Environmental Quality Requirements Model Program Objective Memorandum Fiscal Years 2021–2025

Abstract: This document describes the methodology used to evaluate the costs incurred by organizations involved in planning, programming, budgeting, and execution of the Army’s environmental programs and estimating those costs for future year planning cycles, this model is referred to as the Environmental Quality Requirements Model (EQRM). The EQRM is used to develop the budget positions as presented to Congress to obtain the Operations and Maintenance appropriations. These appropriations fund the Environmental Quality Program which includes Compliance, Conservation and Pollution Prevention requirements. The model encompasses the commands under the funding structure of the Deputy Chief of Staff – G9 Installations which includes the following: Installation Management Command, the Army National Guard, the Army Reserve Command, and the Army Materiel Command.

Long-Term Stability and Efficacy of Historic Activated Carbon (AC) Deployments at Diverse Freshwater and Marine Remediation Sites

Abstract: A number of sites around the United States have used activated carbon (AC) amendments to remedy contaminated sediments. Variation in site-specific characteristics likely influences the long-term fate and efficacy of AC treatment. The long-term effectiveness of an AC amendment to sediment is largely unknown, as the field performance has not been monitored for more than three years. As a consequence, the focus of this research effort was to evaluate AC’s long-term (6–10 yr) performance. These assessments were performed at two pilot-scale demonstration sites, Grasse River, Massena, New York and Canal Creek, Aberdeen Proving Ground (APG), Aberdeen, Maryland, representing two distinct physical environments. Sediment core samples were collected after 6 and 10 years of remedy implementation at APG and Grasse River, respectively. Core samples were collected and sectioned to determine the current vertical distribution and persistence of AC in the field. The concentration profile of polychlorinated biphenyls (PCBs) in sediment pore water with depth was measured using passive sampling. Sediment samples from the untreated and AC-treated zones were also assessed for bioaccumulation in benthic organisms. The data collected enabled comparison of AC distribution, PCB concentrations, and bioaccumulation measured over the short- and long-term (months to years).

PUBLICATION NOTICE: Conspecific Attraction as a Management Tool for Endangered and At-Risk Species on Military Lands

Abstract: Movements of wildlife species and associated colonization of habitats is often unpredictable, potentially leading to ineffective management and/or interference with military training. Habitat restoration for wildlife management on military lands is a common, yet expensive, response to federal conservation and mitigation mandates, yet viable wildlife populations often fail to become established on restored habitat. Conspecific attraction, using the tendency for individuals of the same species to settle near one another, can be a cost-effective means of attracting animals to newly created or restored habitats. This work demonstrated the use of conspecific attraction as an alternative tool for encouraging colonization of restored habitats by at-risk birds and amphibians. Conspecific attraction was relatively straightforward to employ, but its effectiveness varied among species. We demonstrated clear success in attracting some bird (northern bobwhite; Colinus virginianus) and frog (wood frogs; Lithobates sylvaticus) species into our target areas but other species showed a neutral response. Conspecific attraction presents a cost-effective alternative to current management practices such as translocation or colonization after habitat is created or restored. Only minimal equipment costs (<$300/broad-cast station) and nominal work-hours are required to set up the equipment, and total cost was ~$1,200 per demonstration plot annually.
