The pollution inventory includes reporting on annual emissions of certain substances to air, controlled waters and land, and off-site transfers in wastewater and waste.
You must report to the pollution inventory if you:
operate under a Part A (1) Environmental Permit and have received a notice under Regulation 60 of the Environmental Permitting Regulations 2010
operate a sewage treatment works with a capacity at, or over, 100,000 population equivalents (PE)
dispose of radioactive waste to air, water or sewers covered by a permit issued under the Environmental Permitting Regulations 2010
run an opencast mine or quarry with a surface area over 25 hectares, or an underground mine and related operation (no capacity threshold)
Returns must be submitted by 28 February of each reporting year. You can use the Environment Agency’s online reporting system, or complete and return a paper reporting form.
Operators are no longer required to report resource efficiency data as part of their pollution inventory return. If you do submit data, it will not be used for any purpose.
For some sectors, there may be a specific benefit in continuing to collect resource efficiency information. Where this is the case, the Environment Agency will work with the relevant operators or trade associations to explore other options for collecting this data, for example through trade association corporate and social responsibility reporting schemes.
Pollution inventory: guidance notes
General and sector specific guidance on how to carry out pollution inventory reporting and the information you need to provide.
Use the Environment Agency’s online Pollution Inventory Electronic Data Capture (PIEDC) system to submit your data. The system will check your information for mistakes, automatically fill in standard fields and allow you to look at information you have provided in previous years.
The PIEDC online system opens for reporting on 1 January each year. The deadline for submitting your pollution inventory data is 28 February each year.
The PIEDC system opens in a pop-up window so make sure your pop-up blocker is switched off.
