The main sources of oil and oil product spills in Latvian marine waters

Aerial surveillance


Presently, it is not planned to procure and install sensor devices for aerial observation of the marine environment, which would provide effective 24-hour control, even during the dark when most of the oil and oil products are illegally released from ships. Aerial surveillance considerably promotes compliance with regulations for protection of environmental and biological resources. With sufficient financial resources, flights are made twice a week, and the number of recorded offences depends on the number of flight-hours.

The system of fines for oil and oil product spills, and environmental pollution, is fairly complicated. Captains committing pollution offences are fined 1000-5000 Ls, in accordance with the Administrative Offence Codex of the Republic of Latvia.

The Law On the Natural Resources Tax gives a tax rate of 8,000 Ls/t for lawful discharge (with the appropriate licence) of hazardous substance to water, but illegal discharges exceeding a concentration of 15 mg/l for oil and oil products are charged at twenty times the normal rate - 96,000 Ls/t.

The ship owner must compensate for the costs of oil and oil product clean-up.

The International Marine Organization and HELCOM are discussing the possible total banning of oil tankers with single-layer hulls to minimize accident risk of oil pollution.
