WHEREAS, The nutrient control policy under the Patuxent Charette
Agreement provided that all facilities discharging over 500,000 gallons a day of
wastewater must remove phosphorus to 1.0 mg/1 of wastewater and plan for a possible
0.3 mg/1 phosphorus limit; and
WHEREAS, The nutrient control policy under the Patuxent Charette
Agreement provided that all facilities plan for nitrogen removal to a limit of no more
than 3.0 mg/1; and
WHEREAS, After 25 years, several of the sewage treatment plants covered by
the policy are not meeting the standards envisioned by the Patuxent Charette
Agreement; and
WHEREAS, The living resources of the Patuxent River have yet to be restored
due in part to the failure to meet the standards of the Patuxent Charette Agreement;
and
WHEREAS, There is new technology, called "enhanced nutrient removal," that
can reduce phosphorus and nitrogen from sewage treatment plants to levels of 0.3
mg/1 of phosphorus and 3.0 mg/1 of nitrogen; and
WHEREAS, In 2004, the Bay Restoration Fund was created for the purpose of
paying the costs of upgrading sewage treatment plants in the State to achieve
"enhanced nutrient removal"; and
WHEREAS, The technology and funding now exist to make the restoration of
the Patuxent River a priority; now, therefore,
SECTION 1. BE IT ENACTED BY THE GENERAL ASSEMBLY OF
MARYLAND, That the Laws of Maryland read as follows:

(2) Nitrogen concentrations and weights shall be calculated only during
the period of April 1 through October 15 of each year and the nitrogen removal
requirements of this section are applicable only during this period.
(b) All sewage treatment plants discharging over 500,000 gallons of
wastewater daily into the Patuxent River or any of its tributaries shall:
(1) On or before January 1, 1989, remove phosphorus to a level of not
more than 1.0 milligram per liter of wastewater effluent; and
(2) On or before July 1, 1989, complete planning to anticipate the need
for the future addition of facilities to remove:
