DRAFT Chesapeake Bay TMDL

9-1 September 24, 2010

SECTION 9. CHESAPEAKE BAY TMDLS

This section presents, for both proposed amended WQS and current WQS, the Chesapeake Bay 

TMDL allocations for nitrogen, phosphorus, and sediment by Bay segment watershed that 

resulted from EPA’s evaluation of the jurisdictions’ draft Phase I WIPs as described in Section 8.

The MOS for nutrients is implicit for the nutrient allocations, having been built into the suite of 

decision-making tools and procedures and assumptions described in the previous chapters. In the 

case of the sediment allocations, the explicit MOS is built directly into the allocations themselves 

(see Section 6.2.3). Natural background loads are included in the LAs presented in this chapter 

and the referenced appendices.

9.1 Bay Segment Annual and Daily Allocations to Meet Proposed 

Amended WQS

Table 9-1, Table 9-2, and Table 9-3 provide the annual total nitrogen, total phosphorus, and 

sediment allocations to meet the proposed amended WQS for the watershed areas draining to 

each of the 92 Chesapeake Bay segments. Those allocations are calculated as delivered loads 

(the loading that actually reaches tidal waters) and as annual loads. These tables are structured by 

major basin from north to south with western shore first and eastern shore second. Then the Bay 

segments are in geographic order from the head of tide down river from north to south. Each of 

the 92 segments is displayed as white rows while contributing portions of some of the 92 

segments are displayed as gray rows. More detailed annual LAs by sector and annual WLAs by 

individual facility are provided in Appendix Q. Daily LAs and WLAs for the areas draining to 

the 92 segments are provided in Appendix R. Table 9-4 provides the individual WLAs for total 

nitrogen, total phosphorus, and sediment for each of the 483 significant permitted dischargers. 

All WLAs listed in Table 9-4 are calculated as edge-of-stream loads (the loading that reaches a 

simulated stream segment from a point in that stream’s watershed).

The WLAs and LAs were based in part on the allocations documented in the jurisdictions’ draft 

Phase I WIPs. Each draft Phase I WIP describes the methods and procedures the jurisdiction 

applied in developing WLAs and LAs for each of its respective areas draining to the 92 impaired 

segments of the Bay. As described in Section 8, EPA evaluated the jurisdictions’ draft Phase I 

WIPs and determined whether the jurisdictions met their jurisdiction-wide and basinwide target 

allocations for nitrogen, phosphorus, and sediment; and whether the jurisdictions provided 

sufficient reasonable assurance that nonpoint source reductions could be achieved and 

maintained through credible and “enforceable or otherwise binding” strategies. Where 

appropriate, EPA included backstop allocations to ensure that WQS would be met.

9.2 Bay Segment Annual and Daily Allocations to Meet Current WQS

Table 9-5, Table 9-6, and 

Table 9-7 provide the annual total nitrogen, total phosphorus, and sediment allocations to meet the current WQS for the watershed 

areas draining to each of the 92 Chesapeake Bay segments. The allocations are calculated as delivered loads (the loading that actually 

reaches tidal waters) and as annual loads. These tables are structured by major basin from north to south with western shore first and 

eastern shore second. Then the Bay segments are in geographic order from the head of tide down river from north to south. Each of the 

92 segments is displayed as white rows while contributing portions of some of the 92 segments are displayed as gray rows. More 

detailed annual LAs by sector and annual WLAs by individual facility are provided in Appendix Q. Daily LAs and WLAs for the 

areas draining to the 92 segments are provided in Appendix R.

Table 9-5, Table 9-6, and 

Table 9-7 provide the annual total nitrogen, total phosphorus, and sediment allocations to meet the current WQS for the watershed areas draining to each of the 92 

Chesapeake Bay segments. The allocations are calculated as delivered loads (the loading that actually reaches tidal waters) and as annual loads. These tables are 

structured by major basin from north to south with western shore first and eastern shore second. Then the Bay segments are in geographic order from the head of tide 

down river from north to south. Each of the 92 segments is displayed as white rows while contributing portions of some of the 92 segments are displayed as gray rows. 

More detailed annual LAs by sector and annual WLAs by individual facility are provided in Appendix Q. Daily LAs and WLAs for the areas draining to the 92 segments 

are provided in Appendix R.
