to address the scoping needs. EPA is releasing this draft IRIS 
Assessment Plan for public comment at least 30 days in advance of a 
public science webinar planned on May 23, 2018.

DATES: The 30-day public comment period begins April 16, 2018, and ends 
May 16, 2018.

ADDRESSES: The IRIS Assessment Plan for Ammonia and Ammonium Salts, 
will be available via the internet on IRIS' website at https://cfpub.epa.gov/ncea/iris2/chemicalLanding.cfm?substance_nmbr=422 and in

SUPPLEMENTARY INFORMATION: 

I. Background Information on IRIS Assessment Plans

    EPA's IRIS Program is a human health assessment program that 
evaluates quantitative and qualitative risk information on effects that 
may result from exposure to chemicals found in the environment. Through 
the IRIS Program, EPA provides the highest quality science-based human 
health assessments to support the Agency's regulatory activities and 
decisions to protect public health. As part of scoping and initial 
problem formulation activities prior to the development of a draft 
assessment, the IRIS Program carries out a broad, preliminary 
literature survey to assist in identifying health effects that have 
been studied in relation to the chemical or substance of interest, as 
well as science issues that may need to be considered when evaluating 
toxicity. This information, in conjunction with scoping needs 
identified by EPA program and regional offices, is used to inform the 
development of an IRIS Assessment Plan (IAP).
    The IAP communicates the plan for developing each individual 
chemical assessment to the public and includes summary information on 
the IRIS Program's scoping and initial problem formulation, objectives 
and specific aims for the assessment, and a PECO (Populations, 
Exposures, Comparators, and Outcomes) for the systematic review. The 
PECO provides the framework for developing literature search strategies 
and inclusion/exclusion criteria, particularly with respect to evidence 
stream (i.e., human, animal, mechanistic), exposure measures and 
outcome measures. The IAP serves to inform the subsequent development 
of chemical-specific systematic review protocols, which will be made 
publicly available.

II. Public Webinar

    In order to allow for public input, EPA is convening a public 
webinar to discuss the draft IRIS Assessment Plan for ammonia and 
ammonium salts on May 23, 2018. Specific teleconference and webinar 
information regarding this public meeting will be provided through the 
IRIS website (https://www.epa.gov/iris) and via EPA's Human Health Risk 
Assessment (HHRA) and IRIS listservs. To register for the HHRA or IRIS 
listserv, visit the IRIS website (https://www.epa.gov/iris) or visit
