As a part of the research, there should be a determination as to whether or not engineered nanomaterials pose risks and how would the research be used in making regulatory decisions. Engineered Nanomaterials is used to identify chemicals and other materials that are intentionally designed to have special properties because of their tiny size, shape, and other characteristics and to distinguish them from other materials, such as ocean spray, soot, or fine particles, which are about the same size but are not intentionally designed. The report summarizing the panel's recommendations should be available by the end of May.

EPA released an update of EJSCREEN, the Agency's publicly available award-winning environmental justice screening and mapping tool. EJSCREEN uses high resolution maps and a methodology for combining datasets to identify environmental burdens on vulnerable populations. This update is an important refresh of the environmental and demographic data contained in EJSCREEN and enhances the tool by adding new and improved functionality. An exciting new feature of the update is the addition of climate change indicators. Users can now add flood and sea level rise data for the first time. EPA will continue to expand the climate change indicators in upcoming updates. EPA's Risk-Screening Environmental Indicators (RSEI) data is also now an available map layer. To better support states and other technical users of EJSCREEN data, EPA has built an improved data dictionary and created downloadable data at the census tract level. Additional enhancements include improved source data on locations (ex: Superfund sites) and the ability to bring in shape files. This will allow users to use the data in various ways to meet their needs.

EPA is updating its Safer Chemical Ingredients List (SCIL), a living list of chemicals by functional-use class that EPA's Safer Choice program has evaluated and determined meet the Safer Choice Standard. In this update, EPA is adding 22 chemicals to the SCIL. To expand the number of chemicals and functional-use categories on the SCIL, EPA encourages manufacturers to submit their safer chemicals to EPA for review and listing on the SCIL. In support of the Biden-Harris Administration's goals, the addition of chemicals to the SCIL incentivizes further innovation in safer chemistry, which can promote environmental justice, bolster resilience to the impacts of climate change, and improve water quality. Chemicals on the SCIL are among the safest for their functional use.

Developed by FEMP, eProject Builder produces ESPC task order schedules and provides a secure online system for easily accessing, tracking and reporting ESPC project data through the life of the contract for your portfolio of projects. Most of the work required in the form of data entry is done by the ESCO, as with the current TO and proposal process. FEMP anticipates little or no additional work expected from agency contracting officers.

A free web-based system for entering and tracking energy savings performance contracting (ESPC) data through the life of a project. Developed by FEMP, eProject Builder produces ESPC task order schedules and provides a secure online system for easily accessing, tracking and reporting ESPC project data through the life of the contract for your portfolio of projects. Will introduce energy service companies, their customers, and other interested parties to ePB, covering the benefits of using ePB, project workflow, a walk-through of the data template, and a live demonstration.

eProject Building 3.0 expands the tool's capability to accommodate two project types, utility energy service contracts (UESCs) and direct-funded projects, in addition to ePB's traditional focus, energy savings performance contracts (ESPCs). While it was technically possible to use ePB for these project types before, the modifications make the tool considerably "friendlier" for users pursuing UESCs and direct-funded projects. Some of the modifications relate primarily to terminology, but there are also functional changes. As an example, savings "guarantees" are eliminated for UESCs, and direct-funded projects do not include loan amortization schedules. In addition, ePB version 3.0 provides a new project data report output that can be directly uploaded to FEMP's EISA 432 Compliance Tracking System (CTS) to populate the CTS Initiated Projects Report.
