EPA METHOD 9 (40 CFR 60 - Appendix A)
VISIBLE EMISSIONS OBSERVATION FORM
This is the form the EPA has on its website. Other forms may be required by state regulators within their state or for doing opacity observations at specific facilities. Review the facility permit or contact your state regulator to determine the proper form to use while conducting opacity observations. We have the most up-to-date field form available at every field exam.
