Proposed project location Mombasa Cement Limited Vipingo factory is located in Kilifi County, Kikambala Division, Takaungu /Mavueni Location at Vipingo off Mombasa-Kilifi Road on two parcels of land namely MN/III/291/2 and MN/III/4391 the GPS coordinates of the proposed expansion are UTM X-0593567 & UTM Y- 9586780. The project components The proposed expansion will involve construction of two new cement factories for the manufacture of clinker and cement. The components of the expansion will include construction of a boundary wall to enclose each new cement factory, limestone crusher, limestone pre- blending stockpile, additive storages, raw material hoppers, raw mill building & bag house, Compiled by Philip M. Omenge, J. Morumbasi Mong‘oni, & Dr. George Eshiamwta, EIA/EA Lead Experts 2015 Page i Mombasa Cement Ltd Vipingo EIA Study Report for Proposed expansion blending silo, kiln feed, preheater tower, rotary kiln, clinker cooler building, clinker transport conveyer, clinker storage, gypsum storage, pozzolana storage, coal stockpile, coal mill building, cement mill hoppers, cement Mill building, cement silos, cement packing plant, cement loading for dispatch, clinker dispatch station, main sub-station, central control room, laboratories, engineering offices, stores, weighbridges, dispatch offices, water reservoirs and water treatment plant. Project cost The proposed expansion is estimated to cost KSH 7, 360,000,000.00 (seven billion, three hundred and six million Kenya Shillings only. Raw materials to be used MCL will grind, mix and burn in a kiln coral limestone, shale and iron ore in a clinkerization process to produce clinker. Coal will be the source of energy in firing the kiln during clinkerization. To produce cement, MCL will mix and grind in a cement mill clinker, pozzolana and gypsum. Sources of raw material The limestone that will be used in clinker production will be sourced from existing limestone deposits that MCL is currently extracting for use in clinker and cement production for the existing plant. MCL has an EIA licence for extracting these limestone deposits namely application reference number EIA/217 (registration number 0000337) and application reference number CP/PR.0495 (registration number 0007709). Shale that will be used in clinker production will be sourced from existing shale quarry owned by MCL at Vyambani within Kilifi County. MCL has an EIA licence for the shale quarry application reference number CP/PR/0682 (registration number 0007707). Iron ore and pozzolana will be bought from people who have their own quarries of pozzolana and iron ore while gypsum will be imported as currently is the practice. Envisaged positive impacts Potential positive impacts likely to result from the proposed expansion may include:- Compiled by Philip M. Omenge, J. Morumbasi Mong‘oni, & Dr. George Eshiamwta, EIA/EA Lead Experts 2015 Page ii Mombasa Cement Ltd Vipingo EIA Study Report for Proposed expansion Increased exploitation of minerals used in cement production Increase in cement production in Kenya Reduction in cement imports Increase in Cement exports Employment opportunities Support of local businesses Increased revenue to government Potential negative impacts Increased gaseous emissions Increased dust emissions Increased noise disturbance Occupational injuries and or accidents Waste (liquid and solid) related pollution Negative impacts on local fauna Negative impacts on local flora Negative impacts on avifauna Proposed mitigation measures Emission of sulfur dioxide from clinker production process can be mitigated by using the following technologies; inherent scrubbing, oxygen control (increase), fuel substitution (lower total sulfur), raw material substitution (lower sulfide sulfur), raw material alkali/sulfur balance, in-line raw mill, peheater upper stage hydrated lime injection, calcined feed recirculation, cement kiln dust internal scrubber, preheater upper stage trona injection and calcium-based internal scrubber. Emission of Nitrogen Oxides from clinker production process can be mitigated by using the following technologies; oxygen control (decrease), indirect firing, low-NOX burner, mid-kiln firing, process improvements, process control improvements, low-NOX Compiled by Philip M. Omenge, J. Morumbasi Mong‘oni, & Dr. George Eshiamwta, EIA/EA Lead Experts 2015 Page iii Mombasa Cement Ltd Vipingo EIA Study Report for Proposed expansion calciner, staged combustion, semi-direct firing, mixing air fan and cement kiln dust insufflation. Emission of carbon monoxide from clinker production process may be mitigated using the following technologies; good combustion practice, excess air (increase), raw material substitution, pyroprocessing system design and mixing air fan. Emission of carbon dioxide from clinker production process can be controlled using the following technologies; improved thermal efficiency, clinker substitution, improved electrical efficiency, raw material substitution and mineralizers. Emission of ammonia from clinker production process can be mitigated through raw material substitution and tailpipe scrubber technologies. Dust emission from clinker and cement grinding can be mitigated by use of bag filter technology and electrostatic precipitators‘ technology. Fugitive dust from clinker and cement production can be mitigated by application of dust suppressant such as water sprinkling and enforcement of the use of appropriate personal protective equipment such as dust masks. Noise can be mitigated by developing and implementation of a comprehensive noise management programme that include assessing the risks, protecting employees, maintaining and equipment use, raining and sensitising of workers, health surveillance and work reviews. Measures that can be put in place to mitigate solid waste generation may include appropriate management practices and deliberate innervations aimed at minimization of waste generation. Impacts on flora, fauna and avifauna can be mitigated by continuous planting of trees and other vegetation in and around the cement plant open areas and undertaking comprehensive quarry rehabilitation in all mined areas. Traffic related negative impacts can be mitigated by developing a comprehensive traffic marshal plan. Compiled by Philip M. Omenge, J. Morumbasi

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Kogyae Strict Nature Reserve, the only one in Ghana, was established to promote scientific re- search, particularly on how nature revitalizes itself after major disasters, and also to check the southward drift of the savannah grassland. This study presents the first comprehensive inventory of species composition and diversity of insects of the Reserve. Insects were surveyed between September 2011 and June 2012 to capture the end of the rainy season, the dry season and the peak of the wet season. Samples were taken from two sites within the Reserve, Dagomba and Oku using various sampling techniques including pitfall traps, malaise traps and sweep nets. Insect com- munities were characterized in terms of, 1) species richness estimators, 2) species richness, 3) Shannon-Weiner Index of Diversity, 4) Pielou’s evenness and 5) Bray-Curtis similarity.

The biological diversity on these islands is unknown and so a rapid assessment was conducted in January 2014 as part as a region wide assessment to determine the butterfly diversity on two of these islands, Biobio and Agbasiagba. Diversity indices were computed for both islands using the Shannon-Weiner index, Margalef’s index for richness and Whittaker’s index for comparison of diversity between the two islands. A total of eight hundred and eighty-one (881) individual butterflies representing forty-five (45) species belonging to eight (8) families were recorded during the study. Thirty-nine (39) species of butterflies were recorded on Biobio island whiles twenty-eight (28) species were recorded on Agbasiagba. This was expected as the larger islands are expected to support more species than smaller ones, with Biobio island being relatively bigger than Agbasiagba. The shared species of butterflies on both islands were twenty-two (22) representing 48.9% of the total species accumulated. Indicator species like Junonia oenone, Danaus chrysippus and Papilio demodocus were also recorded indicating the degraded floral quality of the Islands.
