**Henderson, Nevada**
**INFORMATIONAL BRIEFING**
**Lieutenant Colonel Dan Rogers, AFMC LO/JAV**

## Overview

**Purpose**
**Historical Information and Events**
**IPSC Composition and Focus**
**Forum Composition and Focus**
**Where we are and Where we are going**

## Purpose of the Forum

**Gather together the leading experts currently working on the perchlorate issue**
**Provide the public with real-time information on perchlorate projects**
**Listen to public concerns**

## Historical Events and Chronology(before October 1996, I couldn’t spell perchlorate)

**What is Perchlorate?**
**Initial Objective!**
**27 Oct 96 Cleanup and Abatement Order**
**Method Detection Capability**
**TERA Peer Review**
**State Regulatory Partnering**
**20/21 May - Protocol Meeting and Funding**
**Inter Agency Perchlorate Steering Committee**

## What is Perchlorate?

**Primary Oxidizer in Solid Rockets**
**Titan, Minuteman, Peacekeeper, Hawk, Polaris, Space Shuttle **
**Army, Navy, Air Force, NASA**
**Neither Sinker Nor Floater**
**Very Stable in Water**

## Ammonium Perchlorate - A National Technical AssetIntegral to Strategic Defense and Space Systems

**Ammonium Perchlorate - A National Technical Asset****Integral to Strategic Defense and Space Systems**

**Notes:**
Ammonium perchlorate is the primary oxidizer in all solid propellants used in our strategic national defense systems; including inter-continental and submarine-launched ballistic missiles as well as delivery systems for NRO assets.
Ammonium perchlorate is a national technical asset.

## Initial Objectives

**Initial Objectives**

**Evaluate and Understand Potential Health Risks Associated with Perchlorate in the Environment**
**To Get the Best Scientific Information on the Toxicology of Perchlorate for Use by the Decision Makers and Most Importantly to the Public**
**Partner with All Stakeholders**
**DoD, Industry, Research & Regulatory Community**

## Integrated Approach

**Analytical**
**Health Effects**
**Treatment Technology**
**Ecological**

## October 96Central Valley Regional Water Quality Board

**Cleanup and Abatement Order**
**Emphasis on Observation of Plume Movement and Detection (MDL 400 ppb)**
**Time-line for Cleanup of Groundwater**
**Treatment Technology**
**Aerobic Pilot Project**
**Tyndall CRADA**

## Analytical Method Detection Limit(or how low can you go??)

**Pre Jan 97..................400 ppb (Aerojet)**
**January 97 ................100 ppb (Aerojet)**
**April 97 ....................... 4 ppb (DHS)**
**now replicated by ****CVRWQB****, Aerojet and others**
**Validation on both Aerojet and DHS Protocols by AF is Complete**
**1992/5 EPA “proposed” guidance level  (4-18 ppb) based on provisional RfD**

## March 97 Peer Review

**Convened by TERA, Sponsored by PSG**
**Overall Recommendations**
**Data insufficient**
**Solid base of studies needed**
**Minimum studies recommended**
**AF expertise recognized**
**Only “known” groundwater contamination site Sacramento **

## Post Peer Review Activities

**Seek study funding**
**Establish protocol review process**
**Texpert team integration (Who?)**
**Internal (DoD)**
**External (PSG, State and Federal Researchers and Regulators)**
**New source sites identified**

## Initial State Regulatory Partnering21 April 97 Meeting

**Management level action officers and technical support staff**
**California DHS, DTSC, CVRWQB, OHEHA, PSG**
**Partnership to serve the public**
**Best value for taxpayer dollars**
**Set meeting to decide best studies and protocol development**

## May 1997 Perchlorate Protocol Review Meeting

**20/21 May 1997 - Cincinnati**
**Expert**
**USAF (AL/HSC/BCA), PSG, DHS, DTSC, OEHHA, EPA Superfund Office, NCEA, Ohio State, U of Cincinnati, Cytec Industries**
**Goal?**
**Prioritized List of Reasonable Studies**
**Information Exchange**
**California Still the Only “Site”**

## Results

**Prioritized list of studies**
**Promise to assist in protocol development**
**Focus on the goal without regard to cost**
**Share final protocol information with the public**
**Begin studies as soon as possible**
**Partnering to secure needed funding**

## Inter Agency Perchlorate Steering Committee (13 Jan 98)

**Purpose**
**Sub Committees to address critical areas**
**Membership**
**Federal and State Governmental Agencies**
**Tribal Representatives**

## Forum Composition and Focus

**Bring together the experts in health effects/toxicology, ecological impacts/transport and transformation, analytical methods and treatment technology**
**Occurrence information**
**Provide information on current initiatives**
**Hear public and stakeholder concerns**

## Where We Are Today?

**Funded toxicology initiatives underway**

## Is There a Bottom Line?

**Goal - best scientific information to ensure protection of the nation’s drinking water supply**
**To get the best scientific information on the toxicology and occurrence of perchlorate to the decision makers and most importantly to the public**
**Maintain an integrated approach**
**Develop methods and technology as required**

## Bottom Line (continued)

**There are no limits to the success of this innovative project because of its talented and dedicated team (They don’t really care who gets the credit!)**
