Massachusetts Department of Environmental Protection MMaassssaacchhuusseettttss EEssttuuaarriieess PPrroojjeecctt Year 2 QAPP Revisions (Round 3 Embayment Prioritization) April 2004 QAPP Revisions Round 3 Embayment Prioritization Overview: The Massachusetts Estuaries Project is tasked with updating its QAPP to include the additional embayments selected in the annual prioritization process. The following update of the Year One Final Massachusetts Estuaries Project Quality Assurance Project Plan (QAPP) dated June 13, 2003 and approved in July of 2003 focuses on the integration of a third round of embayment prioritization. The round three embayment prioritization builds on the QAPP for embayments 1 – 20, summer 2002 field season, and the round two prioritization embayments 21 – 34, summer 2003 field season. The Massachusetts Estuaries Project (MEP) Year One Final QAPP has not undergone any revisions relative to the methodology employed to conduct the nutrient analyses in each embayment system, nor has it changed relative to the process utilized for conducting the hydrodynamic and water quality modeling. As such, details regarding: • A Project Management • B.1 Review of Nitrogen Related Water Quality Monitoring Data • B.2 Hydrodynamic Modeling • B.3 Watershed Nitrogen Loading • B.4 Nitrogen Regeneration Within Embayments • B.5 Linked Watershed-Embayment Nitrogen Model • B.6 Habitat Assessment • B.7 Synthesis of Modeling and Habitat Assessments • C Assessment and Oversight • D Data Validation and Usability remain unchanged relative to what was previously submitted in the Final QAPP dated June 13, 2003, except for two changes in Project Management and one change in Section B.6 relative to dissolved oxygen (D.O) mooring deployments. The specific changes are as follows: (1) Section A (Project Management) Bruce Rosinoff, presented in the Year One Final QAPP as EPA Project Officer responsible for aspects of policy and coordination related to the Project has been replaced by Mary Jo Feuerbach, Bruce Rosinoff’s replacement at US EPA Region 1. Therefore, the distribution list presented on page 5 of the Year One Final QAPP is hereby amended to read: 2 Name (#copies) Address Coastal Systems Program School of Marine Science & Technology (6 Copies) University of Massachusetts-Dartmouth 706 Rodney French Blvd. New Bedford, MA 02744 508-910-6316 Department of Environmental Protection Brian Dudley (1 Copy) DEP-SERO 20 Riverside Drive Lakeville, MA 02347 508-946-2753 Department of Environmental Protection Art Screpetis, MA DEP / DWM (1 Copy) 627 Main Street, 2nd Floor Worcester, MA 01608 508-767-2875 Environmental Protection Agency Mary Jo Feurbach (1 Copy) USEPA Region 1 One Congress Street Boston, MA 02203 617-918-1578 Environmental Protection Agency Arthur E.

The position that was previously filled by Mr. Rapacz has in part been filed by Bruce Rosinoff who is currently under contract to the MEP on a part time basis. An additional hire is currently underway to assume some of the project responsibilities previously held by Mr. Rapacz. Therefore, the summary table of roles and responsibilities presented on page 8 of the Year One Final QAPP is hereby amended to read: 3 Name Roles Responsibilities Affiliation Technical Team Personnel: Dr. Brian Howes Technical Manager Science Oversight SMAST-UMassD Technical Team, Chair Synthesis/Thresholds Roland Samimy Technical Coordinator Science/DEP Coordination SMAST-UMassD Technical Team Surface Water Hydrology Dr. Dave Schlezinger Technical Team N regeneration, SMAST-UMassD D.O.

As previously stated in the Final QAPP, dissolved oxygen mooring deployments are to be conducted during the months of July and August and moorings would typically remain on station for 30 to 60 days. Based on data collected to date, the MEP Technical Team, in consultation with the Massachusetts Department of Environmental Protection (DEP) Technical Specialists, determined that the DO mooring program would be 4 improved by extending the instrument deployment window. During the ~100 mooring placements to date, it is clear that the period of low dissolved oxygen extends beyond the first 2 weeks of September. Therefore the window for acceptable D.O. mooring data will be amended to be from July 1 to September 15. By extending the deployment window for DO instrumentation, it will be possible to capture low DO events occurring in the early weeks of September. This extension of the deployment window will be effective for the summer 2004 field data collection season and does not invalidate or change the accuracy and precision of previous dissolved oxygen data collected for the MEP. Therefore, Table B.6-1 (Habitat Assessment Program, field parameters measured and data objectives) presented on page 79 of the Year One Final QAPP is hereby amended to read: Parameter Method Detection Frequency QC Samples Acceptable Limits %Recovery Macrophytes Video Survey Individual 1 survey Spot checks by diver 95% shoots May-Oct.

Additionally, the second complete paragraph on page 81 has been revised to reflect the mutually agreed upon extension of the deployment period and hereby reads as follows: Dissolved oxygen is a critical indicator of nutrient over-enrichment and eutrophication. The problem with quantifying dissolved oxygen conditions stems from the high temporal variability of this parameter. However, determining the level of oxygen depletion and the duration of low oxygen conditions is a key indicator and one with regulatory implications. Therefore, the Estuary Project will 5 deploy ENDECO/YSI 6600 sensor systems in the target embayments throughout July and September of the field data collection year or possibly in a following second year if necessary. We have extensive experience with using these instruments and they are a routine part of SMAST field Programs. The sensors will also measure temperature, salinity and chlorophyll a. They will be placed within “areas of concern” and other areas throughout each system, as indicated from the long-term monitoring baseline. The sensors will be deployed on fixed moorings generally within the upper reaches of embayments or where baseline water quality monitoring suggests that D.O. depletion may be occurring. The sites will be selected based upon (1) measured dissolved oxygen levels of <4mg/L by water quality monitoring programs or (2) indications based upon algal blooms and circulation that a low dissolved oxygen environment may exist. Sensors will be placed 0.3 m above the sediment surface and will sample at 10-15 minute intervals. Membrane fouling and sensor maintenance will follow manufacturer specifications, but membranes and batteries will be replaced every 30 days. In addition to the above mentioned specific revisions, the Final MEP QAPP has been updated to reflect the third round of prioritization of embayments intended to undergo high end MEP field data collection in summer 2004. A sampling and analysis plan has been developed for each of the embayments listed in the round three prioritization per the agreed upon format developed for embayments in rounds one and two. The embayment specific SAPs (referred to as the Appendix QAPPs) are provided in this document under separate cover to serve as an addendum to the Final QAPP (June 13, 2003).
