Visible Emissions Sample Clauses

Visible Emissions. Any emission containing particulate material that is visually detectable without the aid of instruments. This does not include condensed uncombined water vapor.

Visible Emissions. For any visible emissions observations conducted in accordance with EPA Method 22, the permittee shall record the information on the form referenced in EPA Method 22, Section 11.2. For any visible emissions observations conducted in accordance with EPA Method 22, record the information on the form referenced in EPA Method 22, Section 11.2. If the visible emissions observation was conducted only on the pilot flame, the record shall also include the reasons that the test could not be conducted during a blowdown event.

Visible Emissions. Annually, the pennittee shall conduct a visible em1ss10ns observation in accordance with the requirements at 40 CFR 60, Appendix A, Reference Method 22 to ce1iify compliance with the no visible emission requirement on the process flare. The observation period is 2 consecutive hours where visible emissions are not to exceed a total of 5 minutes during any 2 consecutive hours. At least once per year during a blow down event, the permittee shall conduct a visible emissions observation in accordance with the requirements at 40 CFR 60, Appendix A, Reference Method 22 to certify compliance with the no visible emission requirements. Each Method 22 test shall occur for the duration of the blow down event or for 30 minutes, whichever is less. Visible emissions shall not occur for more than 5 minutes during any consecutive 30-minute period. For blowdown events that occur for less than 30 minutes, visible emissions shall not occur for more the 15% during the duration of the blow down event. Alternatively, if the flare is located at an umnanned site, used only for emergencies, and where there are no scheduled blowdown-maintenance events to observe flare combustion, the pennittee shall at a minimum conduct the visible emissions observation in accordance with the requirements of EPA Method 22 on the pilot flame.

Each Method 22 test shall occur for the duration of the blow down event or for 30 minutes, whichever is less. Visible emissions shall not occur for more than 5 minutes during any consecutive 30-minute period. For blowdown events that occur for less than 30 minutes, visible emissions shall not occur for NSR Permit No. 7747-M5 Page A21 of A32 more the 15% during the duration of the blow down event. Alternatively, if the flare is located at an unmanned site, used only for emergencies, and where there are no scheduled blowdown-maintenance events to observe flare combustion, the permittee shall at a minimum conduct the visible emissions observation in accordance with the requirements of EPA Method 22 on the pilot flame.

Visible Emissions. If visible emissions from any process are significant, then the inspector should estimate such visible emissions by measuring the opacity by EPA Method 9 observation. Opacity should be documented formally, even if it means observing essentially zero opacity for six minutes. If a violation is observed a minimum of 30 minutes of readings should be recorded as this will greatly strengthen any enforcement action. The cause of these excess emissions should be investigated and reported (e.g., malfunctioning control equipment, upset, or other circumstances). When the opacity observations are made, a copy of the observation form should be provided to the facility representative. Appendix B presents a standard Visible Emission Observations (VEO) form that can be used for making Method 9 observations. A detailed description of Method 9 and the use of the VEO form is given in Section 3.12 of the EPA Quality Assurance Handbook for Air Pollution Measurement Systems. To make Method 9 observations valid, the inspector must be certified to conduct Method 9 observations, and the minimum data required by Method 9 must be obtained according to the conditions specified. If the items in the VEO form are correctly completed, then a valid, enforceable VEO will be the result.
