events at City facilities [two (2) persons per event] each event anticipated to
be four (4) hours or less in duration at City facilities. Depending on sampling
plan agreed upon with City, some events may be on same days; some may be
at night or on weekends.
bo
It is anticipated that consultant personnel will measure ambient hydrogen
sulfide at fifteen (15) locations during each event; ammonia, methyl
mercaptans, ethyl mercaptans, and/or amines (using Draeger tubes) at up to
six (6) locations on each visit; and record observations of operational events
and atmospheric conditions. On four (4) Consultant site visits, samples will
be collected for analysis by an independent laboratory for testing for an array
of potential odorants. A total of up to sixteen (16) bag samples will be
collected and tested.
City personnel will record and provide wind direction and speed information
during each sampling event (whether by City or Consultant personnel), and
will conduct odor observations at times agreed to in the sampling plan.
Consultant will provide instruction and data recording forms for use by City
personnel.
It is anticipated that field-testing will proceed for a twelve (12)-week
