4 ntroduction This data review covers 22 air samples listed on the cover sheet including dilutions and reanalysis as applicable. The analyses were per ASTM D7614 for Hexavalent Chromium. This review follows the Air Monitoring Program Quality Assurance Project Plan, Area 1, Phase 1 Development, Version 1, Baltimore Works Site, Baltimore, Maryland (March 2014) and a modified outline of the USEPA Contract Laboratory Program National Functional Guidelines for norganic Superfund Data Review (January 201 0). A qualification summary table is provided at the end of this report if data has been qualified. Flags are classified as P (protocol) or A (advisory) to indicate whether the flag is due to a laboratory deviation from a specified protocol or is of technical advisory nature. The following are definitions of the data qualifiers: U J R NJ UJ A P ndicates the compound or analyte was analyzed for but not detected. ndicates an estimated value. Quality control indicates the data is not usable. Presumptive evidence of presence of the compound at an estimated quantity. ndicates the compound or analyte was analyzed for but not detected. The sample detection limit is an estimated value. ndicates the finding is based upon technical validation criteria. ndicates the finding is related to a protocol/contractual deviation. None ndicates the data was not significantly impacted by the finding, therefore qualification was not required. V:\LOGN\ERM\HARBOR PONT _HONEYWELL \ A6_ER4.DOC 2

This review follows the Air Monitoring Program Quality Assurance Project Plan, Area 1, Phase 1 Development, Version 1, Baltimore Works Site, Baltimore, Maryland (March 2014) and a modified outline of the USEPA Contract Laboratory Program National Functional Guidelines for norganic Superfund Data Review (January 201 0). A qualification summary table is provided at the end of this report if data has been qualified. Flags are classified as P (protocol) or A (advisory) to indicate whether the flag is due to a laboratory deviation from a specified protocol or is of technical advisory nature. The following are definitions of the data qualifiers: U J R NJ UJ A P ndicates the compound or analyte was analyzed for but not detected. ndicates an estimated value. Quality control indicates the data is not usable. Presumptive evidence of presence of the compound at an estimated quantity. ndicates the compound or analyte was analyzed for but not detected.

90 ntroduction This data review covers 11 air samples listed on the cover sheet including dilutions and reanalysis as applicable. The analyses were per ASTM for Hexavalent Chromium. This review follows the Air Monitoring Program Quality Assurance Project Plan, Area 1, Phase 1 Development, Version 1, Baltimore Works Site, Baltimore, Maryland (March 2014) and a modified outline of the USEPA Contract Laboratory Program National Functional Guidelines for norganic Superfund Data Review (January 2010). A qualification summary table is provided at the end of this report if data has been qualified. Flags are classified as P (protocol) or A (advisory) to indicate whether the flag is due to a laboratory deviation from a specified protocol or is of technical advisory nature.

113 ntroduction This data review covers 22 air samples listed on the cover sheet including dilutions and reanalysis as applicable. The analyses were per ASTM for Hexavalent Chromium. This review follows the Air Monitoring Program Quality Assurance Project Plan, Area 1, Phase 1 Development, Version 1, Baltimore Works Site, Baltimore, Maryland (March 2014) and a modified outline of the USEPA Contract Laboratory Program National Functional Guidelines for norganic Superfund Data Review (January 2010). A qualification summary table is provided at the end of this report if data has been qualified. Flags are classified as P (protocol) or A (advisory) to indicate whether the flag is due to a laboratory deviation from a specified protocol or is of technical advisory nature. The following are definitions of the data qualifiers: U J R NJ UJ A P ndicates the compound or analyte was analyzed for but not detected. ndicates an estimated value. Quality control indicates the data is not usable. Presumptive evidence of presence of the compound at an estimated quantity. ndicates the compound or analyte was analyzed for but not detected. The sample detection limit is an estimated value. ndicates the finding is based upon technical validation criteria. ndicates the finding is related to a protocol/contractual deviation. None ndicates the data was not significantly impacted by the finding, therefore qualification was not required. V:\LOGN\ERM\HARBOR PONT_HONEYWELL \323 30A6_ER4.DOC 2
