b.   Particulate matter emissions from each boiler shall not exceed 0.10 pound per million BTU. [20 DCMR 600.1]

c.   No visible emissions shall be emitted into the outdoor atmosphere from each boiler; except that no greater than 40% opacity (unaveraged) shall be permitted for two minutes per hour and for an aggregate of twelve minutes per 24-hour period during start-up, cleaning, soot blowing, adjustment of combustion controls, or malfunction.[20 DCMR 606.1]
