# NASF

**- EPA Meeting:** 

**Mist Suppressants & Long Chain**

**PFC Issues**

April 15, 2010

Christian Richter, NASF

Jeff Hannapel , NASF

Washington, DC

# Industry

- EPA Discussion:

Goals & “Solutions Focus”

 Advance and broaden our dialogue with EPA / States / POTWs

 Provide additional technical information on LC PFC alternatives

 Discuss solutions re LC PFCs in surface finishing

 Accelerate transition to more sustainable alternatives

 Review benefits of industry

- EPA partnership

 Voluntary AND regulatory options

 Maintain industry compliance with strict standards

 Cr 6 MACT standard

 OSHA Cr 6 PEL standard

 Understand and recognize certain challenges

# Industry Overview

 Surface Finishing Industry (NAICS 332813)

 Electroplating, Plating, Polishing, Anodizing & Coloring

 ~ 2000 U.S. firms / chromium operations are subset

 Highly regulated

– across media programs

 Types of finishing operations

 Job Shops

– small businesses (80% < 75 employees)

 Captive Operations

– part of larger manufacturer

 Use of Long Chain PFCs in Surface Finishing

 Mist suppressants for Cr 6 metal plating and etching baths

 Success

– persistence in harsh chemical environment

 Industry Request for plating exemption in SNUR (2006

- 07)

 Managing technology transition to alternatives

# History: Uses of Long Chain PFCs

**Key factor: Beneficial role in minimizing Cr 6**  **releases**

 For chromium electroplating & related processes

 Ingredients in mist suppressants to achieve:

 Air emissions control

 Worker exposure control

 4 types of processes that have used LC PFCs

 Hard Chromium

 Decorative Chromium

 Chromic Acid Anodizing

 Chromic Acid Etch

 Range of manufacturing supply chains

– auto, aerospace

defense, electronics, industrial equipment

# Use Drivers: EPA & OSHA Regulations

**EPA Chromium NESHAP**

– Hard and Decorative Chromium

Electroplating and Chromium Anodizing Tanks (1995)

 Amended to allow compliance via fume suppressants ( 2004 )

**OSHA Chromium PEL**

– 53 ug /m 3 to 5 ug /m 3 ( 2006 )

 The new, much lower PEL is technologically feasible

because of effective mist suppressants

**California**

– **SCAQMD Rule 1469**

 Approved certain fume suppressants for use

 Allows companies to demonstrate compliance with federal

chromium NESHAP

# Options for Long Chain PFCs:

Elimination or Reduction

 

## Status of Alternative Mist Suppressant

**Chemistries**

 

## Industry Best Practices

# Status of LC PFC Alternatives:

Commercialization Has Advanced

# Recent Industry / EPA Action

 EPA Action on 2007 SNUR

 Plating Exemption w/monitoring of Minnesota

 Broader action

– European Union, Environment Canada

 NASF Engagement with EPA

 Industry Policy Forum

– status of alternatives (April 2008)

 Ongoing discussion, periodic updates on alternatives

 Minnesota Industry Data

– Brainerd

 “Controlled Experiment”

– model for predicting reductions

 EPA Region 5 Electroplating Study

 Chicago / Cleveland

– NASF outreach with industry

 Industry engagement with POTW community

– NACWA

# Industry “Partnership” Proposal

Pilot project

– develop a practical approach to addressing risk and

potential human exposure issues related to PFCs

 Project Goals

 Limit long

- chain PFC releases to the environment

 Promote greener alternatives to long

- chain PFCs

 Reduce concentrations of certain PFCs

 Compliance with the Cr 6 MACT standards

 Focus

 Multi

- media opportunity to address concurrent Air, Toxic

Chemical, Sludge/ Biosolids & Clean Water goals

 KEY EMERGING ISSUE

– POTW Biosolids Quality

# EPA PFC “Themes”

– Project Elements

 Air

- Specific Goals & Priorities

 Work with USEPA to get reasonable reduction/elimination of

long

- chain PFCs through the Cr 6 MACT RTR (August 2010)

 Water

- Specific Goals & Priorities

 Work with POTWs/MPCA/USEPA to accomplish water quality

protection and address biosolids concerns from POTWs

 Toxics

- Specific Goals & Priorities

 MNAMF / NASF will collaborate with local/state agencies to

develop a voluntary project for EPA’s Chemicals Action Plan

 USEPA Benefit

– By integrating water quality, air emissions and

P2 concerns with toxics/exposure prevention, NASF creates an

extremely high

- priority and key voluntary program for EPA

# NASF PROJECT:

Industry / EPA / State / POTWs

“Sustainable Technology Initiative”

3 Parts

(1) PROGRESS

– Finishing Industry efforts to date

(2) PARTICIPATION

– Expand industry involvement on substitutes

and best management practices for fume suppressants use

(3) PERFORMANCE

– Over some timeframe, how are we doing

on PFC reductions?
