  • Nonylphenol and Its Derivatives
  • A Regulatory Update
  • Barbara Losey
  • May 23, 2003

Presentation Overview
  • Antitrust Reminder
  • European Union
  • Canada
  • United States
  • APERC Resources

3
  • European Union

4
European UnionNP/NPE
  • EU Risk Assessment on NP (April '01)
  • Exposure estimates were not based on monitoring
    data
  • Conservative assumptions used in calculations of
    risk
  • Precautionary Principle applied

5
EU Market Use Directive NP/NPE
  • Marketing Use Proposal 2002/0206 (August '02)
  • - Directive Proposal for 26th Amendment to
    Council Directive 76/769/EEC
  • Marketing and use of NP/NPE should be restricted
    to specific uses however, these specific
    permitted uses are not identified
  • Restricted uses are identified and refer to both
    NP and NPE

6
EU Market Use Directive Restricted Uses
NP/NPE
(1) Industrial and institutional cleaning
except controlled closed dry cleaning systems
where the washing liquid is recycled or
incinerated cleaning systems with special
treatment where the washing liquid is recycled
or incinerated (2) Domestic cleaning (3) Textiles
and leather processing except processing with
no release into wastewater systems with
special treatment where the process water is
pre- treated to remove the organic fraction
completely prior to biological waste water
treatment (degreasing of sheepskin)
7
EU Market Use Directive Restricted Uses
NP/NPE
  • (4) Emulsifier in agricultural teat dips
  • (5) Metalworking except
  • uses in controlled closed systems where the
    washing liquid is recycled or incinerated
  • (6) Manufacturing of pulp and paper
  • (7) Cosmetics including shampoos
  • (8) Other personal care products
  • except spermicides

8
Amendments to EU Market Use Directive NP/NPE
  • Reduce the concentration of NPE allowed in
    products affected by the use restriction from 1
    to 0.1 . The level of NP in products remains at
    0.1.
  • Restrict uses of NP/NPE, which result in
    discharges, emissions or losses to the
    environment
  • Request that the Commission consider establishing
    a concentration limit value for NP and NPE in
    sewage sludge that is to be spread on land

9
Amendments to EU Market Use Directive NP/NPE
  • Extend the list of affected uses to include
    co-formulants in pesticides and biocides
  • However, the restriction respects the validity
    of existing national authorizations of plant
    protection products or biocidal products
    containing NPE as a co-formulant, which have been
    granted before the entry into force of this
    Directive, until they expire

10
Amendments to EU Market Use Directive NP/NPE
  • Remove language, which allowed use of NPE when it
    is fully bound in the polymer matrix (finishing
    agents, textile printing, dyestuffs), water.
    Requires processing with no release into
    wastewater
  • Classify NP as a priority, hazardous substance
    and direct that the Commission shall submit
    proposals of controls for the cessation or
    phasing-out of discharges, emissions and losses
    of such substances under the Water Framework
    Directive

11
Timing of EU Market Use Directive NP/NPE
  • Agreement reached between the Parliament, Council
    and Commission (March 2003)
  • Legislation will most likely enter into force in
    the Member States by the end of 2004/beginning of
    2005
  • Member States are required to adopt and publish
    the laws, regulations and administrative
    provisions necessary to comply with this
    Directive no later than one year after the date
    of its entry into force. They must apply those
    provisions eighteen months after the entry into
    force.

12
TNPP
  • EU Assessment
  • TNPP Added to 4th Priority List
  • Rappateur is France
  • APERC is lead industry organization

13
TNPP
  • Current Activities
  • Submitted robust summaries to US HPV Program and
    to France
  • Responded to questions and issues raised by
    France
  • Limited success in gathering downstream
    use/exposure information
  • Undertook monitoring program with large customer
    in France which showed low-level release due to
    the very limited solubility of TNPP and its rapid
    hydrolysis, monitoring on NP was conducted

  • Canada

15
CEPA Risk Assessment Conclusion
  • Section 64(a)
  • NP and its ethoxylates from untreated or
    partially treated textile mills that discharge
    directly to the environment occur at levels that
    are likely to be causing harmful effects on
    aquatic organisms
  • Discharges from municipal wastewater treatment
    plants and pulp and paper mills contribute NP and
    NPEs to the environment at levels that are of
    concern at a limited number of sites

16
CEPA Environmental Objective
  • To achieve ambient concentrations in Canadian
    waters that do not exceed Canadian Environmental
    Quality Guidelines 1.0 ug/L NP TEQ for
    freshwater and 0.7 ug/L TEQ for marine water,
    such that no adverse effects are likely to occur
    in the resident aquatic biota

TEQ Toxic Equivalency Quotient, which
considers levels of NP, NPE, NPEC

CEPA Substance and Sector Risk Management
TME Textile Mill Effluents
18
CEPA Proposed Risk Management Goals
  • NP/NPE in Wet Textile Processing
  • Reduce use by 97 100 by 2009
  • Note Dry Textile processes such as nonwovens and
    permanent coating processes are not included
  • Pulp Paper
  • Voluntary use reduction (Target and Timeline TBD)
  • Municipal Wastewater Treatment
  • Address NP/NPE at product level

19
CEPA Proposed Risk Management Goals
  • NP/NPE containing products
  • Focus on soap, cleaning detergent products,
    textile and paper processing products
  • Reduce use by 50 (2 yr) and 100 (5 yr)
  • Proposed baseline year 1998 (or first year after
    1998 when records were kept)

20
CEPA Proposed Risk Management Instrument For
Products
  • Pollution Prevention (P2) Plans will be required
    by companies that
  • Produce or import products specifically for use
    in the soap and cleaning, textile, and pulp and
    paper industries and,
  • Exceed an annual threshold of 2000 kg of total
    NPEs used, based on concentrations in products
    and the annual amount of products produced or
    imported
  • P2 Plans will be posted on the internet

21
CEPA Risk Management Timeline
  • NP/NPE declared CEPA toxic (June 2001)
  • Started legislative timeline for risk management
  • Risk management process in progress
  • At least one risk management instrument to be
    recommended by June 2003
  • Textiles expected June 2003
  • Paper and Products expected Fall 2003
  • Risk management instrument to be finalized by
    December 2004

22
APERC Position on Proposed Risk Management
Strategy
  • Risk management objectives should be based on
    environmental EQGs
  • Environmental monitoring should be the primary
    measurement of risk management progress
  • Technical feasibility and economic impact of
    reformulation has been underestimated

23
APERC Position on Proposed Risk Management
Strategy
  • Substitution does not solve problems of poor
    practice and treatment
  • NPEs are already managed effectively in most
    situations
  • Environmental levels are generally only a problem
    in cases with inadequate treatment
  • Without adequate treatment all surfactants pose
    aquatic toxicity risk

24
APERC Position on Proposed Risk Management
Strategy
  • Pollution prevention plans should be flexible
    rather than prescribing use reduction mandates
  • APERC EMP Guidelines can be used in specific high
    volume industries (i.e. TME, Industrial
    Institutional Laundries)

25
NP/NPE As A Precedent
  • NP/NPE were declared CEPA Toxic primarily
    because they were found in WWT effluent and
    outfalls at levels of concern
  • These sites were generally associated with
    primary WWT or secondary WWT plants that were
    overloaded
  • Screening of Canadian DSL will likely result in
    additional down-the-drain chemicals to be
    declared CEPA Toxic because they are found in
    WWT effluent

26
Suggested Stakeholder Actions
  • Provide stakeholder comments when CEPA risk
    management recommendations are published in the
    Gazette
  • Wet Textile Processing (June 2003)
  • Products that Contain NP/NPE (Fall 2003)
  • Paper and Pulp (Fall 2003)

27
Canada NPRI
  • Addition of CAS RNs for NP, NPE to improve
    reporting accuracy
  • Addition of CAS RNs for OP, OPE to track
    substitution trends
  • Addition of CAS RNs for NPE derivatives such as
  • TNPP
  • Phosphate ester derivative of NPE
  • Ammonium salt of sulphated nonylphenol
    ethoxylate
  • NP-Barium salts

28
Canada NPRI
  • NP/NPE and NPE Derivatives grouped for threshold
    calculations and reporting purposes (Threshold
    10 tonnes)
  • OP/OPE grouped for threshold calculations and
    reporting purposes (Threshold 3 tonnes)

29
  • United States

30
United States
  • No regulatory restrictions on use (current or
    pending)
  • Broad approval for food contact applications for
    NPE and TNPP under FDA
  • NP/NPE were removed from the Washington State PBT
    program in 2002
  • Interagency Testing Committee dropped 27 APs from
    Priority Testing List, 3 remain

31
United States
  • EPA Risk Management Findings (NP)
  • No widespread risk to aquatic organisms in US
    waters
  • Wastewater treatment facilities are highly
    efficient in removing NP discharge

32
United States
  • EPA Water Quality Criteria (WQC) for NP
  • Uses a statistical analysis of the data
  • Initial draft WQC 5.8 µg/L
  • Revised draft WQC expected in 2003
  • EPA recalculating with more recent data
  • Revised WQC expected to be similar
  • With proper wastewater treatment and material
    handling, should not be a problem for most
    facilities

33
United States
  • EPA lead on OECD SIDS program for NPE
  • APERC is lead industry contact
  • Presented category justification and test plan to
    EPA on November 4, 2002
  • Generally well received
  • SIDS dossier will be posted on OECD web site for
    comment by other countries
