H.B. 1588 VETOES
plants and erosion and silt deposited in the rivers from construction and development
on land in the Watershed, the Patuxent River and Severn River are being polluted
and despoiled to a degree that fish, marine life, and recreational use of the rivers are
being adversely affected and curtailed.
(B) THE GENERAL ASSEMBLY FINDS THAT IN ORDER TO RESTORE WATER
QUALITY IN THE PATUXENT RIVER, THE STANDARDS OF THE 1981 PATUXENT
CHARETTE ACREEMENT, A CONSENSUS TO SUBSTANTIALLY REDUCE THE FLOW OF
PHOSPHORUS AND NITROGEN FROM SEWAGE WASTEWATER TREATMENT PLANTS TO
THE PATUXENT RIVER, MUST BE IMPLEMENTED AND ENFORCED WITHIN THE
PATUXENT RIVER WATERSHED.
[4-302.1.
(a) (1) Except as provided in paragraph (2) of this subsection, for purposes of
this section, concentrations and weights of phosphorus and nitrogen shall be
calculated on a monthly average basis.
(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:
(i) Phosphorus to a level of not more than 0.3 milligram per liter of
wastewater effluent; and
(ii) Nitrogen to a level of not more than 3.0 milligrams per liter of
wastewater effluent.
(c) On or before October 1, 1991, the Parkway Sewage Treatment Plant and
the Western Branch Sewage Treatment Plant shall remove nitrogen to a level of not
more than 3.0 milligrams per liter of wastewater effluent discharged into the
Patuxent River or any of its tributaries.
(d) On or before October 1, 1991, the Patuxent Plant in Anne Arundel County
and the Maryland City Plant shall:
(1) For that portion of wastewater flows in excess of the 1981 average
daily flow, remove nitrogen to a level of not more than 3.0 milligrams per liter of
wastewater effluent discharged into the Patuxent River or any of its tributaries; or
(2) Remove nitrogen from the total flow of wastewater effluent
discharged into the Patuxent River or any of its tributaries, if the resulting level of
nitrogen reduction is equivalent to nitrogen reduction achieved under item (1) of this
subsection.]
