Introduction
A computerized data base of Chesapeake Bay point source dischargers has been developed to
document information on point source pollutant input to the Bay. Installed on the Chesapeake
Bay Program computer and available to registered users, the Chesapeake Bay point source data
base (Atlas 85) provides a central repository for locational and administrative data on almost
6,000 point source dischargers located in the commonwealths of Virginia and Pennsylvania, the
states of Maryland, New York, West Virginia and Delaware, and the District of Columbia.
Point sources of pollution are defined as municipal and industrial plants that discharge waste to
a water body from a discrete pipe or ditch. Municipal point sources are wastewater treatment
plants that receive and treat both dome0'; wastewater and wastewater generated by local
commercial and industrial activities. These wastewaters contain large amounts of organic
matter, including nutrients such as phosphorus and nitrogen, that i lay cause significant
depletion of dissolved oxygen (DO) in die receiving stream. Heav\ metals, chlorinated
hydrocarbons and other toxic substances may also be present.
Industrial point sources are commercial and industrial plants that carry out diverse and complex
manufacturing processes which require solvents, catalysts, and other chemicals that contaminate
discharged wastewater. These wastewaters may also contain large amounts of oxygen
demanding substances. In the Bay watershed, there are 461 different types of industrial
activity, including coal mining, iron and steel production, electric power generation, seafood
processing, inorganic and organic chemical manufacturing, concrete manufacturing, and
petroleum refining.
The point source data base contains information on 1345 municipal dischargers and 4651
industrial dischargers. Of these, 205 municipal and 192 industrial dischargers have been
designated as major dischargers. The location and distribution of major dischargers are
displayed in Figure 1. It is important to note that this point source map shows only the general
location of sources and is intended primarily to illustrate the number and geographic distribution
of selected categories of point sources.
The point source data base provides 1985 wastewater characteristics for more than 500
municipal dischargers and estimates nutrient and toxicant wastewater concentrations for 93
different types of industrial activities with the potential to generate and discharge these
pollutants.
The information in the point source data base was initially compiled from federal data bases
such as the Environmental Protection Agency (EPA) Needs Survey and Permit Compliance
System; it was then refined and expanded with state and facility data. A more complete
description of data sources may be found in the data base documentation file available from the
Chesapeake Bay Liaison Office.
All effluent data are annual averages for the calendar year 1985. As such, the information in the
data base serves as the baseline from which progress towards meeting the Bay Agreement
commitment to reduce nutrient loads, reduce toxic discharges and control conventional
pollutants can be measured. Importantly, municipal wastewater characteristics and industrial
nutrient loads are consistent with state estimates presented in state nutrient reduction strategies
(April 1988). These estimates include industrial nutrient sources not available during
preparation of the report, "A Commitment Renewed" (Implementation Committee, February
1 3
-------
1988). As a result, industrial nutrient loads (and percentages of point source total) are slightly
higher than those cited in the earlier report.
Other applications of the data base include evaluation of point source management alternatives,
tracking program implementation, model input and loading calculations. Descriptive statistics
and analyses derived from the data base are presented in the following discussions. The final
section contains a data dictionary and describes how the data base may be accessed and used for
other analyses.
The point source loadings presented are discharged pollutant loads. Discharged pollutant loads
are "end of pipe" loads and do not reflect natural physical and chemical decay processes that
occur as the loads are transported from the upper watershed to the Chesapeake Bay. The fall
line (defined as the point on the Bay tributaries, usually marked by a waterfall, which signalizes
the boundary between the resistant crysalline rocks of the Piedmont Plateau and the less
resistant sediments of the Atlantic Coastal Plain) creates a natural divide to characterize nutrient
input to the Bay basin. Above the fall line (AFL) pollutant loads are greatly influenced by decay
processes, dependent upon their distance from the Bay; below the fall line (BFL) pollutant loads
are not generally considered to be reduced by these processes because of their proximity to the
Bay. The fall line and the eight major drainage basins in the Chesapeake Bay watershed are
illustrated in Figure 2. Loads are calculated in million of pounds per year from flow and
effluent concentration data contained in the point source data base. Nutrient and conventional
pollutants information is presented, followed by information on toxic pollutants.

The Pollutants: Nutrients
Municipal facilities are the major point source of nutrients to the Bay, discharging 94.0
percent of the total phosphorus and 88.3 percent of the total nitrogen loads (Table 1).
Municipal and industrial nutrient loads presented in Table 1 are illustrated in Figures 3 and
4. The table and figures show that municipal sources BFL are the major source of
nitrogen; municipal sources AFL are the major source of phosphorus. Table 1 shows that
these sources discharge 59.6 percent of the nitrogen and 52.0 percent of the phosphorus
loads respectively.

MUNICIPAL NUTRIENTS
Municipal flows and nutrient loads are presented by basin in Table 2. Flows and nutrient loads
for the four largest basins are illustrated in Figure 5. The largest municipal flows are discharged
within the Potomac (521.3 million gallons/day (mgd)) and Susquehanna (336.2 mgd) basins.
The largest nitrogen loads are also discharged within the Potomac (24.4 million pounds/year)
and Susquehanna (18.6 million pounds/year) basins. The largest phosphorus loads are
discharged within the Susquehanna (5.0 million pounds/year) and James (3.6 million
pounds/year) basins.

Maryland, Pennsylvania, Virginia and the District of Columbia have developed and imple-
mented regional policies to control phosphorus. Only Maryland's Nutrient Control Strategy for
the Patuxent River basin requires nitrogen control at selected dischargers, but, the strategy had
not yet been implemented in 1985. Phosphorus control policies affect dischargers in the lower
Susquehanna, West Chesapeake, Patuxent and upper Potomac river basins. Locations of
dischargers subject to the policies are shown in Figure 6. Specific facilities subject to nutrient

control policies, policy requirements, and 1985 operational data are listed in Table 3. Figure 7
summarizes basin level data and shows, basin-wide, the phosphorus controlled plants account
for 57 percent of the total flow, and 53 percent of the total nitrogen, but only 22 percent of the
total phosphorus load. A more complete description of the regional nutrient control policies may
be found in Chapter 3 of the report "A Commitment Renewed."
Flow-weighted mean nutrient concentrations from municipal discharges are shown in Table 4.
Mean nitrogen concentrations range from 15.6 to 24.0 mg/1. Phosphorus concentrations range
from 1.1 to 6.7 mg/1 with the lowest mean effluent concentration occurring in the Potomac
River. The Potomac has the largest flow subject to a phosphorus policy (440 mgd) and the
most stringent phosphorus discharge limits (0.18 mg/1).
Facilities with operational flows less than 0.5 mgd account for 83 percent of the total number of
municipal plants. However, they account for only a little more than 3 percent of the total flow,
3 percent of the total nitrogen load and about 7 percent of the total phosphorus load discharged
by municipal plants (Tables 5 and 6). Because of the large number of these plants and the small
percentage of the nutrient load they contribute, most data gathering and analysis focuses on
discharges with flows greater than 0.5 mgd.
The distinction between municipal loads discharged AFL and BFL is important because AFL
loads are likely to be decreased by physical and chemical processes as they are transported to
the Bay. As stated earlier, however, this discussion deals with discharged loads and does
not account for decay processes which are difficult to quantify. Quantification of the decay
processes is the domain of the watershed model. Municipal loadings AFL and BFL for each
basin are presented in Tables 7 and 8. Municipal flow discharged AFL and BFL is illustrated

municipal flow and nitrogen loads from AFL and BFL. The nitrogen load is directly
proportional to the volume of wastewater discharged. Figure 10 shows municipal flow and
phosphorus loads from AFL and BFL. The phosphorus load is not proportional to the flow
as was the nitrogen load providing further evidence of the impact of phosphorus control
policies.

In the 1987 Chesapeake Bay Agreement, Maryland, Pennsylvania, Virginia and the District of
Columbia agreed to the reduction of nutrient loads and control of conventional pollutant loads.
Each state's municipal flow and discharged pollutant loads are presented in Table 9 and
illustrated in Figure 10.
The largest flow and nutrient loads are discharged in Virginia. Maryland discharges the
second highest volume of wastewater and pounds of nitrogen. Pennsylvania discharges
the second highest phosphorus load. The most striking feature of Figure 11 is the large
flow discharged by the District of Columbia and the very small phosphorus load, which is
achieved through the use of the most advanced treatment technology available.
The District of Columbia's Blue Plains sewage treatment plant is a large regional plant
serving the Washington Metropolitan area and adjacent high density residential areas in

Maryland and Virginia. These areas contribute 46 percent (138 mgd) of the total flow (309
mgd) at Blue Plains. Under a regional policy that provides for financial participation as
well as compatible treatment in nearby plants, these areas contribute financially to the
operation of Blue Plains.
Each state's municipal flow and pollutant loads discharged AFL and BFL are presented in
Tables 10 and 11. The flow and loads from the District of Columbia include its
contribution as well as both Maryland and Virginia's contribution to Blue Plains.
Municipal wastewater treatment plants in Pennsylvania are the major source of nutrients
discharged AFL and municipal wastewater treatment plants in Virginia are the major
source BFL.
Table 12 presents design flow capacity and estimates of year 2000 flows by Maryland,
Virginia and the District of Columbia. In any event, the incremental nutrient load increases
ccurring between 1985 and 2000 must be controlled to meet Bay Agreement
commitments. Higher projected flows provide a safety margin in calculating needed
reductions.
INDUSTRIAL NUTRIENTS
Categories of dischargers with the potential to discharge industrial nutrients and estimated
concentrations are listed in Table 13. Developed by the EPA Effluent Guidelines Division,
these default values can be used to target categories of dischargers as potential sources of
nutrients. Effluent monitoring, however, is required to quantify loadings. Estimates of
industrial nutrient loads discharged by basin AFL and BFL are presented in Table 14.

The Pollutants: Toxicants
MUNICIPAL TOXICANTS
Municipal point sources may discharge toxic substances received from industrial sources or
produced by in-plant treatment during chlorine disinfection or decomposition of
nitrogenous organic matter. Many industries use local municipal facilities to process their
wastes instead of having their own treatment facilities. Industrial wastes, however, often
contain heavy metals and toxic substances that are incompatible with normal sewage
treatment processes and may interfere with treatment operations, pass through untreated, or
contaminate sludge. Consequently, municipal plants that treat significant amounts of
industrial wastewater or are larger than 5.0 mgd, are required to implement pretreatment
programs.
There are 105 facilities identified in the point source data base n quired to develop and
implement pretreatment programs. Listed in Table 15, their pretreatment programs have been
approved by EPA or the delegated state and the municipalities are currently in the process of
implementing these plans. Figure 12 shows the location of municipal plants with pretreatment
programs. Other information provided in Table 15 includes design flows, industrial input
flows, BOD 5 and TSS effluent concentrations.
Municipal plants may produce chlorinated hydrocarbons during chlorine disinfection. Discharge
of these and other chlorinated by-products are extremely toxic to aquatic life. Both Virginia and
Maryland have undertaken significant efforts to control chlorine toxicity. Virginia has
established a chlorine water quality standard based on EPA water quality criteria that requires
strict control or total elimination of chlorine from discharged effluent. This standard is being
applied to municipal dischargers to determine permit limits as NPDES permits are reissued or
reopened.
In Maryland, state water quality standards prohibit the use of chlorine or chlorine compounds in
the treatment of wastewaters discharged to waters classified as natural trout waters and require
dechlorination for wastewaters discharged to waters classified as shellfish harvesting. Table 16
lists Virginia and Maryland municipal dischargers, 1985 chlorine concentrations and status of
current (1988) chlorine control. Only Maryland dischargers currently not providing chlorine
control are listed.
Ammonia is another toxic substance discharged by municipal plants. It is produced during the
decomposition of nitrogenous organic matter in the treatment process and may have a toxic
effect on aquatic life depending upon the pH, dissolved oxygen level and total ammonia
concentration of the receiving water. Municipal dischargers with ammonia or total Kjeldahl
nitrogen (TKN) limits are listed in Table 17. Some dischargers such as Back River, Western
Branch and Parkway do not currently meet these limits but are planning upgrades to provide the
required nitrogen control that will be critical in the states' plans to meet nutrient loads
reductions.
An effective means of evaluating the toxic potential of discharged effluent is through bio-
monitoring. Biomonitoring is the measurement of the acute and chronic toxic effects of
discharges on living organisms in a controlled experiment. When toxicity is confirmed, the
discharger may be required to conduct a toxicity reduction evaluation (TRE). The overall
objective of the TRE is to identify the source(s) of toxicity and develop acceptable control

are underway or planned are identified in Table 18. The distribution of these facilities is shown
in Figure 13. The point source data base is currently the only system available to record and
track these data. Table 19 provides additional information on the TRE status of municipal

INDUSTRIAL TOXICANTS
Industrial manufacturing is a complex process that requires the use of many raw materials,
catalysts, solvents and other chemicals that are extremely hazardous. Process or cooling
wastewater contaminated by these substances may be toxic unless properly treated. Indus-
trial categories with the potential to discharge heavy metals and/or priority pollutants are
identified in Table 20. These values are default values developed by the EPA Effluent
Guidelines Division and can be used to target categories of industrial dischargers as poten-
tial sources of toxicants. Effluent monitoring, however, is required to quantify loadings.
Industrial dischargers may also be required to biomonitor their effluent if toxicity is suspected.
Industrial dischargers with biomonitoring or TRE requirements are listed in Table 21. Their
locations are shown in Figure 14. Table 22 provides additional information on the TRE status
industrial dischargers in Maryland and Virginia.
Federal Dischargers
The Chesapeake Bay Agreement specifically calls for the control and reduction of pollutant
loads from federal facilities. The point source data base contains an inventory of 181
wastewater treatment facilities owned by the federal government. This inventory is being used
to track progress in meeting this Bay Agreement commitment. Major federal facilities and their
pollutant loads are presented in Table 23.
