OSPAR CONVENTION FOR THE PROTECTION OF THE MARINE

ENVIRONMENT OF THE NORTH-EAST ATLANTIC

OSPAR List of Substances / Preparations Used and Discharged Offshore which

Are Considered to Pose Little or No Risk to the Environment (PLONOR)

(Reference number: 2004-10)1

2008 UPDATE

Criteria for inclusion of substances in the PLONOR list

Substances in the PLONOR list

1. The list at Appendix 1 contains substances whose use and discharge offshore is subject to expert

judgement by the competent national authority of Contracting Parties. These substances do not normally

need to be strongly regulated as, from assessment of their intrinsic properties, the OSPAR Commission

considers that they pose little or no risk to the environment.

Criteria for inclusion of substances in the PLONOR list

2. Requests to the Offshore Industry Committee for inclusion of new substances on this list should be

accompanied by the appropriate data required to undertake a prior assessment. The data required and the

acceptance criteria axe the following:

Categories Minimum data required for Acceptance criteria

assessment

All substances, including

inorganic salts (naturally

occurring or constituents of

seawater) 2, and

other natural organic

substances, non-water

soluble (e. g. nutshells, fibres

etc.)

Parts 1 and 3 of HOCNF shall

be completed,

supported by the Safety Data

Sheets if necessary

CAS-number(s) shall be

provided if they exist

Classification with risk phrases

according to Council Directive

67/548/EEC, Annex VI does not

lead to any of the following risk

phrases: R50, R50/53, R51,

R51/53, 52, R52/53, R533.

The substance is not

Carcinogenic (cat 1 & 2)4,

Mutagenic (cat 1 & 2) or Toxic

for Reproduction (Cat 1, 2 &3)

Source: OSPAR 2004 Summary Record - OSPAR 04/23/1, Annex 9;

Revisions to the List were made in January 2005 following a written procedure to add CAS numbers and names;

OIC 2005 amended the List by adding new substances and CAS numbers - OIC 2005 Summary Record 05/15/1,

Annex 6. OIC 2006 revised the criteria, see OIC 06/13/1, Annex 5. OIC 2007 agreed to add calcium ammonium

nitrate to the list. OIC 2008 agreed on additions and changes, see OIC 2008 Summary Record paragraph 3.38

Does not include salts of heavy metals.

For Substances classified by R50, R50/53, R51, R51/53, R52, R52/53, R53 exceptions can be made from these

criteria, providing the properties of the substances are different in seawater (e.g. pH effects of acids, bases, salts).

Exception must be made for exposure routes not relevant to the marine environment, e.g. R49 May cause cancer

by inhalation.

existing substances on the list, or for removing substances from the list.

3. Any supplier, vendor or organisation wishing to put forward a new candidate substance for inclusion

in the PLONOR List, or to add additional CAS numbers to substances already on the PLONOR List, should

submit a request to a sponsor Contracting Party. The data6 for new substances should be submitted in

accordance with the criteria above.

4. The sponsor Contracting Party should review the data to ensure that the criteria are met and that they

are satisfied with the data presented. If the sponsor Contracting Party considers that the request should be

approved, that Contracting Party should then circulate the data, preferably in electronic form, to the List of

National Contact Points Concerning Chemicals used Offshore (see the appropriate Annex of the most recent

OIC Summary Record) at least 20 weeks before the annual meeting of the Offshore Industry Committee,

with a recommendation for inclusion of substances in the PLONOR list or the inclusion of additional CAS

numbers for substance already on the list.

Information on oxygen depletion, eutrophication, physical effects etc has been deleted as a criterion since these

effects are dealt with as part of risk assessments.

Data presented in the HOCNF does not have to have any particular vendor details or tonnage to be used, as

PLONOR list items may be supplied by a number of vendors etc. Supplier details and tonnage to be used would

have to be provided and considered at the time of use when applying for a permit under national regulations for

the implementation of the Haxmonised Mandatory Control System under OSPAR Decision 2000/2. However, the

sponsor Contracting Party may provide an indication of current tonnage used in their own area, if this

information is readily to hand.

5. The national contact points under the lead of the sponsor Contracting Party should work in accordance

with the working procedures for intersessional correspondence groups as described in the current version of

the Rules of Procedure of the OSPAR Commission. Following receipt of any comments from the national

contact points, within the specified deadlines, the sponsor Contracting Party should prepare a final proposal

for consideration at the annual meeting of the Offshore Committee. The proposal should be submitted by the

sponsor Contracting Party at least six weeks before the annual meeting and should contain a short description

of comments or objections raised by Contracting Parties and the way in which the sponsor Contracting Party

has taken these comments or objections into account in their final proposal to OIC.

6. Requests to remove substances from the PLONOR list can only be generated by Contracting Parties,

and must be the subject of a proposal for consideration at the annual meeting of the Offshore Industry

Committee. The proposal should be submitted by the relevant Contracting Party at least six weeks before the

annual meeting and must contain a reasoned cause of concern related to the criteria mentioned in paragraph 2

above. Such requests should also be accompanied by the data required for assessment by OIC.

7. Adoption of any proposal submitted to OIC will require the unanimous approval of the Contracting

Parties represented at OIC.
