! Waste trucking unit cost: $ 18/ ton represents the average incremental cost for trucking RCRA hazardous wastes, compared to the average cost of trucking non hazardous materials, based on OSW triangulation of three data sources on trucking costs, based on average trucking one way distance of 200 miles, which approximately represents the national average distance between RCRA hazardous waste generators, and RCRA permitted hazardous waste treatment, storage, disposal, & recycling facilities ( TSDRFs); see attached spreadsheet for data source and derivation of this unit cost factor. : ! RCRA manifest unit cost: $ 300/ trip represents average manifest paperwork cost per truck shipment over the entire chain of custody from waste generators to waste transporters to waste receivers to filing the manifest with state governments for recordkeeping ( see attached spreadsheet for source and derivation of manifest unit cost).

! Sludge management unit cost: $ 252/ ton represents an average unit cost based on a data sample of sludge management quantities and methods from the USEPA OSW 1996 " National Hazardous Waste Constituent Survey" database, consisting of 27 sludge wastestreams ( 387,000 tons) managed by: ( 1) dewatering, ( 2) phase separation ( filtration), ( 3) stabilization/ chemical fixation, ( 4) incineration, ( 5) energy recovery, and ( 6) landfil ( see attached spreadsheet for the sludge data sample). ( b) ** Wastewater system costs ( capital & O& M) estimated using cost algorithms displayed in another spreadsheet attached to this report.

( b) Ton = 2,000 pounds ( i. e. short ton) ( c) * Based on comparison of the additional unitized ( amortized) costs for compliance with RCRA hazardous waste tank system requirements 40 CFR 264/ 265 Subpart J ( tank secondary containment, tank spill/ overflow controls, leak repair) + Subpart AA ( tank vent control device) + Subpart BB administrative costs + Subpart CC ( tank cover/ roof), compared to the average unit cost ($/ ton of wastewater flow) for operating onsite non hazardous waste unlined surface impoundments; on a unitized basis the RCRA costs represent 119% additional cost ( i. e. relative cost multiplier = 2.119). ( d) Important note: cost estimation algorithms in this table applied in this report for purpose of estimating the cost of managing incremental quantities of spent solvent related wastes at a single facility, rather than for estimating the total cost of managing all waste quantities ( i. e. spent solvent related wastes + other types of solid wastes) which may be generated by a single facility. Because most of the cost estimating algorithms in this table exhibit economies of scale ( i. e. unit costs per pound or per gallon of waste decrease with increasing total waste quantity capacity), at the margin, the costs and cost savings estimated for the incremental quantities of spent solvent related wastes are overestimates of actual costs and potential cost savings. 151 Unit Costs for Estimating Hypothetical Non Hazardous Industrial Wastewater Surface Impoundment Management Costs Source: Unit costs below adopted from the USEPA Office of Solid Waste, Economics, Methods & Risk Analysis Division, " Unit Cost Compendium", 30 Sept. 2000 Annual Wastewater Quantity ( two alternative metric equivalents) Unit Cost for Surface Impoundment Operation kgal/ year tons/ year $/ kgal $/ ton A.

Explanatory Notes: ( a) The " composite average" computed above ( 27%) represents estimated fraction of F001 to F005 spent solvent chemicals which are less than either of the two RCRA " headworks exemption" concentration maximum thresholds ( i. e. 1ppm or 25ppm, depending upon type of chemical   see 40 CFR 261.3( a)( 2( iv)( A) & ( B), respectively), as derived from USEPA 1999 " Toxics Release Inventory" data on concentration of four spent solvent chemicals ( benzene, 2 ethoxyethanol, 1,1,2 trichloroethane, and 2 nitropropane) in industrial wastewaters ( a data background document to the proposed rule contains the TRI data for these four solvent chemicals on which USPEA OSW derived the estimated percentages in this table). ( b) USEPA OSW estimated fractions of < 25ppm concentration range bins in proportion to uniform distribution across TRI defined 1 to 100 ppm range bins, which may result in over restimation of < 25ppm fractions, because there is survey sample evidence that some industrial RCRA waste mixturte chemical concentrations exhibit negatively skewed data distributions   see the RCRA mixture waste chemical concentration histogram on page 75 at: http:// www. epa. gov/ epaoswer/ hazwaste/ id/ hwirwste/ final/ mwanal. pdf 153 Paperwork Unit Cost for the RCRA Hazardous Waste Manifest ( Source: USEPA " Hazardous Waste Manifest Cost Benefit Analysis", prepared for the Office of Solid Waste ( HWID), by Logistics Management Institute, Oct 2000, Table 3 9, page 3 7, http:// www. epa. gov/ epaoswer/ hazwaste/ gener/ manifest/ pdf/ cba rprt. pdf )

On average, 12.3 tons of RCRA industrial wastewater produces 1.0 ton of sludge ( sludge: to: WW ratio = 8.3%).

Explanatory Notes: ( a) * The weighted averages above are weighted according to the annual quanitities ( tons) of wastestreams in the NHWCS database which meet the query criteria. The computation results above are sensitive to whether the non weighted means, medians, or weighted averages for waste specific gravities and waste % solids/ organic matter are applied in the computations, because of differences in numerical values for each of these three alternative measures of central tendency for each NWHCS data subset. NWHCS database sample sizes ( datapoints) for these two factors are ( 1993 USEPA hazardous waste " Biennial Reporting System" benchmark quantities are 220 million tons RCRA industrial wastewater & 15 million tons non wastewater, of which 209,000 tons went to sludge treatment; see http:// www. epa. gov/ epaoswer/ hazwaste/ data/ br93/ na pdf. pdf): Specific gravity % solids/ organic matter ! Industrial wastewaters: 142 NWHCS wastestreams ( 198.0 million tons/ year in 1993) 102 NHWCS wastestreams ( 96.4 million tons/ year in 1993)

! Industrial wastewater sludges: 27 NWHCS wastestreams ( 387,000 tons/ year in 1993) 15 NWHCS wastestreams ( 166,000 tons/ year in 1993)

( b) In comparison to industrial wastewaters & sludges, the typical concentration of solid/ organic matter in raw municipal wastewater is 0.02%, and the typical municipal wastewater treatment raw sludge is 4% ( source:

Food and Drug Administration

[Docket No. FDA-2019-N-0299]

Nonprescription Naloxone Labeling Resources; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing
the availability of a model Drug Facts label (DFL) for nonprescription
naloxone. Naloxone is a drug used to treat opioid overdose. FDA is
making the DFL and supporting data available for use by applicants
seeking approval of naloxone drug products that can be obtained without
a prescription.

FOR FURTHER INFORMATION CONTACT: Sherry Stewart, Center for Drug
Evaluation and Research, Food and Drug Administration, 10903 New
Hampshire Ave., Bldg. 22, Rm. 5494, Silver Spring, MD 20993-0002, 301-
796-9618.

SUPPLEMENTARY INFORMATION:

I. Background

    The increasing incidence of misuse and abuse of illicit and
prescription opioids and the associated risks of addiction, overdose,
and death have resulted in a public health crisis in the United States.
Opioid overdose is characterized by life-threatening respiratory and
central nervous system depression that, if not immediately

treated, may lead to significant morbidity and mortality. When
administered quickly after an opioid overdose, naloxone, an opioid
antagonist, can save lives. Naloxone is currently approved as a
prescription drug, but it is not approved for nonprescription use. As
part of a wide governmental effort to address the national crisis of
opioid overdose deaths, the Agency has identified broader availability
of naloxone, including potential nonprescription availability, as one
means to help reduce overdose deaths.
    To support approval of a drug for nonprescription use, the sponsor
of the drug product typically (among other things) conducts one or more
consumer behavior studies to demonstrate that consumers would be able
to use the drug product safely and effectively in the nonprescription
setting without the supervision of a healthcare professional. Some
stakeholders have identified the need to perform these studies as a
barrier to development of a nonprescription naloxone drug product. To
help address this concern, FDA developed a model DFL for a potential
nonprescription naloxone drug product. The model DFL is intended to
contain adequate information (except for individual device-specific
information, such as how to use a particular injector or spray device,
which would be added by the product sponsor) that a consumer would need
to administer naloxone safely and effectively for its intended use in
the nonprescription setting. Consumer comprehension of the model DFL
has been iteratively tested by an independent research contractor in a
prespecified research design involving over 700 participants across a
wide range of potential nonprescription naloxone users. These
participants included people who use heroin, people who use
prescription opioids, family and friends of people who use opioids,
adolescents, and members of the general public.
    After completion of the label comprehension study, an FDA review
team that was not involved in the design or conduct of the study
reviewed the study report and determined that the comprehension results
are adequate. FDA has determined that the model DFL can be made
publicly available so that sponsors who wish to pursue development of a
nonprescription naloxone product can use the model DFL in their
development program. A sponsor would need to add its device-specific
information to the model DFL and retest that information to demonstrate
that consumers understand the information within the context of the
overall DFL. The model DFL comes in two versions (one for use with a
nasal spray and one for use with an injector), but the device-specific
instructions in each version are placeholders that have not been tested
for comprehension or human factors performance, and sponsors will need
to replace these placeholders with their own device-specific
information and retest it appropriately.
    FDA strongly encourages sponsors of potential nonprescription
naloxone drug products to request a meeting to discuss their
development program with the Division of Nonprescription Drug Products.
For information on sponsor meetings with FDA, sponsors can refer to the
draft guidance for industry ``Formal Meetings Between the FDA and
Sponsors or Applicants of PDUFA Products'' at<EMAIL_ADDRESS>
