Ahtna Netiye’ Makes ENR 2022 Top 200 Environmental Firms List

Ahtna Netiye’, LLC (AN) has been recognized as one of the Engineering News Record (ENR) magazine’s “2022 Top 200 Environmental Firms,” jumping 38 spots to rank at 151. This was achieved while facing the COVID-19 pandemic as well as the global economic headwinds of rampant inflation, surging commodity prices, global supply chain delays, and fuel price escalation. Despite these impacts, the Ahtna family of companies has emerged stronger than ever.

AN Chief Executive Officer (CEO) Tom Maloney remarked, “We are incredibly proud to be recognized as a leading environmental firm for two years running. This achievement would not be possible without our dedicated team’s attention to quality service, reliable performance, and consideration of each project’s environmental impact. As our company mission states, we are focused on wise stewardship of Ahtna’s lands and responsible economic growth with an emphasis on safety and respect. We will continue to provide safe and sustainable solutions for our clients.”

The Ahtna family of companies’ environmental experience spans a wide range of services, from environmental site assessments to implementation of remediation technologies and regulatory closure of sites, to utilizing the latest mapping and imaging technology for complex data analyses and monitoring. We specialize in providing the right solution to our clients’ environmental challenges to ensure mission and operational performance.

Examples of meeting unique challenges include Ahtna’s work for the U.S. Army Corps of Engineers (USACE), Alaska District on Source and Incidental Contaminant CON/HTRW Remedial Action at Davis Air Force Base (AFB), Alaska. A fan marker (radio relay) station was constructed by the U.S. military on the western side of Adak Island during WWII. Station features included four former buildings, two generators, two aboveground storage tanks, a fuel pipeline, and a large radio antenna system. Operation of the station during WWII resulted in fuel spills and leaks, and over time lead-acid batteries and electronics have deteriorated and crumbled to the ground surface. Due to the extremely remote location of the station, heavy equipment, materials, and supplies needed for the project could only be transported by boat. Marine access was further constrained as the area was strongly influenced by winds and riptides, and only 30 feet of beach was considered usable (without any large rocks present). In addition, no roads were present and ground conditions would not support heavy equipment use of any type. With considerable support from USACE and input from U.S. Fish and Wildlife Service (USFWS), Ahtna successfully removed all contaminated debris from the site while preserving the area: 4,054 tons of petroleum-contaminated soil; 0.5 ton of broken lead acid battery debris and lead-shielded cable; 11 tons of lead-contaminated soil; 0.25 ton of electronics debris; 21.5 tons of cadmium contaminated soil; and two generators.

Additionally, Ahtna has been providing its expertise in remediating the challenges facing the nation with emerging contaminants, specifically per- and polyfluoroalkyl substances (PFAS). Work for the USACE Los Angeles and Sacramento districts includes remedial investigation (RI) at Davis Monthan AFB in Tucson, AZ; RI at Nellis AFB in Las Vegas, NV; RI at Creech AFB at Indian Springs, NV; RI at Morris Air National Guard Base in Tucson, AZ; Groundwater Treatment Systems and Landfills O&M Former Fort Ord (FFO), CA; and other PFAS-related work for the Air Force Civil Engineer Center (AFCEC), including PFAS Expanded Site Investigation at Plattsburg AFB, NY and a PFAS Water Treatability Study at Eielson AFB, AK. To date Ahtna’s PFAS projects total more than $72 million in contract value.

Ahtna is also well-positioned to support the growing future challenges of climate change and extreme weather impacts on sensitive habits and coastal areas with our environmental and marine services.
