Best Management Practices or BMPs: In this report, forestry practices specified in state-level forest management guidelines or legislation.BMPs encompass the practices required by the mandatory forest practice acts in some states as well as the voluntary or quasi-regulatory BMP programs in other states.Most often used in even-aged silvicultural systems.
Bleached chemi-thermomechanical pulp: A stronger and brighter variation of chemi-thermomechanical pulp (TMP), a pulp that reduces energy consumption for certain paper grades by combining thermal pretreatment with chemical methods.
Bleaching: Chemical treatment of pulp fibers for the purpose of: (1) increasing pulp brightness, (2) improving cleanliness by disintegrating contaminating particles such as bark, and (3) improving brightness stability by reducing the tendency of bleached pulp to turn yellow. Brightness: Light-reflecting property of paper or pulp.
Coastal Zone Management Act: Federal statute that requires states to formulate programs to reduce water pollution from nonpoint sources impacting coastal waters, including forestry activities. Color: Used to describe colored wastewater discharge from chemical pulping, pulp bleaching or colored-paper manufacture.
State management measures can include land use management restrictions and control measures similar to the Best Management Practices developed under the authority of the Clean Water Act. The wastewater is colored by the lignin and lignin derivatives present in spent cooking liquors.

The BOD in a test bottle can consume oxygen well in excess of 100 days, and the five-day test may capture only 50-75% of the total BOD.
(2) Papermaking chemical commonly used for precipitating rosin sizing onto pulp fibers to impart water-resistant properties to the paper.
Artificial regeneration: Method for producing a new stand of trees following harvesting, in which tree seedlings (or more rarely, seeds) are planted.
The major force behind the conversion from acid to alkaline papermaking is the greater strength of the alkaline sheet, which permits higher levels of clay and calcium carbonate filler.
Additionally, maintenance costs for alkaline papermaking are less because such systems are less prone to corrosion, and are more easily closed than acid systems. (1) Chemical release agent, used when pure fiber furnish is run at low basis weight to prevent sticking to the paper machine presses.
