Dear Madam or Sir, Please include the following in the next monitoring report that is submitted:
1.) Include a complete executive summary/history. The executive summary/history should also include, but is not necessarily inclusive of, the following:
a. Discuss the site check activities, results and interpretation of the results, b. Discuss the release near the dispensers i. Nature of the release (gas, diesel, kerosene?) ii. Has the leak been repaired/replaced? When and how? iii. Is the system presently leaking? Why or why not? c. Were the lines and dispensers replaced at some time. If yes, when and why? d. Discuss the water supply well sampling events, the results, health risk evaluation results, and a history of actions taken in response to the results,
e. A more detailed discussion of the site risk (public water availability, basements, surface water, etc.) f. All remedial actions taken to date (removing/repairing tanks, lines and/or
dispensers, soil excavation, MMPE/AFVR events, activities in response to water supply well results, etc.). g. Information about other potential sources in the area.
2.) Under the Determination of Groundwater Flow Direction section, give the direction of the vertical component of flow (flowing up or down).
3.) Include the following tables as found in the appendix of Guidelines for Assessment and Corrective Action.
a. Tbl B-1 i. Be specific about which part of the system leaked (tank, line, dispenser) under the “was a release associated with the UST System” column. b. Tbl B-2, c. Tbl B-3, d. Tbl B-8A and B-8B,

i. Also include: the cost per event, the cost per gallon of free product recovered for each event, and the total cumulative cost of all of the
events.. 4.) Table B-4: a. Include the groundwater standards at the bottom of each page. 5.) Table B-5: a. Include the depth of the water supply wells if known. b. Include the date that the receptor survey/updated receptor survey was done at the top of the table. 6.) Table B-7:
a. Include the table at a readable scale. b. Include data vertical down, c. Include groundwater elevation and depth to groundwater for each event.
7.) Include a table of the adjacent property owners/occupants.
8.) Include the field parameters listed under task code 4.031 in the Trust Fund’s Reasonable & Necessary Task Scope-Of-Work Document in a table. 9.) The site map needs to also include the following if applicable: a. All present and former UST systems (tanks, lines, dispensers), ASTs and other potential petroleum sources, i. Label tanks to correlate with the tables. b. Locations of other petroleum releases if within the boundaries of the site map, c. Utilities, d. Basements, e. Property boundaries, f. Soil excavation area(s), g. Location of water supply wells and monitoring wells if within the boundaries of the site map,
h. Legend at a larger readable scale. 11.) Provide groundwater cross-sections that include the following if applicable:
a. Include MW-7 in one of the cross sections, b. Soil, saprolite, and bedrock boundaries and characteristics, c. Groundwater table, d. Monitoring and water supply wells with screen intervals: e. Present and former UST systems (tanks, lines, dispensers), ASTs, and other potential/actual petroleum release areas, f. Soil excavation area(s), g. Contours of groundwater contamination above 2L and gross contaminant levels, h. Buildings, streets, utilities, and basements, i. Vertical and horizontal scales on the figure, j. Vertical and horizontal bar scales in the key, k. Any other pertinent information.

12.) Include the location of the groundwater cross sections on one of the figures.
13.) Provide a figure that includes all soil samples ever taken. Include the following if applicable: a. All soil sample locations ever taken (environmental assessment, site check, closure, assessment, remediation phases), i. Correlate locations with the table. b. Former and present tank systems including tanks, lines, dispensers, and other potential/actual petroleum sources (ASTs, etc.), c. Soil excavation area(s), d. Contour lines of soil contamination above the soil-to-groundwater, residential, and industrial/commercial standards. (Soil samples above the TPH action
levels of 50 ppm gas and 100 ppm diesel should be considered to be above the soil-to-groundwater standards for this figure. Please note that individual risk-based analytical numbers take priority over TPH numbers when determining
the level of soil contamination.). i. Include a set of contour lines for soil samples taken in the unsaturated zone.
ii. Include a set of contour lines for soils in the smear zone. e. Monitoring well and water supply well locations, f. Soil cross-section locations. 14.) Provide soil cross-sections that include the following if applicable: a. Soil, saprolite, and bedrock boundaries and characteristics, b. Soil sample locations, c. Soil excavation area(s), d. Present and former UST systems (tanks, lines, dispensers), ASTs, and other petroleum release/potential release area(s), e. Contours of soil contamination above soil-to-groundwater, residential, and
industrial/commercial standards. (Soil samples above the TPH action levels of 50 ppm gas and 100 ppm diesel should be considered to be above the soil-to-groundwater standards for this figure. Please note that individual risk-based analytical numbers take priority over TPH numbers when determining the level of soil contamination.), f. Groundwater table,
g. Monitoring and water supply wells with screens, h. Buildings, streets, utilities, and basements, i. Vertical and horizontal scales on the figure, j. Vertical and horizontal bar scales in the key, k. Any other pertinent information. 15.) A figure should be provided, correlating to the adjacent property owner/occupant table, that depicts the adjacent properties. 16.) Figure 4: a. Include property boundaries,
b. Include well numbers that are easy to read (blue is difficult to see on paper copies),

c. Include circles with the distances of 250 feet, 500 feet, 1000 feet from the source area.
17.) Include other potential petroleum sources in the area on one of the figures. Include property boundaries. 18.) Include contours of free product boundaries on the groundwater concentration maps. 19.) Include graphs of free product thickness verses depth to groundwater. 20.) Change the blue printing on figures to black or a color that can be easily seen on the paper copies.
21.) Include: a. The amount of contaminant mass that needs to be treated or physically removed (if any),
b. A conceptual site model, c. A conceptual corrective action proposal.
