LRAA: The Locational Running Annual Average (LRAA) is calculated by taking the value of this quarter and the three previous consecutive quarters.
RAA: The System-wide Running Annual Average (RAA) is calculated by taking the average of the Quarterly Average of this quarter and the three previous consecutive quarters.
OEL: The Operational Evalution Level (OEL) is calculated by averaging 2 times this quarter's value and the two previous consecutive quarters.
Both the LRAA and the System-wide RAA is not to exceed 80 µg/L for TTHM and 60 µg/L for HAA5.

DEP’s Water Demand Management Plan identifies six key strategies for managing water demand in New York City, and details specific initiatives to be implemented between now and 2022 in order to achieve targeted water demand reductions. This dataset contains projects that have been funded to date through DEP’s Demand Management Programs and associated water savings. Water savings are in gallons per day (GPD)

This dataset contains annual allocations of dewatered solids or biosolids from a specific dewatering facility to a specific management practice site in dry metric tons. 'Dewatered solids' are the solids remaining in digested sludge after removal of water in a dewatering facility. 'Biosolids', per the US Environmental Protection Agency (EPA), is treated sewage sludge that meets the EPA pollutant, pathogen & vector attraction requirements for land application and surface disposal, and the DEP has certified it with the EPA as such.

Biosolids in this case are also dewatered. Depending on the material being managed (i.e., dewatered solids or biosolids), a 'management practice site' may be one of the following: 1) a third party vendor treatment facility (e.g., composting, dryer, alkaline treatment) that converts the dewatered solids into biosolids for beneficial reuse in various land application practices (e.g., agricultural land application, reclamation site application) or for distribution/marketing as a soil amendment or fertilizer; 2) a direct land application site for agricultural use (typically a farm); or 3) a landfill. The dataset includes the pathogen (disease-causing organism) reduction and vector (an animal capable of transmitting disease such as flies or rodents) attraction reduction options employed as part of the treatment and the type of biosolids class produced, if applicable. There are different biosolids class types, each having specified treatment requirements for pollutants, pathogens and vector attraction reduction, as well as general requirements and management practices,

This dataset contains monthly performance indicators for Wastewater Resource Recovery Facilities (WRRFs) that operate co-digestion and biogas-to-grid programs. The New York City Department of Environmental Protection (DEP) treats the solid component of the City’s wastewater using anaerobic digestion. This biological process produces biosolids, which can be used as fertilizer, and biogas, a renewable energy source.

Co-digestion is the process of digesting food scraps alongside sewage sludge. The biogas generated is used on-site in boilers to heat the digesters and provide space heating. Excess biogas undergoes biogas-to-grid treatment, where it is purified and upgraded to renewable natural gas (RNG). Following purification, the RNG is exported to the natural gas pipeline as a direct replacement to fossil fuels. Excess biogas is flared during temporary system outages of the biogas cleaning system due to maintenance, operational constraints, or emergency events.

The co-digestion and biogas-to-grid program provides a local recycling outlet for food scraps, transforming waste into renewable energy. Together, they reduce greenhouse gas emissions by replacing a portion of fossil natural gas with RNG and avoiding the methane emissions that would occur if the food scraps were disposed of in a landfill.
