Ua hōʻike ʻia ʻo Fabricated Geomembrane Institute (FGI) ma ke Kulanui o Illinois ma Urbana-Champaign i ʻelua Fabricated Geomembrane Engineering Innovation Awards i ka wā o kāna hui lālā biennial ma Houston, Texas, ma Feb. 12, 2019, ma ka 2019 Geosynthetics Conference.ʻO ka makana ʻelua, ʻo ka 2019 Engineering Innovation Award no Outstanding Fabricated Geomembrane Project, ua hāʻawi ʻia iā Hull & Associates Inc. no ka papahana Montour Ash Landfill-Contact Water Basin.

ʻO nā koena hoʻopau ahi (CCRs) he mau huahana ia o ka puhi ʻana o ka lanahu i nā mea kanu mana nona nā hui pono a me nā mea hana mana.Mālama ʻia nā CCR i loko o nā impoundments o ka ʻili e like me ka slurry pulu a i ʻole i loko o nā pae ʻāina e like me nā CCR maloʻo.Hoʻokahi ʻano CCR, lele lehu, hiki ke hoʻohana ʻia no ka hoʻohana pono ʻana i ke kaʻa.I kekahi mau hihia, hiki ke unuhi ʻia ka lehu lele mai nā pae ʻāina maloʻo no ka hoʻohana pono ʻana.I ka hoʻomākaukau ʻana no ka ʻohi ʻana i ka lehu lele mai ka ʻāina pani i pani ʻia ma ka Montour Power Plant, ua kūkulu ʻia kahi kīʻaha wai hoʻopili i ka makahiki 2018 ma lalo o ke kahawai.Ua kūkulu ʻia ke kīʻaha wai hoʻopili no ka mālama ʻana i ka wai pili e hana ʻia ke ʻike ʻia ka lehu lele i ka wā e hoʻopili ai i ka wai ili i ka wā o ka ʻohi ʻana.ʻO ka palapala ʻae mua no ke kīʻaha, ua komo pū kekahi ʻōnaehana liner geosynthetic i loaʻa, mai lalo a luna: kahi papa hana ʻenekinia me ka ʻōnaehana underdrain, geosynthetic clay liner (GCL), 60-mil textured high density polyethylene (HDPE) geomembrane, non-woven cushion geotextile, a me kahi papa pōhaku pale.

Ua hoʻomākaukau ʻo Hull & Associates Inc. o Toledo, Ohio, i ka hoʻolālā kīʻaha no ka mālama ʻana i ka wai kahe i manaʻo ʻia mai kahi hanana ʻino 25-makahiki/24-hola, me ka hoʻolako pū ʻana i ka mālama ʻana i nā mea i hoʻopiha ʻia i loko o ke kīʻaha.Ma mua o ke kūkulu ʻia ʻana o ka ʻōnaehana liner composite, ua hoʻokokoke ʻo Owens Corning a me CQA Solutions iā Hull e noi i ka hoʻohana ʻana i kahi RhinoMat Reinforced Composite Geomembrane (RCG) ma ke ʻano he pale wai ma waena o ka underdrain a me GCL e kōkua i ke kaʻina hana ma muli o ka nui o ka ua. e hana ana ma ia wahi.No ka hōʻoia ʻana ʻaʻole ʻo RhinoMat a me GCL e hoʻokau i kahi pilikia ʻino a me ka paʻa o ka pali a hoʻokō i nā koi ʻae, ua hoʻomaka ʻo Hull i ka hoʻāʻo ʻana i ka ʻāʻili ʻana o ka mea ma mua o ke kūkulu ʻana.Ua hōʻike ʻia ka hoʻāʻo ʻana e paʻa nā mea me nā ʻaoʻao 4H:1V o ke kīʻaha.ʻO ka hoʻolālā kīʻaha wai pili ma kahi o 1.9 ʻeka ma kahi, me nā ʻaoʻao 4H:1V a me ka hohonu o 11 mau kapuaʻi.ʻO ka hana ʻana o ka RhinoMat geomembrane i hana ʻia i ʻehā paneli i hana ʻia, ʻekolu o ia mau ʻano like ka nui, a me ke ʻano huinahā like (160 kapuaʻi 170 kapuaʻi).Ua hana ʻia ka ʻehā o ka ʻaoʻao i loko o kahi ʻāpana he 120 kapuaʻi 155 kapuaʻi.Ua hoʻolālā ʻia nā panela no ka hoʻonohonoho pono ʻana a me ka kuhikuhi ʻana no ka maʻalahi o ka hoʻokomo ʻana ma muli o ka hoʻonohonoho ʻana i ke kīʻaha i manaʻo ʻia a e hōʻemi i ka seaming kahua a me ka hoʻāʻo ʻana.

Hoʻomaka ka hoʻokomo ʻana i ka geomembrane RhinoMat ma kahi o 8:00 am i ke kakahiaka o Iulai 21, 2018. Ua kau ʻia nā panela ʻehā a waiho ʻia i loko o nā ʻauwaha heleuma ma mua o ke awakea o ia lā, me ka hoʻohana ʻana i ka poʻe he 11.Ua hoʻomaka ka ua 0.5-iniha ma kahi o ka hola 12:00 pm o ia awakea a pale i ka hoʻoheheʻe ʻana i ke koena o ia lā.

Eia naʻe, ua pale ka RhinoMat i hoʻopaʻa ʻia i ka subgrade i hana ʻia, a pale i ka pōʻino o ka ʻōnaehana underdrain i hōʻike mua ʻia.Ma Iulai 22, 2018, ua piha ka ipu wai i ka ua.Pono e puhi ʻia ka wai mai ke kīʻaha e hōʻoia i ka maloʻo ʻana o nā ʻaoʻao o ka panel e hoʻopau ai i nā humuhumu ʻekolu.I ka pau ʻana o kēia mau humuhumu, ua hoʻāʻo maikaʻi ʻia lākou, a ua hoʻokomo ʻia nā kāmaʻa a puni nā paipu komo ʻelua.Ua manaʻo ʻia ka hoʻokomo ʻia ʻana o RhinoMat i ka ʻauinalā o Iulai 22, 2018, he mau hola wale nō ma mua o kahi hanana ua.

ʻO ka pule o Iulai 23, 2018, ua ʻoi aku ma mua o 11 mau ʻīniha o ka ua i ka ʻāina ʻo Washingtonville, Pa., e hoʻoulu ai i ke kahe nui a me ka pōʻino i nā alanui, nā alahaka a me nā hale hoʻomalu wai.ʻO ka hoʻokomo wikiwiki ʻana i ka geomembrane RhinoMat i hana ʻia ma Iulai 21 a me 22 ua hāʻawi i ka palekana no ka subgrade a me ka underdrain i loko o ke kīʻaha, inā ʻaʻole i hōʻino ʻia a hiki i kahi o ke kūkulu hou ʻana, a ʻoi aku ma mua o $100,000 i ka hana hou.Ua kū ka RhinoMat i ka ua a ua lilo ia i mea pale wai hana kiʻekiʻe i loko o ka ʻāpana liner composite o ka hoʻolālā kīʻaha.He laʻana kēia o nā pōmaikaʻi o ke kiʻekiʻe a me ka wikiwiki o ka hoʻolaha ʻana o nā geomembranes i hana ʻia a pehea e hiki ai i nā geomembranes i hana ʻia ke kōkua i ka hoʻoponopono ʻana i nā pilikia o ke kūkulu ʻana, ʻoiai e hālāwai pū ana i ka manaʻo hoʻolālā a me nā koi ʻae.
