The Chesapeake Bay numerical chlorophyll a criteria and reference concentrations were derived to address specific water quality, human and aquatic life impairments when applied in specific seasons and to specific salinity-based tidal habitats. EPA strongly encourages the states to adopt the harmful algal bloom-based numerical chlorophyll a criteria for tidal fresh and oligohaline tidal waters where algal-related impairments are expected to persist even after attainment of the Chesapeake Bay dissolved oxygen and water clarity criteria. This is an addendum to the original report.
