Urban Green supported the environmental efforts for the redevelopment of Alta Brewers Hill (previously known at Brewers Hill – Lot 6C and Lot 10N) since 2015, at which time the property consisted of an approximate 5.547-acre surface level parking lot and adjoining landscaped area.  In 2016, Urban Green was contracted by the future developer to develop and oversee the implementation of an EMP to comply with the NFRD and COC recorded for the properties.  Concurrent with the development of the EMP, Urban Green provided technical expertise pertaining to local and state environmental regulations and policies regarding integrating the City of Baltimore, MDE VCP, CHS, OCP, and Waste Management Administration.   

Historically, the Alta Brewers Hill property was part of an expansive bulk storage facility.  From at least 1936 until demolition circa 1963, the Lot 6C portion was utilized as a bulk petroleum storage tank farm; from at least 1914 through 1980, the Parcel 10N portion was developed as a railroad right-of-way. 

Pre-development environmental effort performed by Urban Green included the performance of a site-wide geophysical survey to evaluate for subsurface anomalies, tanks and/or piping, a review of all prior geotechnical and environmental data and development and implementation of a site-wide sampling program to pre-characterize soils for disposal based on contaminant source (e.g. petroleum-impacted, lead- and petroleum-impacted, non-petroleum, PAH-impacted, and native, non-impacted soil), preparation of a City of Baltimore Discharge Permit Application to allow for impacted groundwater, if encountered, to be treated and discharged to an on-Site sewer house connection, preparation of a MDE OCP National Pollution Discharge and Elimination System (NPDES) permit application to allow for non-impacted groundwater, if encountered, to be treated and discharged on-Site, creation of an EMP summary for contractors to use as a guide during construction.

In April 2018, the Excavation Notification and EMP were submitted to the MDE for approval.  The EMP included requirements for soil screening and disposal, groundwater screening and disposal, vapor mitigation (vapor barrier and sub-slab depressurization system), and an environmental containment remedy.  EMP implementation was initiated in July 2019.  Environmental effort performed during the EMP implementation has included on-Site environmental monitoring, including field screening of soils, management of soil disposal manifest, vapor barrier installation inspection, containment remedy installation inspections, daily field reporting (submitted directly to the client) and quarterly reporting.  MDE closure for the Site was issued in November 2020.
