Navigating E-Designations: Overcoming the Challenges of Air Quality and Noise Compliance

Developers are all too aware of the potential pitfalls of purchasing or developing property with known or potential contamination. In New York City, these properties can be subject to E-Designations—zoning regulations that require certain environmental elements to be investigated and addressed prior to development.

Most developers are also aware of the time and financial implications of mitigating the risks tied to such properties: substantial subsurface investigations, laboratory analysis, agency coordination, and even public and community involvement with associated comment periods.

While E-Designations for hazardous materials get all the headlines, secondary players often create more day-to-day friction: air quality and noise. They can have significant impacts on the timing and finances of proposed property redevelopments, even for renovations. In some instances, Air Quality and Noise E-Designations can even halt development planning and proceedings altogether.

Environmental Assessment Statements

Typically, E-Designations are placed on individual properties or groups (blocks) of properties during rezoning actions based on the findings of the mandated City Environmental Quality Review (CEQR) Environmental Assessment Statement (EAS). During the EAS, the developer must determine the impact the proposed redevelopment will have on the surrounding properties, and vice versa. In many cases, if a theoretical impact is identified, air quality screening and noise monitoring may be required. The results are used to assign the E-Designation requirements.

Air quality screening results typically require the proposed redevelopment to protect the surrounding properties from expected emissions by adhering to certain controls, such as minimum exhaust stack heights and setbacks or fuel-type restrictions.

Noise monitoring is quite the opposite, requiring the proposed redevelopment to adhere to certain controls to protect the occupants of the proposed building from the existing ambient and typical noise levels. This might include specific window/wall noise attenuation requirements or alternative means of fresh air ventilation.

Permitting Challenges

Why are screening and monitoring critical for your timeline? New York City’s Office of Environmental Remediation (OER) oversees the E-Designation program, and their approval is a prerequisite for obtaining Department of Buildings (DOB) permits. Collaboration with the OER and obtaining their final sign-off is an essential link in the permitting chain. If a project cannot demonstrate that it meets site-specific air and noise requirements, the DOB cannot issue the permits necessary to begin or conclude construction.

Additionally, there has been an uptick in proposed development projects being denied Support of Excavation (SOE) and foundation permits. These permits, which are necessary for remedial excavations, including project sites associated with the New York State Department of Environmental Conservation Brownfield Cleanup Program, can be denied if the developer has not sufficiently proven their intent to meet Air Quality and Noise E-Designation requirements.

Air Quality and Noise templates are updated regularly, and evaluations are becoming increasingly stringent. It is crucial that developers stay aligned with the OER’s expectations.

Notice to Proceed vs. Notice of No Objection

The OER generally requires submission and approval of both a Hazardous Materials Remedial Action Work Plan (RAWP) and a Final Air Quality and/or Noise Remedial Action Plan (AQNRAP) to issue a Notice to Proceed (NTP). This means all DOB permits related to the construction of a new building are released by the OER and made available to the developer or construction contractor. However, there are tools that enable the progression of remedial-related excavations, SOE, and foundation work to begin prior to approval of a fully signed, stamped, and certified AQNRAP.

Oftentimes, the foundation and SOE plans, as well as the RAWP, are finalized far before the elements required for the AQNRAP (such as window selections, mechanical HVAC designs, and alternate means of ventilation plans) have been completed. In these situations, the OER will not issue an NTP; however, they can issue a Notice of No Objection (NNO) if a draft AQNRAP has also been submitted.

A draft AQNRAP can utilize placeholder information, such as typical window types and acceptable OITC ratings; alternate means of ventilation (AMV), such as trickle vents or ducted fresh air; and mockups of commonly required drawing sets, such as color-coded elevation and window schedule drawings, mechanical plans, and/or AMV plans.

A substantial level of effort is still required to issue this draft report; however, the ability to pull permits and break ground before finalizing all the elements bound by the Air Quality and Noise E-Designation may provide a financial benefit to projects and can shorten the redevelopment timeline.

A Call to Collaborate

While hazardous materials often take center stage in environmental due diligence, Air Quality and Noise E-Designations can just as easily stall a project’s momentum. Successfully navigating these requirements isn’t just about filing paperwork; it’s about strategic timing.

By leveraging tools like the NNO early in the process, developers can break ground and keep the excavators moving while specific design details such as window specs and HVAC heights are finalized. This requires early coordination and collaboration between the OER, environmental consultant, architect, and MEP engineer.

Don’t let an E-Designation be a stumbling block. With the right roadmap, a mindset for agency/developer collaboration, and a clear understanding of the OER’s expectations, you can turn these potential hurdles into the foundation of a successful development.
