shallow aquifer downward along the outside of the Bertha rescue shaft, and some from leakage between the shallow and deep aquifers that occurred along zones of disrupted strata that the Seattle fault created to form the complex geology below Pioneer Square. The data collected by our team provided strong support that the Bertha shaft dewatering caused enough settlement to require replacement of vulnerable utilities. This led to a program in 2015 to replace the large water main buried below Western Avenue, with Aspect providing the geologic analysis used for the design. The drive along Western Avenue is now much smoother, and the section of new water main is now less vulnerable to the next big construction project or major earthquake.

Ironically, while past activity along the Seattle fault was largely responsible for the complex hydrogeology that made dewatering the Bertha rescue shaft a challenge, it was concerns about future rupture of the Seattle fault (or one of the other regional faults) that triggered replacing the Viaduct with the tunnel to begin with. This in turn led to the rebuilding of the waterfront seawall and reconstruction of Pier 62.

As some Aspect geologists are fond of saying – “geology explains everything.” With a site as complex as the Seattle waterfront, it takes an expert “read” of the geology and a skilled team of geologists, hydrogeologists, and engineers to inform design for projects that make Seattle safer and better for the future.

The Waterfront’s Next Chapter – Highway 99 Tunnel

While the water main beneath Western Avenue was being replaced and groundwater monitoring continued, WSDOT crews had Bertha repaired and chugging along beneath the city, breaking into daylight near South Lake Union in April 2017. Seattle now awaits the opening of the tunnel Bertha cleared that will move traffic through the complex web of geology, hydrogeology, infrastructure, and development that makes up the Seattle waterfront.

Environmental Consulting Lessons Learned from the World of Analytical Chemistry

tech excange logo white.jpg

The story of environmental consulting projects often start with what the laboratory results tell us. However, all results are not created equal, and it’s important to know the big picture – site subsurface conditions, regulatory criteria, and chemistry principles – when uncovering culprit contaminants.

At one of Aspect’s recent, ongoing Technical Exchanges, Staff Scientist Andrew Yonkofski invited Mike Erdahl from Environmental Laboratory Friedman and Bruya to discuss the role of analytical chemistry in environmental consulting, including general petroleum chemistry, gas chromatography, and interpreting those results. Part of the discussion was focused on an Aspect-specific case study from a Seattle-area waterfront site. This site presents a unique look at how organic matter in the subsurface can affect results from the NWTPH-Dx analysis.

Lessons learned from the talk included:

  • Common petroleum hydrocarbon mixtures, such as gasoline and diesel, contain thousands of unique organic compounds. The NWTPH-Gx and NWTPH-Dx analytical methodologies attempt to capture the wide range of organic compounds found in petroleum hydrocarbon mixtures.

  • While the laboratory provides a reproduceable, quantifiable number for total petroleum hydrocarbon (TPH) results, those results often need to be interpreted in light of the chromatographic results. For instance, the higher boiling end of gasoline overlaps into the diesel-range. As the gasoline weathers, the proportion of material in the diesel range increases in relation to the total TPH value. Qualifying the diesel results as overlap from gasoline contamination can reduce the number of site-specific contaminant of concerns.

  • Likewise, results using both the NWTPH-Gx and NWTPH-Dx methodologies can sometimes include organic compounds from natural sources including degradation of organic material in the subsurface.

  • To properly characterize a site, environmental consultants must use multiple lines of evidence to determine the nature and extents of contamination. This includes interpreting analytical results and the associated chromatograms in the context of the historical site use.


This chromatogram illustrates how gasoline can overlap into the diesel-range. The diesel results reported by the lab do not indicate a separate diesel release from the gasoline release but rather illustrate how gasoline can overlap into the diesel-range as the product becomes weathered in the subsurface.

This example shows what a chromatogram may look like when there are multiple sources (both gasoline and diesel) present in a sample.

James Packman Talks Interdisciplinary Skills and Water’s Role in Urban Environmental Planning to UW Class

Senior Hydrologist James Packman recently presented to “Planning as a Profession,” a senior-level urban planning class in the College of the Built Environment at the University of Washington. The nearly 30 students come from different majors and career trajectories—among them are future architects, landscape architects, city planners, urban designers, real estate professionals, construction managers, engineers, environmental scientists, and more.

James Packman, Senior Hydrologist

James Packman, Senior Hydrologist

James’ presentation, entitled “Environmental Skills, Water Resources, and Urban Planning,” gave a holistic view of environmental considerations in urban planning—from the skills and interests that lead a person to the profession and the different disciplines working in the industry to the laws and regulations that drive project design, permitting, and building and examples of water-focused planning. His overarching message focused on interdisciplinary skills, and he gave examples of Aspect projects where collaboration between disciplines was vital to address the environmental elements.

For example, the Waypoint Park project along Bellingham’s shoreline incorporated coastal geology, hydrogeology, stormwater management, civil and geotechnical engineering, landscape architecture, habitat restoration ecology, and more to reclaim a contaminated former industrial site to an urban waterfront park.

Waypoint Park Before and After Construction
City of Bellingham’s Waypoint Park incorporated many environmental planning steps to turn a former industrial site into an urban waterfront park.

James also introduced the practical side of business consulting, or how people and firms pursue and win public work, and walked students through the Request for Qualifications / Request for Proposals process. His key message for being on winning teams is that it requires networking in and outside of one’s discipline and forging relationships with public agency staff to learn their needs.

He ended by going over a homework assignment about the State Environmental Policy Act (SEPA) checklist process and its key role in urban planning projects. The homework reinforced the variety of environmental disciplines—geology, hydrology, archeology, botany, wildlife biology, engineering, and more—along with professional skills—technical reading comprehension, writing, project management, public speaking, quantitative analysis, and more—that are needed to complete the checklist.

James will present to a new set of students when he returns to the class in Spring Quarter 2019.

Innovative Affordable Housing Solutions Continue in South Seattle

The Seattle City Council recently approved the 2nd Redevelopment Opportunity Zone (ROZ) in Seattle’s history for the 700-unit Grand Street Commons housing development near the future Judkins Park light-rail station. The ROZ designation means that this innovative $20 Million private/non-profit partnership (Lake Union Partners and Mt. Baker Housing, respectively) now has direct access to state funds to build a 700-unit development—with about half of those units earmarked for affordable housing. These 350 future units, together with the 160 units planned at The Maddux (the City’s first ROZ zone near the Mt. Baker light-rail station), brings 500+ ROZ-designated affordable housing units coming online in the next five years in South Seattle.

The 700-unit Grand Street Commons is a unique private/public partnership, where approximately half the units will be affordable housing. The cleanup for this brownfield site is being led by Aspect and funded by a new approach to access money specifically for affordable housing projects.

Aspect, with law firm Perkins Coie, has helped Mt. Baker Housing pioneer this ROZ model to unlock state-backed grant funding in a first-of-its-kind model. Recognizing this success, the state introduced the Healthy Housing Program this fall– earmarked specifically for affordable housing developers looking at restoring land at brownfield sites.

Reducing Risk and Uncertainty: A PCE Site, a Model Remedy, and an NFA

No Further Action (NFA) determinations are Washington state’s sought-after finish line for regulatory closure of contaminated sites. An NFA is often the stepping stone for a property owner to secure financing for development of their property and alleviate concerns that their property won’t be put to productive use. NFAs are not easy to get—particularly for former dry cleaner sites, where perchloroethylene (PCE; a dry-cleaning solvent) is a common culprit that can keep a property in regulatory limbo and cause cleanup timelines to be counted in years.

Not a Typical Cleanup: Applying a Model Remedy at a Chlorinated Solvent Site

Aspect had a recent success story where we helped a client achieve an NFA by pursuing site closure through Ecology’s Initial Investigations program using a Model Remedy approach. The premise of this approach is that if you can completely address or clean up a release upon discovery, then you may be able to request an NFA at the initial investigation/reporting stage, thereby circumventing the Voluntary Cleanup Program process.

Identifying and excavating the contaminated soil from inside the store led to a successful No Further Action determination for the Site.

Identifying and excavating the contaminated soil from inside the store led to a successful No Further Action determination for the Site.

The project site, located in Kent, was a former dry cleaner with PCE impacts limited to shallow soil around the dry-cleaning machine. Following Aspect’s Phase I/II ESA investigation as part of a pending property transaction, we implemented a cleanup action after our client purchased the property. The space inside the store was limited, and the excavation was surgical. Confirmation soil sample results following the excavation were below Model Toxics Control Act (MTCA) Method A cleanup levels. Instead of entering the VCP and facing delays with Ecology’s backlog of VCP sites, we instead reported the release to Ecology within the framework of a Remedial Investigation and Cleanup Action Report, with the completed excavation and off-site disposal of contaminated soil presented as a model remedy.

Reducing Risk and Uncertainty

After follow up discussion and negotiation with Ecology’s Initial Investigations coordinator, the site recently received an NFA. Though there may not be many PCE-impacted sites where the contamination is limited to shallow soil, it pays to know the options if this is the case. Model remedies are more commonly applied to petroleum-impacted sites. However, because Aspect was on the lookout and understood the regulatory framework for achieving closure, we were able to help our client significantly reduce risk and uncertainty when weighing prospective property purchases.

The Model Remedy approach is a strategy that Aspect has used on several sites with success and, under the right set of circumstances, can be an efficient regulatory pathway for property owners seeking an NFA.

New Seattle Address. Same Focus on Earth Science and Engineering.

As we near 20 years in business, Aspect has moved its Seattle office to a new address and bigger space in Seattle’s iconic Dexter Horton building. Our expanding client base and growing staff—now over 100 strong across seven offices in Washington and Oregon—is driving the move.

“The Pacific Northwest is thriving and so is the demand for our earth and water services,” says Tim Flynn, Aspect’s President. “This move represents the culmination of almost two decades of upward growth driven by clients in the Seattle market and throughout the Pacific Northwest.”

The Dexter Horton building—located in the heart of Seattle—has a combination of grand architectural aesthetic with innovative modern features. The 1926 building is a historical landmark as well as LEED Gold-certified. Aspect’s office on the 5th floor was designed intentionally to provide clients and staff with a variety of ways to collaborate, including open layout areas and comfortable meeting spaces.
