HELCOM RECOMMENDATION 13/7

Adopted 6 February 1992, having regard to Article 13, Paragraph b) of the Helsinki Convention

REDUCTION OF AMMONIA VOLATILIZATION FROM STORAGES

THE COMMISSION,

RECALLING Paragraph 1 of Article 6 of the Convention on the Protection of the Marine Environment of the Baltic Sea Area, 1974 (Helsinki Convention), in which the Contracting Parties undertake to take all appropriate measures to control and minimize land-based pollution of the marine  environment of the Baltic Sea Area,

HAVING REGARD also to Article 3 of the Helsinki Convention, in which the Contracting Parties shall individually or jointly take all appropriate legislative, administrative or other relevant measures to prevent and abate pollution,

RECALLING FURTHER the Ministerial Declaration of 1988 and the Baltic Sea Declaration of 1990, calling, inter alia, for a substantive reduction of the inputs caused by diffuse sources,

RECOGNIZING  the fact that a substantial part of the eutrophi­cation problems observed in the Baltic Sea Area is caused by nutrient inputs from diffuse sources,

DESIRING to limit this pollution,

 

RECOMMENDS to the Governments of the Contracting Parties that:

 

a)      storage capacity of farms having more than 5 animal units according to Appendix must be sufficient to allow application of manure on appropriate periods for minimizing volatilization;

 

b)      slurry storages should be covered, inter alia, with floating coverages, membrane covers, solid lids or mem­branes, possibly in conjunction with retrieval of methane gas. Loading of storages under the slurry surface should be promoted;

 

c)      urine storages should be covered in a way that prevents ammonia to volatilize from the storage;

 

d)      programmes should be developed and action taken to implement the above mentioned measures and to report on the effect of these measures or any other measures taken to reduce ammonia volatilization from storages,

 

RECOMMENDS ALSO that the actions stated in a) - d) should be implemented by the Contracting Parties within 5 years,

 

RECOMMENDS FURTHER that the actions taken by the Contracting Parties, e.g. economic incentives, recommendations, regulations, agricultural advice, should be reported to the Commission in 1994 and thereafter every three years.
