Pollution Prevention Planning Notices and Results

Pollution Prevention (P2) Planning Notices published in the Canada Gazette under Part 4 of the Canadian Environmental Protection Act, 1999 (CEPA 1999) require persons subject to the Notice to prepare and implement a pollution prevention plan in respect of a specified substance(s). Pollution prevention plan information is submitted to Environment Canada in Declarations of Preparation, Interim Progress Reports and Declarations of Implementation.

Measuring the overall progress and results that are achieved for an individual P2 Planning Notices is fundamental to evaluating the effectiveness of each Notice in meeting its intended objectives. A performance report is posted on the Notice's webpage following the reporting deadline.

Synthetic Rubber Manufacturing Sector – Isoprene
