The European Directive 2002/49/EC on the assessment and management of environmental noise obliges European Union Member states to draw noise maps of communities with more than 100,000 inhabitants (agglomerations) and of areas near the major transport infrastructures for the assessment of noise outdoors. The Latvian law On Pollution and the Cabinet Regulation No 597 Procedures for Noise Assessment and Management (Adopted 13 July 2004) were harmonized with this European Directive to provide the legislative background for the local authorities to draw noise maps to be used as a basis for noise reduction plans. Riga Agglomeration strategic noise map was calculated using software IMMI 6.3. The map shows Riga City as rather noisy city because major roads and railway lines cross the city center and close to it. Riga Freeport, located on the banks of river Daugava, with its supply roads and branch-ways also add to contribute in the total noise levels. The European Directive 2002/49/EC on the assessment and management of environmental noise also obliges European Union Member states to draw Noise reduction Action plans. In Latvia, Capital Riga and Daugavpils are required to have the Action Plans. Action Plans must be completed by 18 July 2008. Much to our regret the Riga City noise reduction Action Plan is still under consideration and in process of development because it touches the interests of many parties.
