Hot coffee by the waterfall? Yes please!

Maliau Basin is home to numerous waterfalls and has the highest number of waterfalls per unit area in the whole of Malaysia. In this footage, the frothy foam and dark colored water is a natural phenomenon due to tannins leaching out of decaying vegetation and leaves flowing out from the basin.

【20201014《學甲爐碴掩埋案專案報告》】
　　
今日（10/14）議程排定由環保局、農業局、地政局、經發局進行『學甲爐碴掩埋案專案報告』。
　
早在9/14臺南市議會就已經安排過現地會勘，也在會勘結束後進行初次的簡報與問答，Ingay在兩輪次的發言裡，主要針對法規與實況落差就教於環保局。
　
至於在9/14日提出關於 ＃環境背景值 的疑問，雖然當天環保局無法回應、嗣後書面回覆也語焉不詳（且竟取案地而非鄰地數值），但在今天的報告中已經補完，就不另行詢問。
　
而，針對數值問題，雖然環保局是按照《有害事業廢棄物認定標準》進行「毒性毒物溶出程序（Toxicity characteristic leaching procedure, TCLP）」，但實驗室的檢驗設定，是否足證爐碴掩埋後經年不會溶/釋出所含物質？這點從友人提供今早現場拍攝的照片--所謂挖出爐碴至底後再延伸向下挖掘30公分，確保無污染下方土層--的說法，不免令人擔心是否又是另一種不定時炸彈。更何況迄今還是無法確認「到底還有哪些地段號已被埋存爐碴？」「除農業/工業用地外，若埋碴地上方已構建廠房等地上物，是否得探鑽取測？」
　
另外，歷次報告皆以「粒料」描述，與案地發現的「石粉/灰粉」顯有不同，並且迄今報告無法明確描述是 ＃何種爐碴。
　
這個問題其實非常關鍵。因為在眾人關心經濟部《事業廢棄物再利用管理辦法》（參 https://tinyurl.com/yy7atnp9 ），爭議爐碴再利用的「用途」前，其實不該忽略該法第3條提到的『附表』。在這份長達76頁的附表中（參 https://tinyurl.com/y5ztcc7l ），很明確的針對不同類型的爐碴利用、儲放做不同規定。即使在電弧爐煉鋼爐碴一類，也對「氧化碴」與「還原碴」規定不同的處理與利用方式。
　
Ingay向環保局確認學甲爐碴掩埋案裡的碴種，局長坦承已經混合無法區分。但依「附表」的管制規定，這兩種爐碴是不得混合貯存（當然，精確一點的說，規定裡並沒有「不得混合掩埋」的文字），而，關於原料、製成與半成品的堆放，雖「氧化碴」與「還原碴」各有不同，但既然已混合無法區隔，邏輯上也該按較嚴格的規定處理（包含得否露天貯存、貯存場地應否為水泥混凝土鋪面、設截流溝及排水收集設施、以防塵網或阻隔牆圍封，阻隔牆高度應為堆置高度1.25倍以上）。再不濟，無論氧化碴或還原碴，再利用時都有「粒徑小於4.75公厘者，應先以其他工程材料隔離」的限制，這個規定背後的邏輯，是否同樣該適用在「掩埋」的處理方式上？
　
環保局沒能在質詢中給出答案，所以請局上同仁會後儘速回覆。另外，除了環保局官網目前有即時的爐碴清運直播、以及進度說明（參 https://web.tainan.gov.tw/epb/ ），Ingay也在會後向局長要求，今天簡報資料既然可在議會公開討論，也該放在環保局官網裡，讓市民以及關心此議題的朋友閱覽（補充：環保局已將當日簡報檔上傳至前述官網）。
　
「保護鄉土、義無反顧」，這是放在環保局官網上的宣誓，但這個責任，其實在這片土地上的所有人都該共同承擔。
　
如果你我真的像嘴巴講的這麼愛臺灣的話。
　
還是那句話：臺南好，原住民才會好。一如Ingay對26局處、37個區都盡可能跟同事們一起努力般，也有更多同事一起來關心臺南的原住民族人，真的非常感謝也超期待那個更友善之日！

Cantik kan pinggan viral yang ramai orang jual sekarang?

Tapi tak semua pinggan bercorak tu selamat! Bila pinggan-pinggan macam tu terkena haba, ada possibility untuk berlaku 'leaching' of plumbum. Plumbum ni bahaya kalau masuk dalam badan. Antaranya, sakit buah pinggang, effect pada otak - especially untuk bayi.
