Cabinet of Ministers Regulations No. 362 in Riga, 2 May 2006 (pr. No 25 32 §) rules on sewage sludge and compost use, monitoring and control, Issued in accordance with the law "on pollution" in article 11, the second paragraph of paragraph 11 i. General questions 1. determines the sewage sludge and compost use, monitoring and control. 2. Sewage sludge are colloidal sediment resulting from the processing of municipal, communal and industrial waste water treatment plants, as well as the sludge from septic tanks and other similar installations, waste water treatment. 3. Sewage sludge compost (compost) is the sewage sludge and various materials of plant origin (peat, leaf, straw, sawdust, and other pildmateriāl) breakdown products from the affected person an active aerobic microbiological activity. 4. Sewage sludge is broken down as follows: 4.1 treated sludge: sludge which have been the subject of at least one of the following treatments: 4.1.1 storage, also in liquid form, for at least 12 months (cold enzyme in capacity) without mixing and movement during storage;

Sewage sludge and compost quality, ensure: 5.1 sewage-sludge producers — the legal or natural person who manages wastewater treatment plant, which processes have technological sewage sludge;
5.2. the compost producer — the legal or natural person who use sewage sludge compost. 6. quality of sewage sludge sewage sludge shall be determined for each series (gutter water sludge mass with uniform chemical composition, similar to the physical and other characteristics), creating a single average sample in accordance with the provisions of annex 1. 7. the quality of the Compost is determined for each sequence of the compost (compost, made from sewage sludge and herbal pildmateriāl and composting at the beginning does not exceed 1000 tonnes). Compost for determining the quality of the series consists of the average sample that combines at least 25 individual samples. 8. Laboratory accredited by the national agency "Latvian National Accreditation Bureau" under the Latvian national standard LVS EN ISO/IEC 17025:2005 for testing and calibration laboratories "General requirements", or another Member State of the European Union notified body under the Ministry of Economic Affairs published a notice in the newspaper "journal", and which used this provision in annex 2 mentioned methods, sewage sludge or compost series medium sample States: 8.1 — heavy metals cadmium (Cd) , chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn), a mass concentration of dry matter;
