THE HAZARDOUS FACILITY SCREENING PROCEDURE
This section works through a step-by-step guide on how to use the Hazardous Facility Screening Procedure, following the steps shown in Figure 2 and using a series of worksheets. These illustrate the HFSP’s individual steps and longhand calculations. A computer package is being developed to speed up the calculations. Step 1: Assemble Site-specific Information
Site specific information is an essential component of the HFSP. Because it deals with effects, any sensitive land uses or environmental features on or near the site need to be noted. An example of a Site Information Sheet is Worksheet 1. Step 2: Compile Hazardous Substances Inventory
To use the Hazardous Facility Screening Procedure, it is necessary to create a full inventory of hazardous substances held on a site, including substances that are only stored or used temporarily such as waste hazardous substances. The inventory should list: (i) the names (including proprietary names and suppliers where UN classifications of all the hazardous substances on the site; and (iv) whether the substance is used or stored. A form to assist with this task is Worksheet 2. It is noted that the HFSP uses the standards units of tonnes (for solids, liquids and liquefied gases) and m³ (for compressed gases). It is therefore sometimes necessary to convert substance quantities to these units. In the case of liquids, it is necessary to apply the specific gravity (or density) to convert litres to kilograms, or m³ to tonnes. The specific gravity is the specific weight of a liquid in relation to that of water. Therefore, a liquid with a specific gravity of greater than 1.0 sinks, while a liquid with a specific gravity of less than 1.0 will float on water. For example, 1000 litres of petrol weigh approximately 800kg or 0.8 tonnes. Hazardous Facility Screening Procedure - Appendix G South Waikato District Council
Operative District Plan
Conversions of quantities are also necessary where a substance is diluted, or mixed with another substance. In this instance, only the percentage of the pure substance in the dilution or mixture is accounted for. For example, if it is proposed to store 10 tonnes of a substance that has a concentration of 30%, the proposed quantity on Worksheet 2 should be 3 tonnes. Exceptions to this are corrosives (UN Class 8) and oxidising substances (UN Class 5), where the UN Class is sometimes directly applied to specific commercially available concentrations. In these instances, conversions are only applied when these commercially supplied concentrations are further diluted for specific purposes. Pesticides are also substances which are commonly available as diluted commercial products. The UNRTDG (1993) lists a range of pesticides and their dilutions, and their related Packaging Groups in Class 6.1 in terms of a human poison rating. If a substance is in a mixed form, proposed quantities for the percentage of pure substance in the mixture should be listed. In cases where synergistic effects result in a mixture that is more hazardous than its components, the mixture may need to be subjected to appropriate testing procedures to obtain the necessary information, unless relevant information is readily available. It is also important to note that small packages are generally treated the same as bulk quantities. While small packages or containers reduce the risk of a major spill, they may still react like bulk quantities in some emergencies. For this reason, a conservative approach has been taken, especially as the HFSP generally does not apply to retail outlets. In some cases, it may be difficult to decide whether a substance is in use or storage. Generally, the HFSP considers a substance in use when the full amount of the substance is used at any one time, for example as an acid bath. A substance that is taken from a container and used in small amounts while its bulk continues to be stored would be rated as being storage. Select “Priority Status” Substances
Often, numerous hazardous substances are held on a site, and it is time-consuming to prepare a full classification of all of them. It is neither practical nor necessary to submit every substance to the HFSP; therefore the following “common sense” guide-lines apply for sites where multiple hazardous substances are held, to assist in defining those which have “priority status”: if there are ten or fewer substances on site, the HFSP is carried out on all substances unless it is evident that one single substance is likely to exceed the relevant trigger levels in the Consent Status Matrix (in which case the proposal would require a consent application); Hazardous Facility Screening Procedure - Appendix G South Waikato District Council

if there are more than ten substances on site, the HFSP is carried out on those substances which are highly or extremely dangerous; and/or are held in quantities 10% of the total stock of hazardous substances listed in the inventory (Worksheet 2).

Collate Substance Specific Information
It is an essential component of the HFSP to assign a hazard level for each Effects Group to the hazardous substances held on the site. To do so, it is necessary to collect a range of information about the substances, including UN classifications. The Hazardous Substance Worksheet in Worksheet 3 has been designed to help with the task of recording the information required to classify substances into Effects Groups and hazard levels. This information can be extracted from the UN Recommendations on the Transport of Dangerous Goods (UNRTDG) 8th edition, Material Safety Data Sheets, national and international databases, and text/reference books such as those listed in the table labelled “Information Sources for Hazardous Substances”. Occasionally, data on hazardous substances can only be found in units other than those required on Worksheet 3. Some frequently used conversion factors are provided . Where the necessary information to carry out this step is not readily available from public information sources, a precautionary approach should be taken, and the substance should be assigned at least a medium hazard level for the Fire/Explosion and Human Health Effects Groups, and a high hazard level for the Environmental Effects Group. These hazard levels are deemed appropriate because: in general, assessment of hazardous substances focuses on health effects and explosive or flammable properties. If a substances rates highly in these categories, this information is usually readily available. Therefore, it is considered reasonable to assign a medium hazard level in the Fire/Explosion and Human Health Effects Groups for those substances where this information is not readily available; in contrast, information on environmental effects is often lacking. The precautionary approach therefore dictates that a high hazard level should be chosen where no information is available. As the collation of this information is one of the more time-consuming parts of the HFSP, relevant information for some commonly used hazardous substances is provided in the table labelled “Hazardous Substance Profiles”. Hazardous Facility Screening Procedure - Appendix G South Waikato District Council
Operative District Plan
Identify Effects Groups and Hazard Levels
For the purposes of the HFSP, the effects of substances are categorised into three groups: Fire/Explosion Effects: concerned with damage to property, the built environment and safety of people; Human Health Effects: concerned with the well-being, health and safety of people; (iii) Environmental Effects: concerned with damage to ecosystems and Each Effects Group is divided into four hazard levels: The division into low, medium, high and extreme hazard levels in each of the Effects Groups (Fire/Explosion, Human Health and Environmental) is predominantly based on the UN (United Nations) classification system for hazardous substances as outlined in the UN Recommendations on the Transport of Dangerous Goods (UNRTDG), 8th edition, and the classification proposed by the Organisation for Economic Cooperation and Development (OECD) for health and environmental effects1. It is important to note that the above classification systems are inadequate for assigning Effects Group hazard levels to certain hazardous substances, particularly toxic substances (Class 6.1), toxic gases (Class 2.3) and environmentally toxic substances (Ecotoxic Class). For the purposes of the HFSP, the classification of these substances (Classes 6.1, 2.3, and Ecotoxic) has been refined to account for extremely hazardous substances. (ii) Environmentally damaging substances have been placed into the “Ecotoxic” class. Foodstuffs such as milk are an example of an environmentally damaging substance. (iii) Hazardous substances lists based on the UN Classification System often only list the primary hazard of a substance and sometimes one subsidiary hazard, although a substance may have different effects in each of the Effects Groups. For example, a single substance may present: United Nations, 1993. Recommendations on the Transport of Dangerous Goods, Eighth Revised Edition. New York, United Nations. European Community, 1993. Official Journal of the European Community, No. L 110A/68. Hazardous Facility Screening Procedure - Appendix G South Waikato District Council
Operative District Plan
Hence, the HFSP allows for the fact that many substances may fit into more than one Effects Group, which is similar to the approach taken in the proposed HSNO legislation. Hazardous substances (including raw materials, product and wastes) can be classified into Effects Groups and assigned a hazard level for each Effects Group with the help of the table labelled Classification of Hazardous Substances, which lists UN Classes, Packaging Groups and other relevant information. It should be noted that the HFSP also accounts for combustible liquids such as cooking oils that are not usually assigned a UN Class rating. The classification of substances or assignment of hazard levels is, in the first instance, carried out according to their UN classification. For example, a UN Class 8, Packaging Group II substance is always assigned a medium Human Health Effects Group hazard level and a high Environmental Effects Group hazard level. Only when the UN classification does not account for an Effects Group, or the substance does not have a UN rating, should other information be used to classify the substance. Effects Groups and corresponding hazard levels are then recorded in the column marked "Step 4" on the "Summary Sheet for Manual HFSP Calculations" in Worksheet 4. Find Base Threshold Quantities
The Base Threshold (B) is a pre-calibrated quantity. It is the amount of a substance that has been assessed as generating no significant off-site effects in a heavy industrial area before site- and substance-specific considerations have been taken into account. These aspects are addressed through the application of Adjustment Factors. Base Thresholds corresponding to the hazard levels in each Effects Group are listed in Table 1. For example, in the Fire/Explosion Effects Group [Sub-category Flammables], non-significant off-site effects in a heavy industrial area would be represented by Base Thresholds of: 100 tonnes of a combustible liquid, which has a low hazard level in the 30 tonnes of a Class 3, Packaging Group III substance, which are flammable liquids with a medium hazard level in the Fire/Explosion Hazardous Facility Screening Procedure - Appendix G South Waikato District Council
Operative District Plan
The Base Thresholds for each substance used or stored on the site are found in Table 1 and recorded in the column marked "Step 6" on the "Summary Sheet for Manual HFSP Calculations" in Worksheet 4. Find Adjustment Factors
Adjustment Factors (FF, FH and FE) are used to multiply the Base Threshold quantities in order to take account of the substance properties and specific circumstances on each site which will influence the severity of any potential effect. This multiplication yields the Adjusted Threshold (T)(see Step 8). Factors differ for each of the Effects Groups, and take into the pressure and temperature required for storage and usage; separation distances to the site boundary; (vi) the environmental sensitivity of the site location. For each Effects Group, different types of Adjustment Factors are relevant. For example, for the Fire/Explosion Effects Group, the temperature is relevant, while for the Human Health Effects Group, proximity to a potable water resource is important. Table 2 lists the pre-calibrated Adjustment Factors to be used for each Effects Group. In some instances, more than one Adjustment Factor within each Effects Group will need to be applied to a substance. Where this is the case, the Adjustment Factors are multiplied to generate one combined Adjustment Factor (FF, FH or FE) for each Effects Group, and the Base Threshold is then multiplied by that one Factor. The Adjustment Factors for each substance are recorded in the column marked "Step 7" on the "Summary Sheet for Manual HFSP Calculations" in Worksheet 4.

Hazardous Facility Screening Procedure - Appendix G South Waikato District Council
APPX G - 11
Operative District Plan
Step 8: Calculate Adjusted Threshold Quantities
The Adjusted Threshold (T) is calculated for each Effects Group by multiplying the Base Threshold (B) by the relevant Adjustment Factor (FF, FH, FE), as follows: T = B x FF provides the Adjusted Threshold for a substance in the Fire/Explosion Effects Group. T = B x FH provides the Adjusted Threshold for a substance in the Human Health Effects Group. T = B x FE provides the Adjusted Threshold for a substance in the Environmental Effects Group. Adjusted Thresholds (T) for each substance should be recorded in the column marked "Step 8" on the "Summary sheet for manual HFSP calculations" in Worksheet 4. Step 9: Calculate Effects Ratios
Effects Ratio (R) is a dimensionless number. It is obtained by dividing the quantity of a substance (Q) that is proposed to be used or stored on a site by the Adjusted Threshold (T): The Effects Ratio (R) for each substance needs to be recorded in the column marked "Step 9" on the "Summary Sheet for Manual HFSP Calculations" in Worksheet 4. The Effects Ratio fulfils two important purposes: by using a dimensionless ratio of the proposed quantity of a hazardous substance over the Adjusted Threshold instead of Adjusted Threshold itself, it is possible to aggregate the effects presented by multiple substances held on the same site. Hence, it becomes possible to assess the cumulative potential effects which may be created by several substances present on the same site and which have similar hazardous properties; it forms the basis of defining the trigger levels in the Consent Status Matrix which are used to determine the consent status of a particular facility. Whether or not a proposed facility requires a resource consent is determined by assessing whether the calculated Effects Ratios exceed the trigger levels in the Consent Status Matrix. Hazardous Facility Screening Procedure - Appendix G South Waikato District Council
APPX G - 12
Operative District Plan
Step 10: Sum the Effects Ratios to Find the Total Effects Ratio
When assessing several hazardous substances on a site, it is necessary to add the Effects Ratios within each Effects Group together. When carrying out a manual calculation, this is done with the use of Worksheet 5. Step 11: Determine Consent Status Against Consent Status Matrix
The sum of all Effects Ratios within each Effects Group determines the consent status of a particular site when compared against the Effects Ratio trigger levels in the Consent Status Matrix for that Effects Group. In most cases the same trigger value would cover all Effects Groups; in these situations, only the highest Effects Ratio in any of the three Effects Groups needs to be considered to identify the consent status, for example, whether a hazardous facility or activity is permitted, controlled or discretionary. However, there may be situations where a council chooses to differentiate between Effects Groups, in which case the Effects Ratios for the identified Effects Groups are relevant.

LIST OF RECOGNISED CARCINOGENIC SUBSTANCES
The following list of carcinogenic substances and activities has been sourced from a Woodward Clyde Ltd document. It is based on the following publications: International Agency for Research on Cancer (IARC), World Health Organisation: Monographs volumes 1-55, 1972-1992 and Supplement 7,1987. US Department of Health and Human Services, National Toxicology Programme (NTP): Sixth Annual Report on Carcinogens, 1991. IARC classify carcinogens and suspected carcinogens into three categories: is for substances for which there is sufficient evidence for a causal relationship with cancer in humans. is for substances for which there is a lesser degree of evidence in humans but sufficient evidence in animal tests, or degrees of evidence considered appropriate to this category (probable human carcinogen). is for substances for which there is sufficient evidence in animal tests, or degrees of evidence considered appropriate to this category (possible human carcinogen). The IARC and NTP lists in Part I are combined as far as is possible, but some anomalies may exist. Excluded from the list are IARC Category 3 carcinogens for which assessment evidence is limited.
