H

HAZARD RANKING SYSTEM (HRS). A scoring system used to evaluate potential relative risks to public health and the environment from releases or threatened releases of hazardous substances. The EPA used the HRS to calculate a site score for NAF Adak. The HRS is based on the ability of actual or potential releases of hazardous substances from a site through air, surface water or groundwater to affect people. This score was the primary factor used to decide whether NAF Adak should be placed on the National Priorities List.

HAZARDOUS SUBSTANCE. Any material or waste that poses a threat to public health or the environment. Typical hazardous substances are materials that are toxic, corrosive, ignitable, explosive or chemically reactive.

INSTALLATION RESTORATION (IR) PROGRAM. Program implemented under the Defense Environmental Restoration Program (DERP) to investigate and remediate DoD installations. The IR Program conforms with the NCP and CERCLA and applies guidelines promulgated by the EPA. The IR Program for active installations is funded by the Environmental Restoration, Navy account; the IR Program for BRAC installations is funded through the Military Construction Act.

INTERIM REMEDIAL ACTION (IRA). IRAs are all discrete actions implemented under remedial authority that are taken to prevent or minimize the actual/potential release of hazardous substances, pollutants or contaminants so that they do not endanger human health or the environment. The purpose of an IRA at ADAK is to achieve early action using remedial authority at those sites that meet the general principles for an IRA discussed in the National OHSs Pollution Contingency Plan (Preamble to 40 CFR 300.430(a)(1), 55 Fed. Reg. 8703-8706; March 8, 1990). IRA decisions are intended for straightforward sites that are limited in scope.
