or 12 percent carbon dioxide.
(b) Any measurement to confirm compliance with the particulate concentration limit
shall occur when the tested boiler is operating at greater than 75 percent of the
maximum continuous rating. The method of sampling and analysis shall comply

caused by the discharges. The design of the odour diary programme shall be in
accordance with recognised good practice and shall be to the satisfaction of
