DELAWARE EXTREMELY HAZARDOUS SUBSTANCES RISK MANAGEMENT ACT
BASIS AND BACKGROUND DOCUMENT TOXIC SUBSTANCES MAY 1989
CTL020548

BACKGROUND AND PURPOSE
Delaware House Bill No. 555 created the Extremely Hazardous Substances Risk Management Act (EHSRMA) with the goal of preventing catastrophic events caused by chemical substances (para. 77 03) .
Significant concepts defined in the Act include:
o A Catastrophic Event is an event that will cause death or permanent disability to a person just beyond the facility boundary as the result of a single, short-term exposure (para. 7705(c)).
o A toxic substances shall be classified as an Extremely Hazardous Substance if its calculated Substance Hazard Index (SHI) exceeds 8000. SHI is calculated by dividing the equilibrium vapor concentration at 20 C by the Acute Toxicity Concentration (ATC). ATC is defined as the lowest reported concentration that will cause death or permanent disability from a one-hour exposure (para. 7707.(a)). Thus, the SHI is a reflection of both the toxicity and dispersability of the toxic substance.
o The Sufficient Quantity (SQ) is that amount of an EHS that will cause a catastrophic event (para. 7705.(q)).
o The consequences of releases of toxic EHSs shall be determined via atmospheric dispersion calculations assuming average atmospheric conditions for Delaware' (para. 7705.(m)).
o Toxic dose/response relationships are to be used assuming average individuals (para. 7707.(q)).
o SQs are to be calculated assuming a distance of 100 meters between the release point and the facility boundary. SQ's can be adjusted upwards where this separation distance exceeds 100 meters (para. 7708).
It is required that regulations be promulgated to implement this Act (para. 7707). ,, The purpose of this report is to communicate proposed technical bases -for the identification of an EHS and the calculation of an SQ for a toxic substance.
DISCUSSION
PREPARATION OF EHS LIST. A list of toxic EHSs has been compiled consistent with the requirements of the Act and is presented as Table 1. Candidate substances came from a list of "Extremely Hazardous Substances" prepared by the U. S. EPA under Section 302 of SARA Title III (USEPA, 1987) and from a list of "Extraordinarily Hazardous Substances" prepared by the New Jersey Department of Environmental

Protection (NJDEP) under the New Jersey Toxic Catastrophe Prevention Act (TCPA) (NJDEP, 1988).
CHOICE OF ATC AND CALCULATION OF SHI: Three sources of toxicity data were surveyed to determine the appropriate ATC values: the American Industrial Hygiene Association (AIHA) Emergency Response Planning Guideline-3 (ERPG-3) , the New Jersey Acutely Toxic Concentration (ATC), and the EPA Level of Concern (LOC).
ERPG-3. A group of approximately 25 chemical firms has developed a protocol for preparation of community emergency exposure guidelines. AIHA is providing technical oversight of this effort. Three levels of physiological effect are considered, as shown in Attachment 1. For this study, it has been decided that the ERPG3, defined as "The `maximum airborne concentration below which it is believed that nearly all individuals could be exposed for up to one hour without experiencing or developing life-threatening health effect" is the appropriate value to use as the ATC.
New Jersey ATC. In implementing the TCPA, New Jersey defined their ATC as the lowest of (1) the National Institute for Occupational Safety and Health (NIOSH) Immediately Dangerous to Life and Health (IDLH) concentration, (2) the LC^q (defined as the lowest concentration reported to be fatal to humans or animals) or (3) one-tenth of the LC50 (the median lethal concentration).
Environmental Protection Agency LOC. The EPA defines the LOC as one-tenth of the IDLH (or an equivalent estimate of the IDLH) (USEPA, 1987). Consequently, the LOCs were multiplied by a factor of 10 before use in this study to place them on a common basis with the ERPG-3 and the NJ ATC.
These three toxicity measures, where available, are given in Table 1 for the various EHSs. All values are reported as parts per million by volume (ppm-v) of vapor. The order of preference in selecting which value to use is: ERPG-3 first (if available), followed by NJ ATC, with EPA LOC last. ERPG-3s are the preferred choice because the protocol used in their development is believed to be based upon the "best science" currently available for establishing emergency response guidelines.
Ir One additional consideration in the calculation of SHI should be noted. The calculation requires the equilibrium vapor concentration calculated from the substance vapor pressure. However, a number of the EHSs are gases above their critical temperatures, and the concept of vapor pressure is not applicable. For these EHSs, a value of 760 mm Hg (atmospheric pressure) has been used as the vapor pressure in the SHI calculation.
The EHSs in Table 1 are ranked in the order of' decreasing SHI (Table 2, gives the same data sorted alphabetically by EHS name, and Table 3 lists the toxic substances that fell below the 8000 SHI cut-off).

BASIC APPROACH TO CALCULATION OF SQ'S. The Act stipulates that SQs be determined by using atmospheric modeling techniques (assuming average Delaware atmospheric conditions) with toxic exposure dose/response relationships applied to average populations.
Toxic exposures are typically expressed as a dose which is a function of both the concentration and duration of the toxic cloud (Casarett and Doull, 1986). ATCs were defined above without reference to exposure duration. In point of fact, ERPG-3s are based upon a 60-minute exposure, IDLHs are based upon 30 minutes and LC^q's and LCso's pertain to exposure times that vary with the laboratory procedure used in their determination. For the methodology described in this report, a constant exposure time (and, therefore, release duration) of 60 minutes was assumed. This was chosen to be consistent with the basis of the ERPG-3s, the ATC measure of choice, and with the basis for the SHI.
Based upon these concepts, the SQ can now be defined as that quantity of material which, if released over the period of one hour under average atmospheric dispersion conditions, would create an airborne vapor concentration just equal to the ATC at the facility boundary. Thus the threshold fatal concentration is conservatively assumed not to reach off-site personnel.
SQs have been calculated based upon the dispersion model discussed below and are summarized on Table 1.
CHOICE OF ATMOSPHERIC DISPERSION MODEL. The neutrally buoyant, Gaussian dispersion model described in Turner's Workbook (Turner, 1970) was selected for use. This is consistent with the approach taken by the NJDEP (Baldini, 1988; Costanza et al., 1987; NJDEP, 1987) and the EPA (EPA, 1987). While vapors produced by some of the EHSs will be heavier than air at the point of release, they will be rapidly diluted as they disperse. Vapors diluted to near the ATC (on the order of hundreds to a few thousands of ppm-v) will not be appreciably denser than the ambient air. Thus, the use of a neutrally buoyant model is warranted.
The simplification of the general dispersion formula follows that documented by Turner (Turner, 1970). The following equation relates release rate, downwind distance, and vapor concentration:
C = Q / (p * sy * sz * U)
where:
C is the vapor cloud concentration at its centerline Q is the release rate in g/sec, U is the wind speed in m/sec, p equals 3.141, and Sy and sz are the dispersion coefficients.
in g/m3,
CTL020551

The dispersion coefficients are evaluated as a function of distance downwind from the release point using the equations given on page G-6 of the EPA manual (USEPA, 1987). It has been decided to use the equations for urban conditions. These equations produce dispersion coefficients that are larger than the corresponding open-country (rural) equations and result in lower calculated vapor concentrations at a given distance. However, the urban coefficients are the more appropriate for use in typical industrial and dense residential areas.
DETERMINATION OF AVERAGE ATMOSPHERIC CONDITIONS. The Act permits the use of average atmospheric (meteorological) conditions when calculating dispersion of the release cloud. Three factors define unique atmospheric conditions for dispersion modeling purposes:
o Wind direction determines the segment of the surrounding population that is exposed to a particular release. Since we are dealing with a hypothetical facility, it is convenient to assume an even population distribution about the facility and, thereby, remove wind direction from further consideration.
o Wind speed directly affects both the speed with which the cloud travels downwind and the rate of dilution of the cloud.
o Atmospheric stability is a measure of the turbulence in the atmosphere; the lower the stability, the higher the turbulence, and the more rapid the dispersion of the cloud.
Standard meteorological data sets are available as joint probability distributions of wind speed, direction and atmospheric stability, often as a function of the season of the year. Wind speeds are grouped into six ranges spanning from about 0 up to about 13 m/sec (or about 30 miles/hr). Stability readings are grouped in six classes, assigned the letters A through F. Table 4 summarizes ten years of Wilmington area meteorological data.
It was not initially apparent how the concept of average meteorological conditions could be implemented. While calculation of a weighted-average wind speed would be straightforward, the concept of average stability cTass was a bit more difficult to grasp. Greaterthan-C-but-less-than-D stability was nonsensical. As a result, the following approach was developed:
1. Assume a release rate and a downwind distance (the values assumed are not critical to the analysis). Calculate the concentration resulting from each combination of speed and stability. Table 5 shows the results assuming a release rate of 100 g/sec and a downwind distance of 100 meters.
2. Create a table summarizing the calculated concentration and the fractional probability of occurrence for each wind speed/stability combination.
CTL020552

3. Re-sort the data so that the highest calculated concentration is at the top of the table.
4. Add the probabilities to create cumulative probability distributions both from the bottom up and the top down. Find the wind speed/stability combination that has approximately equal probabilities of worse combinations and better combinations occurring (i.e., higher concentrations and lower concentrations). Ignore combinations with zero probability of occurrence.
Table 6 shows the finished table and illustrates that the "average" meteorological conditions in the Wilmington area are 4.3 m/sec speed and D stability. The cumulative probability of all worse combinations is about 0.42; the cumulative probability of all better combinations is about 0.40, and the probability of the "average" condition is about 0.18.
Thus, the "average" condition is defined as that with equal probability of occurrence of less favorable and more favorable conditions.
SUMMARY OF ASSUMPTIONS. The methodology described in this report requires a number of simplifying assumptions to permit such a generalized approach to the calculation of SQs. The more significant assumptions are summarized here:
o Continuous, steady-state release for duration of 1 hour,
o All-vapor release (no liquid pool is formed),
o Release at ambient temperature,
o No momentum effects (no initial velocity for release),
o Ground-level release and receptors,
o No deposition or reaction of cloud vapor,
o Neutrally buoyant cloud,
o Urban dispersion coefficients, and
o No mitigating design or operating features to limit the rate or duration of the leak or to minimize its transport beyond the facility boundary.
ADJUSTMENT OF SQ FOR SEPARATION DISTANCES. The Act permits increasing the SQ where the actual distance between the release point and the facility boundary exceeds 100 meters. This correction can be easily made within the dispersion calculations. It is proposed that the multipliers given in Table 7 be applied to the base SQs (i.e., those
CTL020553

determined for 100m separation distance) where greater distances exist.
SUMMARY. A methodology has been developed for calculating Sufficient Quantities of toxic Extremely Hazardous Substances as defined in the Extremely Hazardous Substances Risk Management Act. The methodology complies with the requirements of the Act and is based on sound, demonstrated technology.
