Products 'requiring strong regulatory control,' as determined by the Oslo and Paris Commission (OSPAR). The list includes heavy metals such as zinc, lead and chromium. OSPAR, formerly known as PARCOM, is a group of experts who advise North Sea countries on environmental policy and legislation. The group has been influential in establishing North Sea legislation on drilling fluids that has served as the model for other operating areas. The Commission has published lists of environmentally acceptable and unacceptable products, referred to as the "green," "grey" and "black" lists.
