Port Pirie Smelting Facility (Lead-In-Air Concentrations) Act 2013

The Act centres on a small set of interlocking legal concepts and temporal definitions. Each is set out in the text and controls how the statutory protections operate.

• Company: The Act applies to the named corporate entity, Nyrstar Port Pirie Pty Ltd, and its successors and assigns (s 3(1)). The Act’s protections and obligations attach to that entity, not generically to any smelter operator.

• Relevant environmental authorisation: The Act treats as central any environmental authorisation under the Environment Protection Act 1993 that applies to the Company’s operations at the plant (s 3(1)). The Act draws a distinction between a “relevant environmental authorisation”, which is an authorisation under the Environment Protection Act 1993, and a “relevant authorisation” used in s 5 (see s 5(5)), which includes other licences, permits, consents or approvals under State law but expressly excludes a relevant environmental authorisation.

• Maximum lead‑in‑air condition: This is a defined element of a relevant environmental authorisation that specifies the maximum permissible air concentration of lead at location(s) in Port Pirie specified in that authorisation (s 3(1)). The Act’s restrictions on variation (s 4) and the modification of other State laws (s 5) are keyed to this specific condition type.

• Project and project completion date: “Project” is defined as the Company’s redevelopment of the plant to install enclosed bath smelting processing technology and associated works, replacing existing sinter technology (s 3(1)). The project completion date is a publication event: it is the date on which the Manufacturing Minister publishes notice in the Gazette that the Company has given a project completion notice (s 3(2)(c)).

• Temporal mechanisms and prescribed periods: The Act creates different time windows with different legal effects. The “commencement day” for s 4 is the day falling six months after the project completion date, or, if the Environment Protection Authority varies a maximum lead‑in‑air condition after the project completion date but before that six‑month day, the day on which that variation is made , whichever occurs first (s 4(6)). The “prescribed period” in s 4 commences on that commencement day and ends ten years later (s 4(6)). Separately, s 5(5) defines the “prescribed period” for s 5 as either ten years after the project completion date (if the Company gives a project completion notice) or four years after the commencement of the Act (if no project completion notice is given). These staggered definitions mean different parts of the Act take effect and expire on distinct calendars.

• Limits on administrative and legal powers: The core regulatory mechanism is a limitation on the EPA’s power to reduce a specified maximum condition (s 4(1)-(3)) and a statutory modification of other State laws and relevant authorisations so they do not apply to the extent they would reduce the specified maximum (s 5(1)-(2)). The Manufacturing Minister is given a gate‑keeping role in allowing exceptions (s 4(3)(a); s 5(3)) subject to prescribed consultation and consideration requirements (s 4(4); s 5(4)).

• Immunity: Section 6 provides that no act or omission undertaken by the Manufacturing Minister or other person engaged in administering the Act, with a view to exercising a power or function under the Act, gives rise to any liability against that person or the Crown. This is a statutory bar on civil claims for those officials and the Crown in respect of discretionary acts taken under the Act (s 6).

• Preservation of environmental duty: The Act expressly excludes from its s 4(2) prohibition any effect on requirements other than maximum lead‑in‑air conditions and preserves the Company’s obligation to take reasonable and practicable measures to prevent or minimise environmental harm (s 4(5)(a)-(b)). Thus the statutory protections as phrased do not displace other types of regulatory conditions or the general duty to prevent or minimise environmental harm.

These concepts are narrowly framed and interlock through the Act’s definitions, consultation requirements and time triggers. The Act is an instrument of targeted statutory modification rather than a general environmental regime.

The Act identifies a tight set of actors by name or role and places obligations, powers and protections that materially affect their legal position. The principal affected parties are:

• The Company: The Act expressly operates in relation to Nyrstar Port Pirie Pty Ltd ACN 008 046 428 and its successors and assigns (s 3(1)). The Company is both the beneficiary of the statutory protections against reductions in maximum lead‑in‑air conditions (s 5(1)) and the party with an express procedural duty to notify the Manufacturing Minister when commercial enclosed bath smelting operations start (s 3(2)(a)). The Company may also consent to variations that would reduce maximum lead‑in‑air conditions (s 4(3)(b); s 5(4)(a)) and thus can be the source of an exception.

• The Manufacturing Minister: Defined by reference to the Minister administering the Industries Development Act 1941 (s 3(1)), the Manufacturing Minister must receive and publish the project completion notice within specified time frames (s 3(2)(b)), must be consulted by the EPA before variations in certain windows (s 4(1)), may approve reductions in maximum lead‑in‑air conditions subject to consultation and consideration duties (s 4(3)-(4)), and may determine that specified State laws or authorisations should not be modified for the Company, but only with Company consent or after following consultation and consideration processes (s 5(3)-(4)). The Manufacturing Minister also benefits from statutory immunity in s 6 for acts or omissions in administering the Act.

• The Environment Protection Authority: The EPA’s administrative powers over relevant environmental authorisations are restrained by the Act. The EPA must consult the Manufacturing Minister and the Company prior to varying a maximum lead‑in‑air condition between the project completion date and the commencement day (s 4(1)). During the s 4 prescribed period the EPA may not reduce a maximum lead‑in‑air condition (s 4(2)), subject only to the Manufacturing Minister’s approval or the Company’s consent (s 4(3)). The Act thus changes the decision‑making environment and required processes for the EPA with respect to maximum lead‑in‑air conditions.

• The Minister administering the Environment Protection Act 1993: That Minister is a specific consultation party under the Manufacturing Minister’s pre‑approval duties and the s 5 determination process (s 4(4)(a)(ii); s 5(4)(b)(i)). Therefore the Act requires input from the environmental portfolio in the Manufacturing Minister’s decision‑making.

• Other State regulators and authorising bodies: The Act modifies the application of other State laws and relevant authorisations (defined in s 5(5)) so that any requirement that would reduce the specified maximum lead‑in‑air concentrations is taken not to apply to the Company during the prescribed period (s 5(1)). That alters the legal effect of instruments issued by other agencies to the extent they would reduce maximum lead‑in‑air conditions.

• The Port Pirie community and other interested parties: The Act explicitly requires the Manufacturing Minister to take into account the impact on the Port Pirie community when deciding whether to approve a reduction or to determine that other laws should not be modified (s 4(4)(b)(iv); s 5(4)(b)(ii)(D)). While the Act does not make the community a decision‑maker, it recognises the community as a relevant consideration in ministerial discretion and requires an invitation for written submissions in the s 4 and s 5 processes (s 4(4)(a); s 5(4)(b)(i)).

• Persons engaged in administration of the Act and the Crown: Those persons are shielded from civil liability for acts or omissions carried out with a view to exercising the Act’s powers or functions (s 6). That affects potential litigants seeking civil remedies against officials by removing a cause of action for acts and omissions covered by the immunity.

• Successors and assigns: The Company definition includes successors and assigns (s 3(1)), so the statutory protections and duties follow corporate succession, transfers and assignments that fall within that expression.

Notably the Act’s scope is limited: the protections apply only in relation to maximum lead‑in‑air conditions specified at locations in Port Pirie in a relevant environmental authorisation (s 3(1); s 5(1)). The Act does not purport to protect other operators or other types of environmental conditions. It also preserves the Company’s ongoing duty to take reasonable and practicable measures to prevent or minimise environmental harm (s 4(5)(b)), meaning other regulatory obligations continue to affect the Company.

The Act creates a set of discrete procedural duties, ministerial powers, and statutory rights or protections. These are primarily administrative duties on named actors and a statutory right for the Company not to have its maximum lead‑in‑air condition lowered by the State, subject to specified exceptions.

Company duties and rights

• Duty to notify: The Company must give notice to the Manufacturing Minister within 7 days after successfully commencing commercial operations of the enclosed bath smelting facility installed as part of the project (s 3(2)(a)). This is a mandatory, time‑limited notification duty that triggers other provisions of the Act, including the project completion date (s 3(2)(c)).

• Right to protection from reductions: The Company benefits from the statutory modification in s 5(1) which takes relevant State laws or authorisations that would reduce the maximum permissible air concentrations of lead at specified Port Pirie locations not to apply to the Company during the prescribed period. That is a statutory right in the sense that it removes the legal force of such requirements for the Company for the prescribed period (s 5(1)).

• Consent power: The Company may, by consenting, allow a reduction in a maximum lead‑in‑air condition (s 4(3)(b)). The Company’s consent is also a statutory prerequisite for the Manufacturing Minister to make a determination under s 5(3) that a particular law or authorisation should not be modified (s 5(4)(a)).

Manufacturing Minister duties and powers

• Duty to publish project completion notice: On receipt of the Company’s project completion notice the Manufacturing Minister must give notice of that receipt in the Gazette within 7 days (s 3(2)(b)). The date of Gazette publication is the project completion date (s 3(2)(c)), which triggers other time calculations.

• Consultation and decision responsibilities before approving a reduction: If the Manufacturing Minister is to approve a variation under s 4(3)(a), the Minister must consult with, and invite written submissions from, the Company and the Minister responsible for the Environment Protection Act 1993 (s 4(4)(a)). The Manufacturing Minister must take specified matters into account, including written submissions, recent medical and scientific advances relating to lead emissions, international standards relating to lead emissions, impacts on the Port Pirie community and the Company, and any other matter the Manufacturing Minister thinks fit (s 4(4)(b)(i)-(v)). This frames the scope of the Minister’s discretionary decision‑making.

• Power to determine exceptions to s 5 modifications: The Manufacturing Minister may determine that a particular law or authorisation should not be modified under s 5(1) or should be modified only in part, but may do so only with the Company’s consent or after the consultation and consideration process specified in s 5(4) (s 5(3)-(4)).

Environment Protection Authority duties and constraints

• Duty to consult: Between the project completion date and the commencement day the EPA may not vary a maximum lead‑in‑air condition in a way that would reduce the maximum without consulting the Manufacturing Minister and the Company (s 4(1)).

• Prohibition on varying maxima during the prescribed period: The EPA is barred from varying a maximum lead‑in‑air condition to reduce the maximum during the prescribed period (s 4(2)), unless either the Manufacturing Minister approves or the Company consents (s 4(3)).

Other State regulators and law‑makers

• Subject to statutory modification: Any State law or relevant authorisation that would have the effect of reducing the maximum lead‑in‑air concentrations at the Port Pirie locations specified in a relevant environmental authorisation is taken not to apply to the Company to that extent during the prescribed period (s 5(1)-(2)). That changes the legal effectiveness of their requirements as they affect the Company.

Immunity and rights to remedies

• Immunity for officials and Crown: s 6 removes any civil liability , statutory or common law, including negligence claims , against the Manufacturing Minister or other persons engaged in administering the Act, and the Crown, for acts or omissions done with a view to exercising or performing a power or function under the Act. That immunity narrows the set of civil remedies available against those officials for conduct taken under the Act.

Preservation of other obligations

• Environmental mitigation duty preserved: The Act disclaims any effect on non‑maximum lead‑in‑air conditions (s 4(5)(a)) and expressly preserves requirements that the Company take reasonable and practicable measures to prevent or minimise environmental harm resulting from its operations (s 4(5)(b)). Thus the Company retains duties to prevent or minimise harm, notwithstanding the statutory protections for maximum conditions.

Procedural rights of submission and consultation

• Invitation to provide written submissions: The Manufacturing Minister must invite written submissions,within a reasonable period specified by the Minister,from the Company and the Minister responsible for the Environment Protection Act 1993 before approving a variation (s 4(4)(a)); a similar invitation and consultation requirement applies before making determinations under s 5(3) in the circumstances where the Manufacturing Minister proceeds without the Company’s consent (s 5(4)(b)(i)). The Act therefore creates procedural rights to be heard for specified actors.

These duties and rights are procedural and protective rather than criminal. The Act reallocates decision‑making authority and legal effect in circumscribed ways, while preserving other environmental duties.

The Act does not create express criminal offences, fines or a separate statutory enforcement regime in the text supplied. Its primary enforcement mechanisms are structural and administrative: it constrains the legal powers of decision‑makers and alters the application of State laws. The enforcement consequences therefore arise from how those constraints operate within existing administrative and legal systems.

Administrative constraints and legal effect

• Prohibition on EPA action: The Act expressly forbids the Environment Protection Authority from varying a maximum lead‑in‑air condition to reduce the maximum during the prescribed period, subject to the exceptions in s 4(3) (s 4(2)). That prohibition is backed by statute: non‑compliance by the EPA would be a failure to observe a statutory constraint. The Act itself does not set out a penalty for an EPA official acting unlawfully, but a statutory prohibition creates a basis for judicial review or other remedies under administrative law (the Act does not specify those remedies, but the prohibition is a legal limit that could be enforced by the courts).

• Modification of other laws: Section 5 modifies the law of the State so that any State law or relevant authorisation that would reduce the maximum lead‑in‑air concentration is taken not to apply to the Company during the prescribed period (s 5(1)). That is not an enforcement mechanism in the form of sanctioning. Rather, it operates by removing the legal force of such requirements as they apply to the Company. The practical enforcement effect is that a regulator cannot rely on those requirements, to the extent they would reduce the maximum, against the Company during the prescribed period.

Absence of express penalties

• No express criminal or civil penalties in the Act: The Act contains no provisions creating offences, pecuniary penalties, compliance notices, or enforcement processes such as infringement notices. The only civil‑law‑related provision is a statutory immunity for the Manufacturing Minister and other persons engaged in administering the Act from any liability arising from acts or omissions done with a view to exercising powers or functions under the Act (s 6). That immunity reduces the risk of civil enforcement against those officials but does not themselves create penalties.

Practical routes to enforce or challenge

• Administrative review and judicial remedies: Because the Act imposes statutory duties and constraints (for example, consultation requirements (s 4(1); s 4(4)(a); s 5(4)(b)(i)) and the prohibition on EPA varying maximum conditions (s 4(2))), affected parties could seek remedies available under general administrative law for breaches of statutory duty or procedural fairness, or seek declaratory relief that an action is inconsistent with the Act. The Act contains no procedural bar to such challenges in the text provided, but s 6 removes liability for civil claims against responsible ministers and officials for acts or omissions done with a view to exercising powers under the Act (s 6). The Act does not itself describe judicial review procedures, standing or costs.

Interaction with existing enforcement regimes

• Continued applicability of other enforcement powers where not excluded: The Act explicitly preserves other requirements and duties, including the Company’s requirement to take reasonable and practicable measures to prevent or minimise environmental harm (s 4(5)(b)). That suggests that other enforcement mechanisms under the Environment Protection Act 1993 and other laws remain available to address environmental harm to the extent they are not precluded by s 5(1). The Act modifies only those requirements that would reduce maximum lead‑in‑air concentrations specified in the Company’s relevant environmental authorisation (s 5(1)).

Summary of enforcement posture

• The Act enforces its policy primarily by constraining decision‑makers and removing the operation of certain State requirements, rather than through new criminal or civil sanctions. Compliance is achieved through adherence to the new statutory limits on the EPA and other State laws, the Manufacturing Minister’s consultative and decision‑making duties, and the Company’s notification duty. The immunity provision narrows the scope of civil liability for officials carrying out actions in administering the Act (s 6). The practical enforcement and challenge landscape will therefore be shaped by administrative law remedies and the existing enforcement powers in other statutes , except where those powers are statutorily displaced by s 5(1) for the Company during the prescribed period.

The Act is expressly designed to modify the application of existing State laws and authorisations in relation to maximum lead‑in‑air conditions for the Company at Port Pirie. The text sets out both the scope of modification and the consultation-based gate for restoring the operation of other laws.

Modification of State law and authorisations

• Statutory modification: Section 5(1) modifies the law of the State so that any requirement under a State law or a relevant authorisation that would have the effect of reducing the maximum permissible air concentrations of lead at the locations in Port Pirie specified in a relevant environmental authorisation is taken not to apply to the Company during the prescribed period. The source text expressly states this modification applies whether the relevant requirement was imposed before or after the Act commenced (s 5(2)). Therefore the Act operates prospectively and retrospectively (in legal effect) in relation to the timing of those requirements.

• Scope and limitation: The effect of s 5 is tightly circumscribed. It applies only to requirements that would have the effect of reducing maximum permissible air concentrations of lead in the locations specified in a relevant environmental authorisation (s 5(1)). It does not apply to other requirements or authorisations unrelated to the maximum lead‑in‑air condition. Moreover, “relevant authorisation” in s 5(5) is defined broadly to include licences, permits, consents or approvals under State law but explicitly excludes a relevant environmental authorisation. A “relevant environmental authorisation” is separately defined in s 3(1) as an authorisation under the Environment Protection Act 1993 applying to the Company’s operations. Thus the Act differentiates between instruments under the Environment Protection Act 1993 (the relevant environmental authorisation) and other State authorisations.

Role of the Environment Protection Authority

• Altered decision‑making: The Act places a specific statutory limitation on the EPA’s ability to vary maximum lead‑in‑air conditions (s 4(2)). During the prescribed period the EPA may not make a variation that reduces a maximum lead‑in‑air condition (s 4(2)), and between the project completion date and the commencement day the EPA must consult with the Manufacturing Minister and the Company before varying a maximum lead‑in‑air condition in a way that would reduce the specified maximum (s 4(1)). These provisions directly alter how the EPA exercises functions under the Environment Protection Act 1993 in relation to the Company’s relevant environmental authorisation.

Ministerial coordination and consultation with environmental portfolio

• Input from environment minister: The Manufacturing Minister is required to invite written submissions from the Minister to whom the administration of the Environment Protection Act 1993 is committed before approving a variation under s 4(3)(a) (s 4(4)(a)(ii)). Similarly, if the Manufacturing Minister contemplates making a determination under s 5(3) refusing the statutory modification for a particular law or authorisation without the Company’s consent, the Minister must consult and invite submissions from the Company and the relevant Minister of the Act under which the particular law or authorisation is imposed (s 5(4)(b)(i)). These cross‑portfolio consultation requirements insert ministerial coordination before exceptions are granted.

Preservation of environmental duties and concurrent regimes

• Non‑displacement of other obligations: Section 4(5)(b) states nothing in s 4(2) affects any requirement for the Company to take reasonable and practicable measures to prevent or minimise environmental harm that may result from its operations. That indicates the Act does not displace general environmental duties arising elsewhere; it displaces only those requirements of other laws or authorisations that would have the effect of reducing the specified maximum lead‑in‑air concentration (s 5(1)). Consequently, enforcement and compliance powers under other statutes remain relevant except where s 5(1) operates to remove them in respect of reducing maximums.

Temporal interaction and overlapping periods

• Different prescribed periods: The Act specifies different temporal regimes for s 4 and s 5. The commencement day and prescribed period for s 4 are defined in s 4(6) and run from the commencement day to ten years after that day. The s 5 prescribed period starts on commencement of the Act and ends either ten years after the project completion date (if the project completion notice is given) or four years after commencement of the Act if no project completion notice is given (s 5(5)). The effect is that the timeframe during which the EPA is constrained (s 4) and the timeframe during which other State laws are modified for the Company (s 5) may overlap or run on different calendars, depending on the project completion notice and any EPA variation after the project completion date. Agencies must therefore track multiple statutory timelines when assessing which requirements apply.

Effect on existing and future authorisations

• Authorisations before and after the Act: Section 5(2) explicitly states the modification under s 5(1) applies regardless of whether the relevant requirement was imposed before or after the Act commenced. Thus regulators and drafters of future authorisations must account for the Act’s protective effect in relation to maximum lead‑in‑air conditions for the Company during the prescribed period. Conversely, where the Manufacturing Minister exercises a s 5(3) determination not to modify a particular law or authorisation, that determination can restore the application of that law or authorisation to the Company, subject to the consent or consultation processes set out in s 5(4).

Immunity’s interaction with liability regimes

• Removal of civil liability for officials: Section 6 provides immunity against civil liability for the Manufacturing Minister and other persons engaged in administering the Act for acts or omissions done with a view to exercising or performing a power or function under the Act. That immunity interacts with other liability regimes by removing a cause of action against those officials and the Crown for conduct within the immunity’s scope. The Act does not, however, remove enforcement or liability for the Company itself under other laws where those laws continue to apply (for example, requirements to prevent or minimise environmental harm remain (s 4(5)(b))).

In sum, the Act operates as a targeted modification to the operation of the Environment Protection Act 1993 and other State laws as they affect the Company’s maximum lead‑in‑air conditions. It inserts ministerial coordination and consultation into the matrix of decisions that might reduce those maximums and creates a statutory shield for those decisions. Its temporal structure and narrow subject matter mean its interaction with other laws is precise and confined to the reduction of specified maximum lead‑in‑air conditions.

The source supplied contains only the principal Act’s legislative history and records no subsequent amendments. The legislative history in the text shows:

• Principal Act: Port Pirie Smelting Facility (Lead‑In‑Air Concentrations) Act 2013, No. 38, assented 19 September 2013, with commencement recorded as 1 May 2014 and Gazette notice reference (Gazette 1.5.2014 p1569).

No schedules, transitional amendments or later amending Acts are recorded in the supplied text. There is no expressed amendment to the Act’s sections or changes to definitions in the provided material. The Act’s temporal provisions incorporate later events (for example, the project completion date and any EPA variation after that date) into the operation and expiry of the “prescribed periods” (s 4(6), s 5(5)), but those are operational mechanisms within the original text rather than subsequent legislative amendments.

Implications of the absence of recorded amendments in the supplied source

• The statutory regime as printed in the provided text is the operative text that sets out the protective measures, consultation duties and immunity provisions. Users of the Act should treat the text as the current source for the legal rules described in this note, subject to the usual caveat that subsequent amendments, regulations or judicial interpretation may alter application if not reflected in the provided material.

• The Acts index or the official legislation website (the text notes the Index of South Australian Statutes or www.legislation.sa.gov.au for further information) is flagged for those seeking any subordinate legislation or later changes; however, the supplied source itself records only the principal Act’s passage and commencement.

• Because the Act’s operation depends on events that may occur post‑commencement (notably, the project completion notice and any EPA variation), the effective calendar for some protective measures depends on factual developments anticipated by the Act rather than on later legislative amendment. The Act’s design embeds contingent triggers rather than requiring later amending legislation to activate the core temporal protections.

If further amendments have been made after the text furnished, those are not recorded here. Readers and practitioners should consult the official consolidated legislative database noted in the Act’s legislative history for any post‑2013 alterations, but the supplied source contains only the original principal Act and its commencement information.

The supplied text contains no record of litigation involving the Act. The legislative history provided lists only the principal Act’s assent and commencement dates; it does not record any cases, judicial decisions, or disputes that interpret, apply, or challenge the Act. Therefore, within the material supplied:

• There is no judicial construction or precedent recorded that interprets the Act’s consultation duties, the scope of the manufacturing minister’s discretion, the meaning of “maximum lead‑in‑air condition”, the interaction of s 5 with other statutory schemes, or the application of the immunity in s 6.

• The Act’s silence in the supplied material on litigation means there is no primary‑text authority in this document that clarifies potential ambiguities, such as the precise scope of the immunity in s 6, the thresholds for “reasonable and practicable measures” preserved by s 4(5)(b), or administrative law standards applicable to any consultation or decision‑making obligations imposed on the Manufacturing Minister or the EPA.

Practical implications of an absence of recorded litigation

• Without recorded judicial guidance in the supplied text, interpretation of ambiguous elements of the Act would fall to courts if disputes arise. The Act’s procedural requirements (for consultation and invitation to make written submissions) and its substantive modifications of State law create factual settings that could give rise to challenges, for example by third parties affected by a ministerial approval or a determination under s 5(3). However, the supplied text includes no judicial responses to those prospective disputes.

• The immunity provision in s 6 removes civil liability for acts or omissions undertaken by the Manufacturing Minister or persons engaged in administering the Act with a view to exercising or performing a power or function under the Act. The presence of this immunity may reduce the pool of viable civil claims against those officials, but the supplied source does not show how courts have applied or defined the scope of that immunity in practice.

• The absence of litigation history in the supplied material leaves unresolved practical questions for stakeholders (such as third parties considering judicial review or challenge) about procedural rights, standing and the judicial approach to statutory consultative duties and ministerial discretions under this Act, because those questions are not answered in the Act’s text and no courts are recorded as having addressed them in the supplied material.

For readers seeking case law or judicial developments, the Act itself refers users to the Index of South Australian Statutes or the official legislation website for “further information relating to the Act and subordinate legislation made under the Act”, but no litigational record is present in the provided source. Any litigation history post‑dating the supplied text is outside the scope of this material.

The Act’s brevity masks several technical and practical pitfalls that arise from its drafting choices, temporal structure, and the narrowness of its defined concepts. The following are concrete, source‑grounded points to watch:

Timing triggers and multiple prescribed periods

• Different definitions and deadlines: The Act uses different “prescribed period” constructs for s 4 and s 5 (s 4(6) and s 5(5)). Section 4’s “commencement day” can be the day that falls six months after the project completion date, or an earlier day if the EPA varies a maximum lead‑in‑air condition after the project completion date but before that six‑month date , whichever is first (s 4(6)). Section 4’s prescribed period runs from that commencement day to ten years later (s 4(6)). By contrast, s 5’s prescribed period starts on commencement of the Act and ends ten years after the project completion date if a project completion notice is given, or four years after commencement of the Act if no project completion notice is given (s 5(5)). Practitioners must track at least three calendar events: the Act’s commencement, the project completion date (Gazette publication), and any EPA variation that may occur in the six months after project completion. Misreading which “prescribed period” applies in a given situation is a likely source of error.

Dependence on Gazette publication

• Project completion date defined by Gazette notice: The project completion date is the date on which the Manufacturing Minister publishes notice of receipt of the project completion notice in the Gazette (s 3(2)(b)-(c)). That makes the Act’s key date a ministerial publication step. If the Manufacturing Minister fails to publish within the 7‑day statutory deadline or publishes late, the calculation of temporal triggers (such as the commencement day and prescribed periods) could be affected. The Act does not specify consequences for late publication, other than the statutory requirement itself, so parties should record and preserve proof of publication timing.

Narrow scope of statutory protection

• Limited to maximum lead‑in‑air conditions at specified Port Pirie locations: The Act’s protective modifications apply only to “any requirement … that would have the effect of reducing the maximum permissible air concentrations of lead at a location or locations in Port Pirie specified in a condition of a relevant environmental authorisation” (s 5(1)). That means other environmental requirements, authorisations affecting other pollutants, or requirements applicable to non‑specified locations are not covered. Users should avoid over‑reading the Act as protecting all aspects of the Company’s environmental regulation.

Distinction between relevant environmental authorisation and relevant authorisation

• Different definitions create drafting traps: s 3(1) defines “relevant environmental authorisation” as an authorisation under the Environment Protection Act 1993 applying to the Company. s 5(5) defines “relevant authorisation” more widely (licence, authorisation, permit, consent or approval under a law of the State) but expressly excludes a relevant environmental authorisation. That bifurcation means regulators and advisers must read the two concepts carefully when determining which instruments the Act modifies and which remain in force.

Ministerial discretion and the Company’s consent

• Company can block modifications or grant exceptions: Under s 4(3)(b) the Company’s consent permits the EPA to vary a maximum lead‑in‑air condition during the prescribed period. Under s 5(4)(a) the Manufacturing Minister may make a determination that a particular law should not be modified, but only with the Company’s consent, or alternatively only after the consultation and considerations set out in s 5(4)(b) if the Company does not consent. The Company therefore occupies a decisive position: it can either agree to permit reductions or exercise a veto in some contexts. That shifts bargaining power and could be unexpected for other stakeholders.

Immunity and access to remedies

• Statutory immunity for officials: s 6 states that no act or omission by the Manufacturing Minister or any other person engaged in administering the Act with a view to exercising or performing a power or function under the Act gives rise to any liability against those persons or the Crown. This removes an avenue for civil claims against officials exercising powers under the Act. Parties considering challenging ministerial action should note the immunity’s scope: it is broad as to civil liability for acts or omissions done with a view to exercising powers under the Act, but the Act does not expressly address whether judicial review of the lawfulness of decisions remains available. The absence of recorded litigation in the supplied text makes judicial interpretation of this immunity uncertain within the source material.

Consultation but discretionary considerations

• “Any other matter the Manufacturing Minister thinks fit”: The consultation steps in s 4(4)(a) and s 5(4)(b)(i) require inviting written submissions and taking into account enumerated matters, including “any other matter the Manufacturing Minister thinks fit” (s 4(4)(b)(v); s 5(4)(b)(ii)(E)). This gives the Manufacturing Minister broad discretion in decision‑making, which can be a source of unpredictability for stakeholders seeking a specified decision standard.

Preserved obligations to prevent or minimise environmental harm

• Statutory protection does not displace mitigation duties: Section 4(5)(b) explicitly states that nothing in the prohibition on varying maximum lead‑in‑air conditions affects any requirement for the Company to take reasonable and practicable measures to prevent or minimise environmental harm. Practitioners should not assume that the Act exempts the Company from environmental mitigation obligations; those duties survive and can be enforced under other laws that are not modified by s 5(1).

Retrospective effect on certain requirements

• Applies to requirements imposed before or after the Act: Section 5(2) makes the s 5 modification apply to relevant requirements regardless of whether they were imposed before or after the Act commenced. That can have retroactive consequences for pre‑existing instruments that might have reduced maximum lead‑in‑air conditions; parties must therefore re‑examine past authorisations to determine current applicability.

Who the Act does not protect

• Only applies to the named Company: The Act expressly names a single corporate entity and includes successors and assigns (s 3(1)). Other operators or parties that might be affected by lead‑in‑air standards are outside the Act’s protective scope. That focuses benefits narrowly and is not a generic industry exemption.

These are practical drafting and operational “gotchas” that arise directly from the Act’s text. They indicate where careful calendaring, precise identification of affected instruments, and attention to ministerial processes are required to avoid missteps.

Compliance under this Act is primarily administrative: it requires timely notices, adherence to consultation processes, and awareness of the statutory timelines and limitations. The core compliance tasks for the principal actors named in the Act are as follows.

For the Company (Nyrstar Port Pirie Pty Ltd and successors and assigns)

• Project completion notice: The Company must give notice to the Manufacturing Minister of the day on which commercial operations of the enclosed bath smelting facility (installed as part of the project) successfully commenced not more than 7 days after that day (s 3(2)(a)). Compliance requires preparing and serving that notice within the 7‑day window and retaining evidence of the date of service. Failure to give the notice may affect the timing of the project completion date and the operation of the Act’s prescribed periods (s 3(2)(c)).

• Consent processes: If the Company wishes to permit a reduction in the maximum lead‑in‑air condition during the prescribed period, the Company may provide consent under s 4(3)(b). The Company’s consent is also a statutorily recognised precondition under s 5(4)(a) to the Manufacturing Minister making a determination that a particular law or authorisation should not be modified. The Company should document any consent carefully, specifying scope and timing, and keep records of communications with the EPA and the Manufacturing Minister.

• Continuing environmental mitigation: Even where the Act protects the Company against reductions in maximum lead‑in‑air conditions, the Company remains subject to requirements to take reasonable and practicable measures to prevent or minimise environmental harm arising from its operations (s 4(5)(b)). The Company should continue to implement and document environmental management, monitoring and mitigation measures in line with existing relevant environmental authorisations and statutory duties that remain in force.

For the Manufacturing Minister

• Timely Gazette publication: On receipt of the Company’s project completion notice the Manufacturing Minister must publish notice of that receipt in the Gazette within 7 days (s 3(2)(b)). The Manufacturing Minister should ensure Gazette publication is effected promptly and maintain records of the date of publication, as the project completion date is the date of Gazette publication (s 3(2)(c)), which triggers other statutory timings.

• Consultation and invitation for written submissions: Before approving a variation under s 4(3)(a), the Manufacturing Minister must consult with and invite written submissions from the Company and the Minister responsible for the Environment Protection Act 1993, within a reasonable period specified by the Manufacturing Minister (s 4(4)(a)). The Manufacturing Minister must take into account enumerated matters (s 4(4)(b)). Similarly, before making a s 5(3) determination without the Company’s consent, the Manufacturing Minister must consult and invite written submissions from the Company and, if relevant, the Minister administering the Act under which the law or authorisation is imposed (s 5(4)(b)(i)), and take into account specified matters (s 5(4)(b)(ii)). The Manufacturing Minister should set reasonable, publicly defensible timelines for submissions, record consultation steps, and document the reasoning showing consideration of the listed factors.

• Determinations and issuing notices: If the Manufacturing Minister determines under s 5(3) that a particular law or authorisation should not be modified, or should only be modified as specified, the determination must be given in writing to the Company (s 5(3)). The Manufacturing Minister must ensure that determinations are properly recorded, communicated, and that statutory requirements for consent or consultation and consideration have been met before issuing them (s 5(4)).

For the Environment Protection Authority

• Consultation obligations: Between the project completion date and the commencement day the EPA must consult with the Manufacturing Minister and the Company before making a variation that would reduce a maximum lead‑in‑air condition (s 4(1)). The EPA should schedule internal decision timelines to permit this consultation and document the consultation process, including dates and the content of any responses.

• Compliance with prohibition on reductions: During the prescribed period the EPA may not vary a maximum lead‑in‑air condition to reduce the maximum (s 4(2)) unless the Manufacturing Minister approves or the Company consents (s 4(3)). The EPA must check whether the prescribed period applies and verify whether any allowed exceptions exist before proceeding with a variation.

For other State regulators and authorising bodies

• Assess effect of instruments: Regulators and issuers of licences, permits or approvals must assess whether any proposed requirement would have the effect of reducing the maximum permissible air concentrations of lead at Port Pirie locations specified in a relevant environmental authorisation. If so, such requirements are statutorily taken not to apply to the Company during the s 5 prescribed period (s 5(1)), unless the Manufacturing Minister exercises a s 5(3) determination that the law should not be so modified, subject to s 5(4).

• Liaise with Manufacturing Minister where appropriate: If a regulator contemplates instruments that may be affected by s 5, they should coordinate with the Manufacturing Minister’s office because the Manufacturing Minister can determine that a particular law or authorisation should not be modified for the Company, but only with consent or after specified consultation and consideration (s 5(3)-(4)). This coordination prevents unintended conflicts and ensures regulatory intentions align with statutory constraints.

For interested members of the Port Pirie community and other stakeholders

• Participation in consultations: The Manufacturing Minister must invite written submissions (within a reasonable period specified by the Minister) from the Company and the Minister administering the Environment Protection Act 1993 in the s 4 approval process (s 4(4)(a)). The s 5 process requires consultation and invitation of written submissions from specified parties when the Manufacturing Minister makes determinations without Company consent (s 5(4)(b)(i)). While the Act prescribes the parties who must be invited to submit, it also requires the Manufacturing Minister to take into account the impact on the Port Pirie community (s 4(4)(b)(iv); s 5(4)(b)(ii)(D)). Community actors should endeavour to engage during the specified submission windows and prepare written material addressing the listed factors.

Record‑keeping, timing and proof

• Documentation is central: Because the project completion date, commencement day and prescribed periods determine legal effect, all parties should keep contemporaneous records of notices, Gazette publications, consultation invitations, received submissions, and ministerial determinations. These records will be necessary to demonstrate compliance with the Act’s procedural duties and to establish the applicability of s 4 and s 5 protections at any given time.

Legal advice and risk management

• Seek legal clarification where necessary: Where there is uncertainty about whether a particular condition reduces a “maximum lead‑in‑air condition” (s 3(1)) or whether a proposed instrument is a “relevant authorisation” (s 5(5)), regulated parties should obtain legal advice to determine whether the Act modifies the instrument’s application. The Act’s definitions and its temporal mechanics mean fact‑sensitive assessments will be common.

In short, compliance under the Act is about fulfilling the notification and consultation duties, tracking the Act’s temporal triggers, documenting consents and ministerial decisions, and maintaining environmental mitigation measures that remain in force. Careful record‑keeping and interagency coordination are the practical necessities the Act’s text prescribes.
