Added footnote 5 to indicate grab samples to be taken if compositor is out of service. Also, corrected kilometer distance on BD-10. Miles to kilometer conversion had been in error.
11-7 Corrected kilometer distance on BD-10. Miles to kilometer conversion had been in error.
11-8 Expanded the number of required sample locations from two to four. Changed frequency for food products from three times a year to annually. Revised to annually due to short growing season and annual harvest associated with the area.

Revised requirement for charcoal cartridge collection and analysis to biweekly. A longer collection time j makes it easier to meet required LLD's.
