All City Leadership Secondary School Science Lab - Brooklyn

  • As part of our Due Diligence process, SCA performs extensive studies and investigations to determine the environmental conditions of every site. These studies and investigations go well beyond the requirements of typical industry practices since we are charged with constructing schools that are environmentally safe. Further, we design and implement comprehensive remedial measures that will ensure a safe environment for the life of the school. Our level of care is what sets us apart from others:

    • The SCA never performs asbestos removal, lead paint removal or any other high-risk work in occupied school buildings
    • Environmental experts verify that asbestos, lead paint and other hazardous materials have been removed and that schools areas are safe
    • Our Brochure about Environmental Issues in Construction describes the protocols that the SCA follows to meet legally required standards and protect the school environment.

    If you have any questions about environmental issues during construction, please email ERC.

    The following SCA protocol has been developed for Environmental Due Diligence of schools considered for lease renewals:

    I. Conduct Environmental Due Diligence

    A. Phase I Environmental Site Assessment (ESA) includes the following:

    1. Visual inspection of property and surrounding area
    2. Interview of landlord and occupants
    3. Review of commercially available regulatory databases and historical land use maps
    4. Review of public documents and records indicating past uses of the property

    If a Phase I ESA was already performed by SCA, a Site Inspection (SI) will be conducted. This includes a visual inspection of the property and surrounding area and interview of the landlord and occupants. A regulatory database review may also be conducted, as appropriate.

    B. Based on the findings of the Phase I ESA/SI, SCA will perform Indoor Air Quality Testing (IAQ) of selected Volatile Organic Compounds using EPA Methodology TO-15. If warranted, a soil vapor intrusion survey will be conducted, which may include sub-slab soil vapor sampling and/or additional Indoor Air Quality (IAQ) testing.

    II. Handling of Environmental Site Assessment Data

    A. Upon verification of the laboratory data from the IAQ testing that indicate the concentration of a chemical substance exceeds the applicable New York State Department of Health (DOH) Air Guideline Value (AGV), and is suggestive of soil vapor intrusion, SCA will:

    1. Immediately contact the New York City Department of Health and Mental Hygiene (DOHMH) for consultation and guidance and may also contact the New York State Department of Health (NYSDOH).
    2. Immediately inform the school principal(s), the Director of DOE Environmental Health and Safety, the district superintendent, the District Community Education Council President, School Parent Association, local elected officials, and other concerned parties (e.g. UFT and other unions representing school staff) of:
    3. Environmental conditions and test results, and
      Plan for further investigation and potential sampling, if necessary.

    4. Assist the school principal(s) in scheduling a meeting with the school community as soon as practicable following receipt of confirmed test results.
    5. Immediately conduct confirmatory IAQ sampling if any initial test results exceed an AGV.

    III. Remediation Recommendations

    A. If at any point during the investigation, the SCA determines that mitigation measures involving significant construction-related activities are required to render the school suitable for continued use, SCA will announce its intent to relocate the school on a temporary or permanent basis and will immediately begin to explore alternative locations. Relocation may be necessitated by, among other reasons, the installation of a sub-slab depressurization system for intercepting subsurface vapors beneath the building. Notification of interested parties will proceed in the same manner as described in paragraph II above.

    B. If SCA determines that mitigation measures can be accomplished without disrupting school activities, SCA will complete its investigation and develop a course of action.

    The following SCA protocol has been developed for Environmental Due Diligence of schools considered for new leases:

    I. Conduct Environmental Due Diligence

    A. Phase I Environmental Site Assessment (ESA) includes the following:

    1. Visual inspection of property and surrounding area;
    2. Interview of landlord and occupants;
    3. Review of commercially available regulatory databases and historical land use maps; and
    4. Review of public documents and records indicating past uses of the property.

    B. Based on the findings of the Phase I ESA, SCA may perform a Phase II Investigation consisting of Indoor Air Quality Testing (IAQ) of selected Volatile Organic Compounds using EPA Methodology TO-15. If warranted, a soil vapor intrusion survey will be conducted, which may include sub-slab soil vapor sampling and/or additional IAQ testing.

    C. Additional environmental media may be sampled and tested (i.e., soil, soil vapor, and/or groundwater) as part of the Phase II Investigation if construction activities are anticipated to penetrate the foundation walls or slab on grade, ground surface, or the subsurface.

    II. Handling of Environmental Site Assessment Data

    A. Upon verification of the laboratory data from the IAQ testing that indicate the concentration of a chemical substance exceeds the applicable New York State Department of Health (DOH) Air Guideline Value (AGV), and is suggestive of soil vapor intrusion, SCA recommends appropriate engineering controls or mitigation measures necessary to render the building suitable for use as a school.

    B. Data collected on other environmental media are compared to applicable or relevant regulatory standards or guidelines. If warranted, additional recommendations are provided to address these media during construction activities. Recommendations to the landlord regarding the need to comply with storage tank regulations or to report petroleum spills to the New York State Department of Environmental Conservation (NYSDEC) are also provided.

    Below are the Environmental Due Diligence Reports for 31 Leased School Facilities.

    ​The NYC Department of Education has closed the building at 3200 Jerome Avenue that until June 2011, was the location of P.S. 51 Bronx (Bronx New School). Beginning in September, the school’s new location will be at 695 East 182nd Street. The school is being moved because levels of a chemical known as TCE (trichloroethylene) were above the New York State Air Guideline and DOE determined that the old location could not be effectively remediated before the start of the new school year. As a service to current and former parents of children and to current and former school staff, we have established this web page to provide information relating to the environmental testing that was performed, health questions about TCE, and the new school location.
