Checklist and tips for reporting pollutant releases
Reporting online
complete comment boxes to give context to the information
keep contact information (especially email addresses) current
identify your Public Contact (the person whose name will appear on the website)
identify your Technical Contact
provide Coordinator information if you are reporting for multiple facilities
identify consultants in the Contractor Contact field
Common errors to avoid
Quantity errors
report quantities in correct units (e.g., grams vs. kilograms)
watch for decimal errors (e.g. 300 tonnes vs. 3.00 tonnes)
when using prepopulated forms, be sure to update quantities from previous years
Emission errors
the total of individually reported volatile organic compounds (VOCs) in Parts 1 and 2 should not be greater than the total VOCs reported in Part 4
if more than one tonne of a Part 5 Speciated VOC is released to air, report it both in your Part 4 total VOC calculation and individually under Part 5
total Particulate Matter (PM) should be ≥ PM10 which should be ≥ PM2.5
Reporting errors
calculate but do not report any manufacture, process or otherwise use (MPO) amounts. Report only the release, disposal and recycling amounts
lf you meet the MPO reporting threshold for a Part 1 substance, report all releases, disposals and transfers for recycling, even if the quantity eventually released is zero
do not report National Pollutant Release Inventory (NPRI) substances contained in final products shipped to customers or end users
to avoid double-counting, do not report disposals as both on-site and off-site
select “No significant change or no change” as the reason for changes in quantities reported from the previous year only if the change in quantities is less than 10%
Reporting checklist
Complete and keep documentation
assumptions and activity data
emission factors and estimation parameters
emissions measurement procedures, sampling procedures, equipment calibration and maintenance
internal calculations that support estimates
Other reporting checks
verify conversion factors
ensure that mitigation activities are considered in calculations
compare current year estimates with previous year’s emissions
