This report section details the legislative and technical compliance requirements for the life extension (Life-ex) project at the Hendrina Power Station. It covers safety regulations for pressure equipment and boiler structures, emission limits under the South African Air Quality Act, and a comprehensive list of mandatory Eskom and international standards for turbine, electrical, and common plant areas. The document identifies specific areas of non-compliance, particularly regarding emissions, transformer maintenance, and environmental management of waste and water systems.

• Hendrina Power Station is currently compliant with 'existing plant' emission limits but fails to meet the more stringent 'new plant' limits for nitrogen oxides (NOx) and sulphur oxides (SOx). To achieve compliance with the South African Air Quality Act, the station requires a low-NOx burner retrofit and technology to reduce SOx emissions, such as Flue Gas Desulphurization.
• The station's auxiliary transformers are not meeting numerous inspection requirements specified in Eskom standard 240-56358993, specifically regarding moisture ingress and leaks that cause environmental contamination. Consequently, most transformers now require expensive replacement or refurbishment.
• The station's earthing system is not in accordance with established Eskom standards, as current maintenance and inspections of the ground bed and generation unit links are only performed every five years. The report recommends upgrading the entire system to comply with Eskom standard 474-085, which requires individual earth mats for each unit and specific operational areas with a resistance of no less than 0.14 Ω to ground.
• Several ZORC MV motor surge suppressors located in the PILCSWA / XLPE cable link box have exploded, which the report classifies as both an equipment safety violation and a personnel safety violation due to the oil filling of the ZORCS.
• Hendrina Power Station does not currently meet the minimum requirements for Zero Liquid Effluent Discharge (ZLED) status, although projects to achieve this are listed on the LOPP for execution.
• The report identifies several critical environmental and civil infrastructure failures that require mitigation under the National Environmental Management Act, including the need to line the maturation pond, the 7 Year Dam, and two Raw Water Reservoirs, as well as repairing cracks in Clarifier Tank walls and refurbishing ash dump channels.
• Under the Pressure Equipment Regulation (PER) of the Occupational Health and Safety Act 1993, the station's boiler is classified as a hazard category IV, while most piping is category III. This requires that all repairs, modifications, and designs be verified by an Approved Inspection Authority (AIA) and certified by the modifier.
