Amran Cement Plant

The Amran Cement Plant (ACP) is currently undergoing expansion works that will increase its annual production capacity of Portland cement to more than 1,600,000 tons. At the time of this study, construction works associated with the new production line had been either commissioned or partially completed. The study was funded by the United States Agency for International development (USAID) through the Partners for Health Reform plus (PHRplus) project following requests by the Ministry of Water and Environment, the Environmental Protection Agency as well as the Management of ACP that have expressed commitment towards implementing the plans recommended in the study. The scope of work implemented in the preparation of the EA study included the definition of existing legal and administrative framework, description of the existing and proposed expansion facilities, definition of baseline environmental conditions, identification and analysis of potential environmental impacts, analysis of potential emission control alternatives, and the development of an environmental management plan with mitigation, monitoring, as well as capacity building and institutional strengthening requirements.

The EA showed that ACP provides a significant positive socio-economic impact related to the potential increase in job opportunities for locals as well as providing a product that is much needed to meet the demand for the construction and development activities that are occurring on the national scale. In contrast, several potential adverse impacts can negatively affect the environment particularly those associated with emissions, effluent discharge, and waste generation. In the absence of control measures, the assessment of current and projected emissions indicated that ACP operations may result in serious exposure to particulate matter for nearby receptors and the plant workforce. Other indicators that can potentially be impacted include traffic, noise, surface and ground water quality, soil quality, terrestrial biodiversity, resource use, health and safety, landscape and visual intrusion. As such, the adoption of proper environmental management plans will likely enhance the sustainability of cement production and the expected benefits from ACP operations.

Undoubtedly, potential adverse impacts associated with the operations at ACP can be minimized by relying on effective mitigation, monitoring, and training plans to support management decisions. In the context of this assessment, a mitigation plan proposed several impact-mitigation or control measures that will earn ACP more acceptability, by eliminating or reducing to the extent possible potential adverse impacts. Similarly, a monitoring plan of impact indicators outlined above as well as operations indicators was developed.

The plan defines for each indicator the monitoring means and methodology, the parameters to be monitored, as well as the monitoring location and frequency. Capacity building, training, and awareness components were also defined to assist ACP in the implementation process of environmental management plans. The analysis of alternative compared the adoption of a Best Available Technology (BAT) or end-of-pipe technology for reducing particulate matter (PM) emissions to the “do nothing” or “no control” scenario. Evidently, the implementation and proper operation of a BAT will minimize emissions and will result in an acceptable impact on air quality. The advantages and disadvantages of the two most commonly used emissions control BATs, namely Fabric Filters (FFs) and Electro Static Precipitators (ESPs), were also examined in the context of ACP. While slightly more expensive, FFs appear to be more appropriate for ACP. Last but not least, two proposals set forth for constructing a bag house system were examined. Information and data needed to refine the examination were defined.
